Speech Topic: Flow-Net Accountable Logging and Applications

Abstract: Accountability implies that any entity should be held responsible for its own specific action or

behavior so that the entity is part of larger chains of accountability. One of the goals of

accountability is that once an event has transpired, the events that took place are traceable so

that the causes can be determined afterward. The poor accountability provided by today’s

computers and networks wastes a great deal of money and effort. This is due to the simple fact

that today’s computing and network infrastructure was not built with accountability in mind.

In this talk we introduce our previous work: accountable logging methodology called flow-net.

We apply this methodology to many applications ranging from operating system design to

computer networks.

Speech Topic: Multi-degree Detection of Web Spam with Web Quality

Features

Abstract: Web spam refers to some tricks, which try to mislead search engines to increase the rank of some Web

pages than they deserved. Combating Web spam is a significant and urgent task.

In this talk, the taxonomy of Internet spamming and the state-of-art of spam detection are briefly

introduced. A graded detection approach will then be discussed. In this approach, we regard Web spam

as one of Web quality abnormalities and exploit quality features from Web source, content and usage

dimensions. Web spam detection is usually viewed as binomial classification. However, the grey spam

zone between abidance by rules and purely malicious must be ascertained. We investigate the

multinomial classification in terms of Web content risk levels due to different degrees of Web

spamming. The proposed multi-degree classification mechanism can discover Web spam at different

harmful degrees and can put well-directed detection into effect.

Speech Topic: Using the Balanced Scorecard to Create Information Systems

that Help Enterprises Establish and Fully Execute Strategy

Abstract: It is increasingly important to develop information systems to motivate team members to fulfill

organizational goals and objectives in accordance with the organization’s strategy. Historically,

enterprise leaders and managers have focused on one or few facets of success, such as

businesses focusing solely on financial profits or academic and research institutions focusing

solely on teaching or research productivity. In today’s competitive global environment, for

organizations to excel, prosper, and maintain viability a more balanced approach is needed. An

adaptation of the balanced scorecard, a management and information system developed by

Harvard professor Robert Kaplan and consultant David Norton can provide a well-organized

backdrop to help formalize a shift from a narrow management focus to one that will help

develop and execute a more balanced strategy. Instead of focusing solely on one or few

perspectives, such as financial objectives, the balanced scorecard is an integrated set of

performance measures organized around four distinct perspectives – financial, customer,

internal, and innovation, learning, and growth. The use of an adaptation of the balanced

scorecard can help organization leaders create balanced strategies and help them manage their

enterprises to achieve full execution of their strategies through the use of objectives, measures,

targets, and initiatives. The presentation will begin with an introduction of an adaptation of the

balanced scorecard, followed by a basic example of its use, and will conclude with a listing of

available printed and online resources for further study and information.

Speech Topic: Bandwidth Efficient Multicast in HetNets

Abstract: With the popularity of mobile multimedia applications, multicasting over heterogeneous

networks (HetNets) has become a hot research topic in the field of wireless communications.

Multicasting enables the multimedia applications (e.g., IPTV, video conferencing) to deliver the same

information to a group of users simultaneously via the naturally-broadcasting wireless medium, thereby,

improving the spectral efficiency. On the other hand, since the traditional homogeneous networks

cannot keep pace with the explosive growth of mobile data demands driven by the multimedia

applications, it’s believed that the only scalable way is the interworking of the HetNets.

Within a HetNet, the member stations of a multicast stream are distributed in multiple networks.

Meanwhile, the member stations covered by the same network may experience different channel

conditions and support different modulation and transmission bit-rates. Therefore, the issue of how to

select networks to serve the multicast stream and determine the transmission rate (i.e.,) in each selected

network arises naturally. In this talk, I will address the issue of efficient resource allocation or

bandwidth allocation. As a piece of our recent research work, a novel design of a joint network selection

and rate selection scheme for the multicasting in heterogeneous networks is proposed with an aim to

minimize the overall bandwidth resources consumed by the multicast stream.

Tsinghua University, China

Keywords: Stochastic Resonance; PSK; Parameter Estimation; Cramer-Rao Bound.

Abstract. Stochastic Resonance (SR) is a nonlinear phenomenon that the input

signal's signal-to-noise ratio (SNR) could be enhanced under special conditions. This

paper proposes a novel parameter estimation algorithm for PSK signals based on SR. By

introducing a nonlinear system into traditional estimation algorithms to enhance the

signal's SNR, this proposed algorithm can achieve higher accuracy with respect to the

traditional algorithm at the same SNR condition. Computer simulation shows the

efficiency of this new algorithm.

A MAI Cancellation Algorithm with Near ML Performance

Yachuan Bao. Baoguo Yu

State Key Laboratory of Satellite Navigation and Positioning Engineering, China

Keywords: Spread spectrum communication, multiple access interference, ML

Performance, low arithmetic complexity..

Abstract. Spread spectrum communication has been widely used in many

communication system because of its anti-interfere and anti-interception properties. The

existing multi access interference (MAI) restraint technology which could be classified

as associated determination and interfere cancellation cannot achieve the unification of

low arithmetic complexity and high determination performance. For instance, the usual

linear associated determination method has low arithmetic complexity but poor

performance, while the maximum likelihood (ML) method has the best performance but

no feasibility. In this article, the causation and the influence to the system performance

of MAI are analyzed systematically based on the theory of spectrum communication,

and the representative methods are described and summarized. Based on normal

interfere cancellation algorithm, a new dimensional reduced associated determination

algorithm with near ML performance is presented and proved to be with low complexity

and near the highest theoretical performance by theoretical calculation, complexity

analysis and simulation validation. This algorithm significantly improves the application

value and feasibility of associated determination technology and has significant

importance in solving the possible MAI problem in the spread spectrum communication

systems in the future.

Micro Mobility Management For Dual Connectivity in LTE HetNets

Min-Soo Woo, Seong-Mun Kim, Seung-Eun Hong and Sung-Gi Min

Korea University, Republic of Korea

Keywords: LTE-A, HetNet, dual connectivity, mobility anchor

Abstract: A Dual Connectivity architecture has been proposed by 3GPP for

enhancement of small cells in long term evolution heterogeneous networks. A Master

eNodeB (MeNB) handles handovers on behalf of the Mobility Management Entity

(MME) and the Serving Gateway (SGW) for secondary eNodeBs (SeNB) located within

the coverage of MeNB. Workloads of the MME and the SGW are moved to the MeNB.

Small cells can be concentrated in crowded downtown or buildings in the heterogeneous

network environment. The number of handovers may be increased due to concentrated

small cells having small coverage, so the workload of the MeNB can be increased inside

the hot spot. We propose a micro mobility management scheme to offload the workload

of the MeNB to other components. The proposed scheme introduces a mobility anchor

(MA) which processes the handovers between SeNBs on behalf of MeNB. Simulation

results indicate the reduction of the workload of the MeNB due to the MA.

classical least squares (LS) algorithm severely degrades in NLOS environments. An

improved self-learning LS localization algorithm is also introduced, overcoming the

drawbacks of LS estimator that it requires at least three range estimates for an

Keywords: Secrecy outage probability, the probability of nonzero secrecy capacity,

single input multiple output, maximal ratio combining, underlay cognitive radio

networks, Rayleigh fading channels.

Abstract. In this paper, we investigate the secrecy outage performance of maximal

ratio combining (MRC) in cognitive radio networks (CRNs) over Rayleigh fading

channels. In a single input multiple output wiretap system, we consider a secondary user

SU-TX transmits confidential messages to another secondary user SU-RX equipped

with ( ) antennas while MRC technique is adopted to improve its received

signal-to-noise ratio. Meanwhile, an eavesdropper exists to overhear the information

between SU-TX and SU-RX. SU-TX adopts the underlay strategy to meet the quality of

service of the primary user without spectrum sensing. In this paper, we derive the

closed-form expressions for the secrecy outage probability and the probability of

nonzero secrecy capacity of MRC scheme in CRNs over Rayleigh fading channels.

Simulations are conducted to validate the accuracy of our proposed analytical models.

Technology, China

Keywords: global navigation satellite system; contact plan design; constraint

optimization; simulated annealing; communication delay; contact graph routing

Abstract. By introducing inter-satellite links (ISLs), global navigation satellite system

(GNSS) can achieve inter-satellite ranging, which can enable autonomous navigation,

and inter-satellite communication, which can enable the GNSS to form a global

network. Due to the resource constraints of satellite platforms, only limited number of

ISLs (e.g. only one ISL) can be equipped on one navigation satellite, which makes the

navigation satellite network a delay/disruption tolerant network (DTN). Generally, the

number of ISLs is less than the number of visible satellites; thus, only those visible

satellites which can together meet an overall goal shall be selected. Therefore, contact

plan, which comprises all future contacts among satellites, needs to be carefully

designed to accommodate the constraints of both inter-satellite ranging and

inter-satellite communication. In this paper, a topology handling scheme based on finite

state automaton is first presented as the orbiting of GNSS is periodic. Secondly, the

contact plan design problem is formulated as a constraint optimization problem with the

inter-satellite ranging as a constraint and inter-satellite communication delay as the

optimization object. Thirdly, a heuristic algorithm based on simulated annealing is

proposed to compute the contact plan. Simulation results show that the delay

performance of optimized contact plan is improved and the delay of contact graph

routing under optimized contact plan is also improved.

Keywords: Database, Synchronization, Android, Conflict Resolution.

Abstract. Past decade has witnessed meteoric advances in the field of mobile

computing owing to the development of affordable hardware technologies as well as

user-friendly software platforms. Android, the platform marketed by Google has

boomed in sales over the past few years making it one of the major mobile platforms in

the market. The steady growth of wireless information and communication technology

in convergence with rise in the penetration of Internet has led to the evolution of a wide

range of mobile applications like news, multi-player games, social networking,

messaging, etc. that need to access remote data. For the optimal functioning of all these

applications an efficient synchronization mechanism is vital. However smart-phones

have limited computational resources, power restrictions and intermittent Internet

connections which pose a challenge for smooth synchronization. This paper proposes a

two-way data synchronization mechanism between multiple Android clients and a

central server to address these challenges. We employ a batching logic to ensure

efficient data transfer in poor network environments and a server-side conflict resolution

mechanism to reduce overhead on the clients, which ensures optimal processing and

battery power consumption by the clients.

South Africa

Keywords: WSN, RFID, sensor networks, traffic control.

Abstract. The road transport profile in the highly developed urban areas in South

Africa (SA) is characterized by sizeable and total dependence on cars. For over the years

now, the amount of vehicles users on SA roads has increased enormously and is

becoming a major concern to transportation specialists and decision makers. At present

there is no automatic system available for vehicle traffic monitoring and congestion

avoidance in SA. The existing methods for traffic management, surveillance and control

are not adequately efficient in terms of performance, cost, maintenance, and support. In

this paper, we present the results of the implementation of our novel model for vehicles

traffic monitoring using wireless sensor network between two major cities in South

Africa namely Johannesburg and Pretoria. Our novel model uses a wireless sensor

network (WSN) as an instrument to control traffic signals along the roadsides, while the

RFID scanner is used to identify vehicles in the congestion areas so that the traffic

officer at the Traffic Monitoring Centre (TMC) can make use of Global Positioning

System (GPS) by establishing the position of the vehicle at any point on the roads and to

determine the appropriate roads for motorists.

Management Department, Tobin College of Business, St. John’s University, USA

Keywords: e-commerce, movie stream, streaming, movie download, movie rental,

DVD rental.

Abstract. Traditional movie DVD rental model has been challenged by a new

business model of movie stream. Movie stream possesses convincing advantages over

the traditional DVD rental. E-commerce shows a trend in the movie industry that

consumers can stream comparable quality movies and TV shows directly from the

Internet instead of waiting for the DVDs in the mail. Thanks to global technology

advancement, movie stream has already prevailed. This study focuses on consumers’

preferences of decision making variables for streaming movie from the Internet and the

traditional DVD movie rental. The results indicate that consumers are shifting from

DVD movie rental to movie stream, while home entertainment industry needs to

improve both in technology and customer service. The consumers favor movie

streaming and make it better competing with other ways of watching movie. The quality

of movie stream and renting DVD disks may be less important for movie viewers.

Movie industry should make movie stream easy to watch.

complex relationship among the information data, heterogeneous and cyberization are

the main trends of the big data. Therefore, how to analyze and manage the data based on

network analysis is one of the most urgent problems. In this paper, we analyzed the

trends and networking characteristics of current information data development. With the

analysis of current information data and the dimension of the relationship, we mined the

Keywords: Intrution Prevention System, Software-Defined Networking (SDN),

OpenFlow, Cloud Computing, Botnet Detection.

Abstract. Software-Defined Networking (SDN) is an emerging architecture that is

ideal for today’s high-bandwidth, dynamic network environments. In this architecture,

the control and data planes are decoupled from each other. Although much research has

been performed into how SDN can resolve some of the most-glaring security issues of

traditional networking, less research has addressed cloud security threats, and, in

particular, botnet/malware detection and in-cloud attacks. This work proposes an

intrusion prevention system for cloud networking with SDN solutions. To realize

collaborative defense, mechanisms of botnet/malware blocking, scan filtering and

honeypot are implemented. Malicious traffic is isolated because bot-infected VMs are

removed effectively and efficiently from the private cloud. The scanning behavior can

be filtered at a very early stage of prevention, making the VMs less exploitable. A

honeypot mechanism is also deployed to trap attackers. Experimental results show the

high detection rate, high prevention accuracy and low vulnerability of the proposed

system.

Keywords: Code Generation, String Matching, Intrusion Detection System

Abstract. The common means of defense for network security systems is to block the

intrusions by matching the signatures. Intrusion-signature matching is the critical

operation. However, small and medium-sized enterprise (SME) or Small Office Home

Office (SOHO) network security systems may not have sufficient resources to maintain

good matching performance with full-set rules. Code generation is a technique used to

convert data structures or instruction to other forms to obtain greater benefits within

execution environments. This study analyzes intrusion detection system (IDS)

signatures and discovers character occurrence to be significantly uneven. Based on this

property, this study designs a method to generate a string matching source code

according to the state table of AC algorithm for embedded network intrusion detection

platforms. The generated source code requires less memory and relies not only on table

lookup, but also on the ability of processor. This method can upgrade the performance

by compiling optimization and contribute to the application of network processors and

DSP-like based platforms. From evaluation, this method requires use of only 20%

memory and can achieve 86% performance in clean traffic compared to the original

Supporting Multi-function

Keywords: cloud storage, data sharing, privacy-preserving, data dynamic, active

attack, proxy signature, Lagrange interpolating polynomial.

Abstract. The most common concerns for users in cloud storage are data integrity,

confidentiality and availability, so various data integrity auditing schemes for cloud

storage have been proposed in the past few years, some of which achieve

privacy-preserving public auditing, data sharing and group dynamic, or support data

dynamic. However, as far as we know, until now yet there doesn’t exist a practical

auditing scheme which can simultaneously realize all the functions above; In addition,

in all the existing schemes, block authentication tag (BAT) is adopted by data owner to

achieve data integrity auditing, nevertheless, it’s a arduous task to compute BATs for

the resource-constrained data owner. In this paper, we propose a novel

privacy-preserving public auditing scheme for shared data in the cloud, which can also

support data dynamic operations and group dynamic. Our scheme has the following

advantages:(1) we introduce proxy signature into the existing auditing scheme to reduce

the cloud user’s computation burden; (2) by introducing a Lagrange interpolating

polynomial, our scheme realizes the identity’s privacy-preserving without increasing

computation cost and communication overhead, moreover it makes group dynamic

simple;(3) it can realize the practical and secure dynamic operations of shared data by

combining the Merkle Hash Tree and index-switch table which is built by us; (4) to

protect the data privacy and resist the active attack, the cloud storage server hides the

actual proof information by inserting its private key in producing proof information

process. Theoretical analysis demonstrates our scheme’s security.

Keywords: Circle curve fitting; Newton’s rings; Least square method; Matlab.

Abstract. Circle curve fitting is always the one of the hot issues of the engineering

technology field, circle curve fitting is good or bad depends not only on the fitting

algorithm, also depends on the quality of the fitting data. Especially a certain number of

disturbed observation points with errors are often used to fit a circle, which will impact

the accuracy of least square fitting. This paper proposes an novel method, according to

the data of Newton’s rings special features. Using the software of Matlab automatically

extract the points from the Newton’s rings image, and making circular curve fitting by

least square method. The algorithm can not only effectively extract data on the circle of

the Newton’s rings image with noise, even on incomplete Newton’s rings image, and get

the fitting result with higher accuracy.

School of Computer, National University of Defense Technology, China

Keywords: component; label propagation; modularity; complex network; community

structure; greedy.

Abstract. the discovery of high-quality community is a hot spot in social network

analysis and many algorithms have been proposed to discover communities. To find

potential community structures, a community discovery algorithm based on label

propagation will propagate the label of nodes in social networks, but this method

contains uncertainty and randomness, and is very sensitive to the structure of social

networks, which causes the final result to be highly unstable and contains a huge

number of small and fragile societies. Therefore, a novel called

Modular-Label-Propagate-Based algorithm for community discovery is proposed. This

algorithm starts with the propagation of the network vertexes, and then binds the nodes

with compact structure. Label propagation of the vertexes is executed according to the

order of the degree. The thought of greedy method is applied, which works according to

the sequence of the neighbor node size of current vertexes, if the module value

increases, the sequence will be renewed. Experiments have been conducted on data sets

with different characteristics. The experimental results show that modular label

propagation algorithm can significantly improve the quality, effect and stability of the

found communities, and be close to a linear complexity.

Abstract. A new DOA estimation algorithm based on the sparse approximate

representation of the received signals is proposed. Compared with subspace algorithms,

the new algorithm with superresolution, needn’t a priori information of the number of

signals, therefore it can deal with coherent signals. In the novel method, mixed norm

combined 0-norm and 2-norm is used to aid sparse approximate representation, then the

number of signals and signals’ DOA estimation is obtained. The numeric results show

good agreement with the proposed theorem.

Keywords: Derivative sampling; FRFT filters; image scaling; SDS formula.

Abstract. In this paper, based on the derivative sampling in the fractional Fourier

transform (FRFT) domain, we present a novel image scaling algorithm. The proposed

algorithm uses the second order derivative sampling (SDS) formula we derived in the

paper, and employs the FRFT filters for the first time. Besides, we have exploited two

evaluation criteria of different image scaling algorithms, the standard deviation for

evaluation of the blur and the average curvature for evaluation of the aliasing.

Experimental results show that our proposed algorithm has fine-edge characteristic, less

blur and aliasing than some classical image scaling algorithms. Moreover, our algorithm

is competitive for quality with the Papoulis algorithm.

Abstract. In this paper, we propose a geometric features extraction approach for

RGB-D image and its application in intrinsic scene properties recovery. Our approach

extracts geometric features, and make use of both 3D shape information from depth map

and edge information from RGB image. Geometric features are categorized as occlusion

edges and fold edges. The proposed method can not only extract the edge information

from the RGB–D image accurately and efficiently, but also classify the edge

information effectively. Moreover, our algorithm is close to the real time processing.

Besides, we present an application of these geometric features as edge-based intrinsic

scene properties recovery. Experimental results demonstrate that our proposed of

geometric features extraction and edge-based intrinsic scene properties recovery

Application of Residue Number System (RNS) to Image processing

Using Orthogonal Transformation

Keywords: RNS; Orthogonal transformation; Walsh Hadamard transform; Fast

Walsh Hadamard transform; Transformation matrix.

Abstract. Several techniques for image encryption have been proposed over the years

with significant consideration of basic cryptographic goals such as authentication,

integrity and confidentiality. Recently, another method for encrypting image data using

an Orthogonal transform namely Walsh Hadamard transform on residual number system

have been proposed. In this paper, we basically analyse this approach and propose an

efficient method for this type of encryption scheme. We modify the transform algorithm

of the previous technique by implementing the Fast Walsh Hadamard transform

algorithm. The fast Walsh Hadamard transform algorithm has been proved to be the

efficient algorithm to compute the Walsh Hadamard transform with computational

complexity of O(N log N). We emphasise that the naive implementation of the Walsh

Hadamard transform yields a computational complexity of O(N2). In this paper we

demonstrate the efficiency of our approach using 32 chosen eigenvalues in the key

generation algorithm. The eigenvalues are derived from a reference image. Throughout

the processes on the image data, we use modular arithmetic to ensure that computations

with the resulting RNS become very efficient. Moreover, the approach considers image

in a divided matrix domain and finally combines all independent cryptographic

operations as encryption is a one-to-one mapping. This deals with the possibility of

having any pixel value ill-stored or wrongly received at the receiver end, without

affecting the decryption process. However, the final recovered image will differ by a

negligible amount.

Abstract: In this paper we focus on personalized recommendation algorithm for

time validity. As our dataset is from a private source, we first analyzed deal

characteristics and found that deals under category “dining”, “wellness” and “activities”

have a high probability of having the same keywords in the deal names, which suggests

a repeated buying pattern. Then we computed the keyword associations from the dataset

and found meaningful patterns. Based on the keyword association rules, we proposed a

new recommendation algorithm which combines baseline algorithm and keyword

association, resulting in significant improvement in percentage of hits, average rank and

network (CNN), Objectness.

Abstract Automatic vehicle detection from high-resolution remote sensing images

plays a fundamental role in a wide range of applications. Various approaches have been

proposed to address this issue in decades, however a fast and robust approach has not

yet been found. It is still a very challenging task, due to the complex background,

diverse colors and occlusions caused by buildings and trees. Traditional methods suffer

from either high time complexity or low accuracy rate. To overcome the above

shortcomings and consider the aforementioned difficulties, in this paper, we propose a

simple and efficient approach to detect vehicles automatically. The proposed model lays

emphasis on both speed and accuracy of vehicle detection, thus our proposed model

consists of two stages: (1) To speed up localization, we apply the newly proposed binary

normed gradients (BING) to extract region proposals. (2) To enhance the robustness and

improve the accuracy rate, we use convolutional neural network (CNN), which

combines feature extraction and classification. Therefore we modify the BING and

design our own architecture of CNN to solve our problem. By comparing with

start-of-the-art methods in extensive experiments, we demonstrate the effectiveness of

the proposed approach in both speed and accuracy. Specifically, our method is more

than 10 times faster than traditional methods, and our average accuracy is higher than

state-of-the-art methods.

Group Switch-and-Stay Combining with Branch Partition for Space

Diversity

Keywords: group switch-and-stay combining; space diversity; switch-and-stay

combining; selection combining; optimal switch threshold

Abstract. Group switch-and-stay combining (GSSC) with branch partitions is

proposed for a low-complexity multi-antenna selection in a receiver diversity system.

The GSSC can enhance the performance of conventional switch-and-stay combining

(SSC), and also has a lower complexity than maximal-ratio combining (MRC) or

selection combining (SC). With the GSSC scheme, multiple antenna branches are

divided into non-overlapped groups. In each group, the branch with the maximum

signal-to-noise ratio (SNR) is used for threshold-based group switch. With particular

grouping and threshold choosing, both SC and SSC schemes become different special

cases of the GSSC scheme. For performance illustration, BPSK signaling on

independent and identically distributed (i.i.d.) flat Rayleigh fading channels is

considered, and the corresponding bit error probability (BEP) and outage probability are

derived and manipulated into closed-forms. To minimize the BEP, locally optimal

switch thresholds (STs) are defined and derived. For grouping with the same number of

branches and an identical switch threshold (ST), the locally optimal ST becomes

globally optimal. Numerical results are presented for the performance illustration and

29

comparison.

Abstract. Interference alignment (IA) is one of the promising technologies to solve

the co-channel interference in wireless communication systems. It can effectively

improve system capacity and reliability. Based on consideration of engineering

applications, the realization of interference alignment for three-cell MIMO cooperative

30

communication system is studied and then a precoding matrices group selection method

criterion was proposed in this paper. Firstly, all the transformation matrices in

cooperative communication system are calculated, and the precoding basis is selected

according to the Max-SINR criterion. Secondly, the precoding matrices and interference

suppression matrices are designed and optimized based on the singular value

decomposition of channel and the maximum chord distance of matrix. Simulation

results show that, the proposed optimized algorithm outperforms other known

interference alignment algorithms in terms of throughput and the energy efficiency.

Further, the optimized algorithm also has advantage in spatial-correlated channel and

has better engineering applicability than other algorithms.
