ABSTRACTy The next-generation mobile network will support terminal mobility,

personal mobility, and service provider portability, making Location

Tracking seamless.

y A location-independent personal telecommunication number (PTN) scheme

is conducive to implementing such a global mobile system.

y In this paper, I propose multi tree database architecture consists of a number

of database subsystems, each of which is a three-level.

y It also proposes indexing schemes for each type of location databases and

analyzes their efficiency and cost in terms of database access time andstorage requirement.

y Results have revealed that the proposed database architecture for location

management can effectively support the anticipated high user density in the

future mobile networks.

INTRODUCTIONy THE next-generation mobile network will be an integrated global system

that provides heterogeneous services across network providers, network

backbones, and geographical regions.

y Location Tracking is a basic service of the future mobile networks, where

terminal mobility, personal mobility, and service provider portability must

be supported.

y In a wireless network, a node (mobile-phone) will be present in a region and

each region will have a MSS.

y

Mss is mobile-switching-station or tower. Each mss will have up to dateinformation of all the nodes under its control. Nodes will be continuously

roaming i.e. it will change its location randomly.

y When ever a node leaves a region and enters another region, two region's

mss will be updated. Each mss contains two databases namely HLR and

VLR.

CONT..y The next-generation mobile network will support terminal mobility,

personal mobility, and service provider portability, making global roamingseamless.

y A location-independent personal telecommunication number (PTN) scheme

is conducive to implementing such a global mobile system.

y However, the nongeographic PTNs coupled with the anticipated large

number of mobile users in future mobile networks may introduce very large

centralized databases.

y This necessitates research into the design and performance of high-throughput database technologies used in mobile systems to ensure that

future systems will be able to carry efficiently the anticipated loads.

y This paper proposes a scalable, robust, efficient location database

architecture based on the location- independent PTNs.

y The proposed multitree database architecture consists of a number of

database subsystems, each of which is a three-level tree structure and is

connected to the others only through its root.

y By exploiting the localized nature of calling and mobility patterns, the

proposed architecture effectively reduces the database loads as well as the

signaling traffic incurred by the location registration and call delivery

procedures.

y In addition, two memory-resident database indices, memory-resident direct

file and T-tree, are proposed for the location databases to further improve

their throughput.

y Analysis model and numerical results are presented to evaluate the

efficiency of the proposed database architecture.

y Results have revealed that the proposed database architecture for location

management can effectively support the anticipated high user density in the

future mobile networks.

CONT..y Mobility management is a major challenge in mobile ad hoc networks

(MANETs) due in part to the dynamically changing network topologies.

y For mobile sensor networks that are deployed for surveillance applications,

it is important to use a mobility management scheme that can empower

nodes to make better decisions regarding their positions such that strategic

tasks such as target tracking can benefit from node movement.

y In this paper, I describe a distributed mobility management scheme for

mobile sensor networks.

yThe proposed scheme considers node movement decisions as part of adistributed optimization problem which integrates mobility-enhanced

improvement in the quality of target tracking data with the associated

negative consequences of increased energy consumption due to locomotion,

potential loss of network connectivity, and loss of sensing coverage.

CHARACTERISTICS

y MANET generally has the following characteristics:

y New members can join and leave the network any time.

y No base station is available to provide connectivity to backbone

hosts or to other mobile hosts.

y It is difficult to implement this scheme for handover and

location management.

y Each node acts as a router, forwarding packets from others

nodes.

y Communication connectivity is usually weak in the sense that

it is easily broken due to node movement.

y The previous mobile network was use different server and

each has decentralized databases.

y A local server is stored only its area users information, but

not stored the other area users information.

y For example Chennai mobile user call to the Srilanka user

means, First it search in the local mobile user and after

finished search in India and then find it in the Srilanka

server.

y It takes more time to find the user location because ofdecentralized databases.

y The communication traffic also occur when search client

side.

EXISTING SYSTEM


11/15

LIMITATION OF EXISTING SYSTEM

y Its based on location dependent PTN.

y Does not have a mobile freedom for global wise.

y Database will vary for each and every country and will not access by other

country.

y We cant able to get the clear database details of other country.

y The PTN will not able to access from one country to other country.

y PTN will vary from country to country.

PROPOSED SYSTEM

y In proposed system, the mobile network search only in server but not inclient mobile. Because all users information maintained in centralized

database server.

y The proposed multi tree database architecture consists of a number of

database subsystems, each of which is a three-level tree structure and isconnected to the others only through its root.

y By exploiting the localized nature of calling and mobility patterns, the

proposed architecture effectively reduces the database loads as well as the

signaling traffic incurred by the location registration and call deliveryprocedures.

y In addition, two memory-resident database indices, memory-residentdirect file and T-tree are proposed for the location databases to further

improve their throughput
