Transcript of Mobile Commerce and Pervasive Computing. Mobile commerce (m-commerce, m-business): Any e-commerce...
Mobile commerce (m-commerce, m-business): Any e-commerce done in a wireless environment, especially via the Internet
2
1G: The first generation of wireless technology, which was analog based
2G: The second generation of digital wireless technology; accommodates mainly text
2.5G: Interim wireless technology that can accommodate limited graphics
3G: The third generation of digital wireless technology; supports rich media such as video clips
4G: The expected next generation of wireless technology
3
Short Message Service (SMS): Technology that allows for sending of short text messages on some cell phones
Enhanced Messaging Service (EMS): An extension of SMS capable of simple animation, tiny pictures, and short tunes
Multimedia Messaging Service (MMS): The next generation of wireless messaging; will be able to deliver rich media

5
Specific attributes of m-commerce Mobility Broad reach
Benefits of value-added attributes Ubiquity (everywhere, very common) Convenience Instant connectivity Personalization Localization of products and services
6
Widespread availability of devices No need for a PC The handset culture Vendors’ push Improvement of bandwidth
7
M-commerce hardware Cellular (mobile) phones Attachable keyboard PDAs Interactive pagers Screenphones
A telephone equipped with a color screen, possibly a keyboard, e-mail, and Internet capabilities
E-mail handhelds
8
Required infrastructure hardware Suitably configured wireline or wireless
WAN modem, wireless LAN adapter, or wireless MAN (metro-area network) adapter
A Web server with wireless support, a WAP gateway, a communications server, and/or a mobile communications server switch (MCSS)
9
An application or database server with application logic and a business application database providing e-commerce functionality
A GPS(Global Positioning System) locator that is used to determine the location of the person carrying the mobile computing device
10
Software Microbrowsers
Wireless software designed with limited bandwidth and limited memory requirements
Mobile-client operating system Bluetooth
Chip technology that enables voice and data communications between many wireless devices through low-power, short-range, digital two-way radio frequencies
Mobile application user interface Back-end legacy application software
11
Application middleware Wireless middleware Wireless Application Protocol
A set of communications protocols designed to enable different kinds of wireless devices to talk to a server installed on a mobile network so users can access the Internet
12
Wireless Markup LanguageScripting language used for creating content in the wireless Web environment; based on XML, minus unnecessary content to increase speed
Voice XMLAn extension of XML designed to accommodate voice
13
Wireless LAN (WLAN): LAN without the cables; used to transmit and receive data over the airwaves
Wireless access point: An antenna connecting a mobile device (laptop or PDA) to a wired LAN
15
Voice systems for m-commerce Hand- and eyes-free operations Disabled people can use voice commands Voice terminals are designed for
portability Voice terminals are more rugged than
keyboards Communication is about two-and-a-half
times faster talking than typing Speaking results in fewer data entry
errors
17
Interactive voice response (IVR): A computer voice system that enables users to request and receive information and to enter and change data through regular telephone lines or through 1G cell phones
Voice portal: A Web site with an audio interface that can be accessed through a telephone call
18
Physical securitya stolen device can provide the thief with valuable data and digital credentials
Transactional issuestransactions are routed over a public network
Post-transaction issuessome method of proving that a particular transaction has occurred
19
Mobile banking A large percentage of banks offer
mobile access to financial and account information
Surveys indicate there is strong latent demand for these offerings that is waiting for the technology and transmission speeds to improve
20
Wireless electronic payment systems Wireless payment systems
transform mobile phones into secure, self-contained purchasing tools capable of instantly authorizing payments over the cellular network for goods and services
21
Micropayments: Electronic payments for small-purchase amounts (generally less than $10) Wide-ranging applications, such as
making payments to parking garages, restaurants, grocery stores, and public utilities
Success depends on the costs of the transactions
22
M-wallet (mobile wallet): A wireless wallet that enables cardholders to make purchases with a single click from their wireless device
Bill paymentsA number of companies are now providing their customers with the option of paying their bills directly from a cell phone
23
Shopping from wireless devices Wireless shoppers are supported by
services similar to those available for wireline shoppers
Cell phone users also can participate in online auctions (eBay and Amazon.com)
24
Targeted advertising Knowing the current location of
mobile users (using GPS) and their preferences or surfing habits, marketers can send user-specific advertising messages
25
Hotels Hotels now offer their guests in-
room, high-speed Internet connections
A small number of hotels are testing the use of this technology for check-in and check-out, for making purchases from hotel vending machines and stores, for tracking loyalty points
26
Wireless telemedicine The storage and forwarding of
digital images from one location to another
Videoconferencing used for real-time consultation with a patient in one location and a medical specialist in another
27
Location-based commerce (L-commerce): M-commerce transactions targeted to
individuals in specific locations, at specific times
L-commerce offers: Safety Convenience Productivity
28
L-commerce basic services revolve around five key areas:
1. Location2. Navigation3. Tracking4. Mapping5. Timing
29
Necessary location-based and network technologies: Position-determining equipment
(PDE) Mobile positioning center (MPC) Location-based technology Geographic content Location-specific content
30
Global positioning system (GPS): A wireless system that uses satellites to enable users to determine their position anywhere on the earth
GPS handsets can be: stand-alone units plugged into a mobile device or
completely embedded in one
31
Geographical information system (GIS): System that integrates GSP data onto digitized map displays
Wireless 911 (e-911): Calls from cellular phones to providers of emergency services
32
Automatic crash notification (ACN): Device that automatically sends the police the location of a vehicle that has been involved in a crash
Telematics: The integration of computers and wireless communications to improve information flow using the principles of telemetry
34
Barriers to L-commerce Accuracy The cost-benefit justification The bandwidth of GSM networks Invasion of privacy
35
Pervasive computing: Invisible, everywhere computing that is embedded in the objects around us
Also know as: ubiquitous computing embedded computing augmented computing
36
Properties of pervasive computing Invisible devices Embedded microchips Always on Ubiquitous network Life-enhancing applications Consumer-centric solutions Increasing productivity Long-term vision
37
Technical foundation of pervasive computing Everyday objects have to contain
embedded microprocessors A ubiquitous network is needed to
connect these microprocessors The microprocessors must be able
to communicate with the ubiquitous network
38
Smart homes—home automation systems support: Lighting Energy management Water control Home security and communications Home theater
39
Smart appliancesInternet-ready appliance that can be controlled by a small handheld device or desktop computer via a home intranet or the public Internet
Home Alliance (internethomealliance.com)
40
A networked appliance could provide a manufacturer and the owner with information that could be used for: Capturing or reporting on the
operation, performance, and usage of a device
Diagnostic purposes—monitoring, troubleshooting, repairing, or maintaining the device
41
Improving the performance or features of a device
Controlling and coordinating devices into a sequenced pattern of behavior
Profiling and behavior tracking of a device
Monitoring consumption Tracking and optimizing the service
support system
42
Smart cars—increased use of automobile microprocessors sophisticated engine controls to meet
emissions and fuel-economy standards advanced diagnostics; simplification of
the manufacture and design of cars reduction of the amount of wiring in cars new safety features new comfort and convenience features
