This document discusses mobile computing and related concepts: - Mobile computing allows access to network services anywhere via user and device portability between locations and networks. It includes technologies like laptops, phones, and PDAs. - Ubiquitous computing integrates computation into the environment rather than distinct computer objects, enabling more natural interaction. - Examples of mobile computing applications include web access, location-aware services, entertainment, vehicle telematics, medical, sales, and emergency response. - Challenges include limited battery life, interference issues, bandwidth constraints, dynamic network changes, and ensuring security and interoperability across standards.

19.  It is an umbrella term used to
describe technologies that
enable people to access
network services anywhere,
anyplace and at anytime.

20.  User mobility
 Between different geographical locations
 Between different networks
 Between different communication devices
 Between different applications

21.  Device portability
 Between different geographical locations
 Between different networks

22.  Mobile Computing is a generic term describing the
application of small, portable, and wireless computing
and communication devices.This includes devices like
laptops with wireless LAN technology, mobile phones,
wearable computers and Personal Digital Assistants
(PDAs) with Bluetooth or IRDA interfaces, and USB flash
drives.

23.  Ubiquitous computing (ubicomp, or sometimes
ubiqcomp) integrates computation into the
environment, rather than having computers which are
distinct objects. Another term for ubiquitous computing
is pervasive computing. Promoters of this idea hope
that embedding computation into the environment
would enable people to move around and interact with
computers more naturally than they currently do.

24.  Web Access

25.  Location Aware Services
 Find services in the local environment intelligent travel
guide with up-to-date location dependent information.

26.  Entertainment
 Ad-hoc networks for multi user games,movies,music

27.  Vehicles
 transmission of news, road condition, weather, music via DAB
 personal communication using GSM
 position via GPS
 local ad-hoc network with vehicles close-by to prevent accidents,
guidance system, redundancy
 vehicle data (e.g., from busses, high-speed trains) can be transmitted
in advance for maintenance

28.  Medical
 Nurses/Doctors in Medical offices are now usingWirelessTablet
PCs/WLAN to collect and share patient information.

29.  Sales
 Sales representatives are usingTablet PCs with Smart phones for
presentation, transmitting/access information among office, hotel,
and customer location.

30.  Emergencies
 Early transmission of patient data to the hospital, current status, first
diagnosis
 Provide mobile infrastructure in dealing with Natural Disaster
(earthquake, hurricane, fire), terrorist attacks, war, ...

31.  Travelling Salesman
 Direct access to central customer files consistent
databases for all agents mobile office

32.  Resource constraints: Battery
 Interference: the quality of service (QoS)
 Bandwidth: connection latency
 Dynamic changes in communication environment: variations in signal
power within a region, thus link delays and connection losses
 Network Issues: discovery of the connection-service to destination and
connection stability
 Interoperability issues: the varying protocol standards
 Security constraints: Protocols conserving privacy of communication
