Outline
1 . A person (user) who moves
Between different geographical locations Between different networks Between different communication
devices Between different applications
2 . A device that moves Between different geographical locations Between different networks
What is mobility
What is the mobile? • That someone /something can move or
be moved easily and quickly from place to place
What is mobile computing? 1. Mobile Computing is when a (work)
process is moved from a normal fixed position to a more dynamic position
2. Users with portable computers still have network connections while they move
Mobile computing
Comparison to Wired
Net.Wired Networks• can listen on wire
• high power machines
• high resource machines
• low delay• connected operation • low bandwidth
variability
Mobile Networks• hidden terminal
problem• low power machines• low resource
machines• higher delay• disconnected
operation • high bandwidth
variability
Enable anywhere/anytime connectivity Bring computer communications areas without pre-existing infrastructure Enable mobility Enable new applications An exciting new research area
Why Go Mobile?
Emergency
services
Applications
Stock Information Collection/Control
Credit Card Verification
Taxi/Truck Dispatch
For legal purpose
Electronic Mail/Paging
VEHICLES Transmission of news, road
condition
Cell Phones - Unsafe Driving
Demerits
Security- Rogue Wireless Networks- Personal Theft- WEP easy to crack- Bluetooth Hacks
GPS Navigation- Vehicle Tracking for Companies
Disconnection Low power and resources Security risks Fit more functionality into single,
smaller device High error rate Power Limitation
Challenges
M --need for MobilityO --need to improve OperationsB --need to break business BarriersI --need to improve Information qualityL --need to decrease transection LagE --need to improve efficiency
Achieving benefits
Use of Artificial Intelligence
Integrated Circuitry -> Compact Size
Increases in Computer Processor speeds
Future
Wireless Communications
– Quality of connectivity– Bandwidth limitations
Mobility– Location transparency– Location dependency
Portability– Power limitations– Display, processing, storage limitations
Research Issues
Mobile Computing and Communications is useful for wireless Networks. The study of different versions will give differences between Mobile Computing and Communications, Access Control, Security etc.,
CONCLUSION
