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                                                                   

- Lack Of Etiquette

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.,
