In order to describe processes in ways which allow for execution strategies as described above, an abstract process description language has to be designed: In such a view, mobile processes have rather similar requirements for their description as traditional (business) processes, these are among others:

3. 
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

4. 
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

5. 
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

6. 
 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?

7. 

8. 
Emergency services
Applications

11. 
Taxi/Truck Dispatch

15. 
 Cell Phones
- Unsafe Driving
Demerits

16. 
- Lack Of Etiquette

17.  Security
- Rogue Wireless Networks

Companies

18. 
 Disconnection
 Low power and resources
 Security risks
 Fit more functionality into single, smaller
device
High error rate
Power Limitation
Challenges

19. 
M --need for Mobility
O --need to improve Operations
B --need to break business Barriers
I --need to improve Information quality
L --need to decrease transection Lag
E --need to improve efficiency
Achieving benefits

20. 
 Use of Artificial Intelligence
 Integrated Circuitry -> Compact Size
 Increases in Computer Processor speeds
Future

21. Wireless Communications
– Quality of connectivity
– Bandwidth limitations
Mobility
– Location transparency
– Location dependency
Portability
– Power limitations
– Display, processing, storage limitations
Research Issues

22. 
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.,
