Mobile computing allows users to access network services from anywhere using portable devices. It enables connectivity even without existing infrastructure and brings computing power to more mobile scenarios. Mobile objects are software programs that can carry state between different hosts, communicating with each other through cooperation of the hosts. While mobile computing provides many applications, it also faces challenges of low bandwidth, security risks, and the wide variety of devices with different capabilities. Future advances in areas like artificial intelligence and integrated circuitry may help address current limitations and further the growth of mobile computing.

3. What Is Mobile Computing?
What is computing?
Operation of computers (according to oxfords advance
learner’s dictionary)
What is the mobile?
That someone /something can move or be moved easily and
quickly from place to place
What is mobile computing?
Users with portable computers still have network
connections while they move

4. What Is Mobile Computing?
(Cont.)
 Mobile Computing is an umbrella term used to describe
technologies that enable people to access network services
anyplace, anytime, and anywhere.

5. Comparison to Wired Net.
Wired Networks
-high bandwidth
-low bandwidth variability
-can listen on wire
-high power machines
-high resource machines
-need physical access(security)
-low delay
-connected operation
Mobile Networks
-low bandwidth
-high bandwidth variability
-hidden terminal problem
-low power machines
-low resource machines
-need proximity
-higher delay
-disconnected operation

6. Why Go Mobile?
• Enable anywhere/anytime connectivity
• Bring computer communications to areas without
pre-existing infrastructure
• Enable mobility
• Enable new applications
• An exciting new research area

16. Security & Privacy
Threats:
 Wi-Fi networks are a shared network that makes it easier
for others to eavesdrop on your communication.
 Devices are Stolen and tampered.
 Cryptography.
 Connection
16

17. Security & Privacy
Solutions:
 Secure Web Browsing
 Use secure, encrypted sessions.
 Secure Internet Transactions
 Use UCI’s VPN to encrypt your network traffic.
 Always use a Personal Firewall.
 Set the firewall to deny.
 ALL incoming connections.

18. Applications of Mobile
Computing (Cont.)
 For Estate Agents
 In courts
 In companies
 Stock Information Collection/Control
 Credit Card Verification
 Taxi/Truck Dispatch
 Electronic Mail/Paging

19. Challenges
 Disconnection
 Low bandwidth
 High bandwidth variability
 Low power and resources
 Security risks
 Wide variety terminals and devices with different
capabilities
 Device attributes
 Fit more functionality into single, smaller device
19

20. Future of Mobile Computing
 Use of Artificial Intelligence
 Integrated Circuitry -> Compact Size
 Increases in Computer Processor speeds

21. Conclusion
Mobile computing has severe limitations
- however, it is far from impossible, and technology improves
all the time
Lots of challenges
- some have (good) solutions, many others are still waiting to
be solved
