The document defines mobile computing as computing that is not restricted to a desktop and allows users to access information from any location through portable wireless devices. It discusses that mobile computing enables connectivity anywhere and anytime through technologies like laptops, tablets, e-readers and smartphones. Some challenges of mobile computing include low bandwidth, security issues, and varying network delays due to mobility.

3. Mobile simply describes computing device that is not restricted to a
desktop.
Taking a computer and all necessary files and software out into the
field.
Being able to use a computing device even when being mobile and
therefore changing location. Portability is one aspect of mobile
computing.
A variety of wireless devices that has the mobility to allow people
to connect to the internet, providing wireless transmission to
access data and information from where ever location they may be.
New technology grwoing up withmobile communication, internet,
database, distributed computing.

5. Computing on move
Users with portable computers still have network connections while they
move
Many other names/overlapping computing paradigms:
Pervasive Computing
Ubiquitous Computing
Wireless Computing
Embedded Computing
Motivations :
Availability of wireless network at reducing communication cost
Integration of communication and computing devices
Making use of wireless network to access information and perform data
processing, resource sharing at high capacity servers.
Extend the ability and usefulness of handheld devices.
Goal :
Access to information anywhere, anytime, anyway.

physically mobile computing, perhaps prolonged disconnection.
Ubiquitous computing
a term coined by Mark Weiser in 1991.
invisible computing or subconscious computing.
computers and their functionality available to users without
being noticed.
Pervasive computing
immersive computing.
use of wearable computers.
a current name for ubiquitous computing.

13. COMPARISON TO WIRED
NETWORK
WIRED NETWORK
• high bandwidth
• low bandwidth variability
• can listen on wire
• high power machines
• high resource machines
• need physical
access(security)
• low delay
• connected operation
MOBILE NETWORK(WIRELESS)
• low bandwidth
• high bandwidth variability
• hidden terminal problem
• low power machines
• low resource machines
• need proximity
• higher delay
• disconnected operation

14. Vehicles
transmission of news, road condition, weather, music via
DAB
personal communication using GSM
local ad-hoc network with vehicles close-by to prevent
accidents, guidance system, redundancy
position via GPS
Medical
Nurses/Doctors in Medical offices are now using Wireless
Tablet PCs/WLA to
collect and share patient information.
Emergencies
early transmission of patient data to hospital
ad-hoc network in case of earthquakes

O - Need To Improve Operations
B - Need To Break Business Barriers
I - Need To Improve Information Quality
L – Need To Decrease Transaction Lag
E – Need To Improve Efficiency

18. Mobility means changes
Hardware
Lighter, smaller, energy management, user interface
Low bandwidth, high bandwidth variability
Kbit/s to Mbit/s, bandwidth fluctuation
Security risk
Devices more vulnerable, endpoint authentication harder
Heterogeneous network
Different devices, interfaces and protocols
Location awareness
Locality adaptation
Higher loss-rates, higher delays, more jitter
Connection setup time, hand-off
