Mobile Computing

brisk computing is associated with mobility of hardw be, data and software in figurer
applications. Mobile computing has become possible with convergence of vigorous
communications and computer technologies, which include unsettled phones, personal digital
assistants (PDA), handheld and man- take-away computers, radio set local area earningss (WLAN),
tuner wide area networks and wireless ATMs. The increasing miniaturisation of virtually all
system components is making prompt computing a reality (Alonso and Korth, 1993; Forman
and Zahorjan, 1994). Mobile computing - the part of a portable computer capable of wireless
networking - is already revolutionising the track we use computers.
Wireless networking has greatly enhanced the use of portable computers. It allows users
versatile communication with some other people and outright telling about important events and
convenient access to up-to-date information, yet with much more flexibility than with cellular
phones or pagers. It also enables day-and-night access to the services and resources of stationary
computer networks. Wireless networking promises to do for portable computers what traditional
networks have done for desktop personal computers.



Networks enable complete personal
computers to participate in distributed systems that allow users anywhere on the network to
access shared resources. With access to a wireless network, mobile users can download news or
electronic documents, query a remote database, send or receive electronic mail, or even be
involved in a real-time video-conference with other users.
The technical challenges that mobile computing must resolve are hardly trivial. However, some
of the challenges in developing software and hardware for mobile computing systems are quite
different from those involved in the introduction of todays stationary networked systems (Forman
and Zahorjan, 1994). These challenges are discussed below in more detail. Also the implications
