Abstract:
The rapid advancement of radio technologies in the 70’s stimulated the
development of mobile communication systems that would meet the needs of young
professionals on the move. Hundreds of millions of people exchange information
every day using laptops, Personal Digital Assistant (PDA), pagers, cellular phones
and other wireless communication devices. At present, wireless mobile networks
and devices are becoming increasingly popular than ever before. Users demand for
the access to information and communication anywhere and anytime. To afford
seamless connectivity it is necessary that wireless devices communicate among
themselves without routers, base stations or service providers. This has led to the
progression of adhoc networks (infrastructureless networks). Although adhoc
networks were used to setup communication for specialised, customised and
extemporaneous applications during large scale natural calamities or military
operations, the nodes in the network are not engrossed to observe the physical
happening.
