Wireless Networks can be broadly classified into three categories: Infrastructure based networks, Wireless LANs and Ad Hoc Networks. Infrastructure based networks are traditional cellular systems which requires base station infrastructure. Wireless LANs are very flexible within the reception area. It requires low bandwidth when compared to wired networks. Ad Hoc networks is useful when the infrastructure is not available, impractical or expensive to build.

In Cellular Wireless, spaces are divided into cells. Each cell consists of base station which is responsible to communicate with the hosts in its cell. Hosts moves from one cell to cell to another and hand off occurs, the new base station takes care of the communication. In Multi-hop wireless, mobility causes change of route. Hence it need to traverse multiple links to reach destination. Ad hoc network is a self- organizing multi hop wireless network which relies neither on infrastructure nor on the predetermined connectivity.

Rapid deployment of independent mobile users will be the need of the next generation wireless communication systems. A mobile ad-hoc network is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. Network scenarios which include establishing survivable, efficient, dynamic communication for emergency/rescue operations, disaster relief efforts, and military networks cannot
