An ad hoc network is a self configuring infrastructure less network of mobile devices connected by wireless. It uses peer-to-peer multi hop routing instead of a static network infrastructure to provide network connectivity. Neither preexisting infrastructure nor centralized administration function is required and thus self-organization and adaptation are important properties .The routers are free to move randomly and the wireless topology may change rapidly and unpredictably. In MANET, there is no distinction between a host node and a router and all nodes can be source plus forwarders of traffic.
