An adhoc network consists of wireless mobile nodes forming a temporary network without any infrastructure or centralized administration. Mobile Adhoc NETworks (MANET) are self-organizing and self-configuring multi-hop wireless networks where the constituents of the network changes dynamically due to mobile nodes. The node in the network not only acts as hosts but also as routers that route data from/to source/destination node in the network. Each device in a MANET is free to move independently in any direction which results in change of its links to other devices frequently. Each must forward traffic unrelated to its own use and therefore be a router. Routing in MANET has been a challenging task ever since the wireless networks came into existence.
