A Mobile Ad-hoc NETwork (MANET) is defined as an autonomous system of mobile nodes and associated hosts connected by wireless links. Every node operates not only as an end system, but also as a node to forward the packets in appropriate direction. All the nodes are free to move and organize themselves into a network. The important use of mobile ad hoc network is in battlefield. MANETs do not require the support of wired access points or base stations for intercommunication. A mobile ad hoc network, unlike a static network, has no infrastructure. It is a collection of mobile nodes where communication is established in the absence of any fixed foundation. The only possible direct communication is between neighboring nodes.
