Mobile Ad-hoc networks are those networks which has no physical links between the nodes. In MANET mobile nodes dynamically forming a network topology without the use of any existing network infrastructure or centralized administration. Routing in a MANET is challenging because of the dynamic topology and the lack of an existing fixed infrastructure. In most of their specifications it is assumed that all the nodes in the network are friendly. But in the open, collaborative MANET environment practically any node can maliciously or selfishly disrupt and deny communication of other nodes. Security in MANET is a very difficult problem to incorporate without degrading the performance of the protocol.
