A Mobile Ad-hoc NETwork (MANET) is decentralized type, infrastructure less wireless network of mobile nodes. Since the nodes are mobile, the network topology may change rapidly and unpredictably over time. The network is decentralized; where all network activity including discovering the topology and delivering messages must be executed by the nodes themselves. i.e., routing functionality will be incorporated into mobile nodes. Due to multi-hop routing and absence of centralized administration in open environment, MANETs are vulnerable to attacks by malicious nodes.
