Mobile Ad-hoc NETworks (MANETs) are Infrastructure less networks where self-configuring mobile nodes are connected by wireless links. In MANET, each node in a network performs as both a transmitter and a receiver. They rely on each other to store and forward packets. Due to inherent characteristics like decentralization, self-configuring and self -organizing networks, they can be deployed easily without need of expensive infrastructure and have wide range of military to civilian and commercial applications. But wireless medium, dynamically changing topology, limited battery and lack of centralized control in MANETs, make them vulnerable to various types of attacks.
