Mobile ad hoc network is a type of wireless network that operates without any infrastructure and base station. In MANET (Mobile Ad hoc NETwork), communications formed are temporary. Nodes in an Ad hoc network are highly mobile thus the topology of the network formed is also dynamic, nodes may join or leave the network at any time. Mobile Ad hoc networks are mainly used at places where it is difficult to establish infrastructure like in military and rescue from disasters where an infrastructure cannot be organize. Due to above mention characteristics of MANET it is highly vulnerable to security attacks.
