Mobile Ad-hoc network is a special kind of wireless networks. It is a collection of mobile nodes without having aid of established infrastructure. Mobile Ad-hoc network are vulnerable to attacks compared to wired networks due to limited physical security, volatile network topologies, power-constrained operations, intrinsic requirement of mutual trust among all nodes. During deployment, security emerges as a central requirement due to many attacks that affects the performance of the ad hoc networks. Particularly Denial of Service attack is one such severe attack against ad hoc routing protocols which is a challenging one to defend against in military communication environments.
