One of the main problems with the existing ad hoc network especially in the military area is the security issue. Since the network works normally in heterogeneous mode, they may have nodes belonging to some enemy forces also which may intrude the network, get the confidential information or get hold of some other nodes and change the configurations which may lead to byzantine attacks. Hence security plays a very vital role in military applications. Also since there is no infrastructure specially meant for maintenance of such nodes, the nodes are supposed to be intelligent enough to do all the tasks related to network topology maintenance and security themselves.
