Wireless ad hoc networks are a collection of wireless nodes that communicate with each other without using any fixed infrastructure. Each of the nodes in the network participates as a router for forwarding packets from one node to another. Routing protocols designed for varying infrastructure are capable of withstanding ad hoc nature such as mobility and less bandwidth. Early routing protocols for MANETs failed to take security issues into account. Subsequent proposals used strong cryptographic methods to secure the routing information.
