Traditionally, routing protocols for mobile ad-hoc networks (MANETs) assume a safe and a cooperative network setting. In practice, there may be malicious nodes attempt to disrupt the network communication by launching attacks on the routing protocol itself. Protecting the route from malicious attacks is an important yet challenging security issue in mobile ad hoc networks. In this paper, we proposed challenged node technique is to detect and react on the adversary nodes at the route discovery phase. In challenged node technique, any intermediate node new route reply verifies with next hop node challenged replay by its mitigate neighborhood nodes. In essence, new route replay verification algorithm describe about how efficiently it detects the malicious node at route discovery process. Eventually our simulation results are shown that challenged node technique has better malicious node detection probability and packet delivery ratio than existing technique.
