In this paper, the authors propose a new secure route discovery protocol for MANETs that overcomes the vulnerabilities of Ariadne and EndairA, due to hidden channel attacks. It uses 'authentic neighborhood' for route discovery process which potentially protects hidden channels of routing control packets, besides ensuring authenticity and integrity of routing control messages at hop-by-hop level. This authentic neighborhood is augmented by a process of traceability which uses promiscuous mode of a node to detect, diagnose and isolate the adversarial nodes that disrupt the route discovery process.
