A secure method on a routing protocol for ad hoc networks

Ad hoc network is collections of wireless mobile devices with limited broadcast range and resources, and no fixed infrastructure. Routing issue is one of the most basic networking issues in ad hoc network. An adversary can easily palsy the network by attacking the routing protocol. There are some secure routing protocols have been proposed for ad hoc network. In this paper is argued about the flaws in an ad hoc routing protocol that called Ariadne. This paper shows that the security proof for the route discovery algorithm Ariadne is flawed, and moreover, this algorithm is vulnerable to some attacks. For solving the shortages in this protocol is proposed the method in the route discovery algorithm. Proposed method in this paper adds the ability of the malicious node detections to this protocol.
