A mobile ad hoc Network (MANET) is a mobile mesh network in which the wireless nodes are both hosts and routers, so they can communicate without base stations. It relies on the cooperation of all the participating nodes. The cooperation requires detecting routes and forwarding packets. The proper functioning of mobile ad hoc networks depends on the hypothesis that each individual node is ready to forward packets to all other nodes. Due to the movement of nodes from various places, the nodes can become malicious by the intruders or by any other failures. Even though many secured routing protocols can be proposed for security issues, they can only detect the failures in the route discovery. Our mechanism provides the secured route discovery against the malicious nodes even the data transfer begins in the route path. If the malicious node has been found, it drops the packets from the node and informs the source and destination node to change the path of the data transfer from the node listing.Keywords

In mobile adhoc networks, an attacker can easily disrupt the functioning of the network by attacking the underlying routing protocol. Several secured routing protocols have been proposed so far, for adhoc networks. But all of them have certain disadvantages. Hence, security in ad hoc networks is still a debatable area. In this paper, we propose to develop a Secure Authenticated Routing Protocol (SARP) for mobile adhoc networks, that uses a lightweight, attack resistant authentication mechanism. Our protocol provides an efficient security against route discovery attacks in MANET routing protocols. It quickly detects the malicious nodes, thus assisting the nodes to drop the invalid packets, earlier. It prevents malicious or compromised nodes from attacking the routes with uncompromised nodes. It also prevents a variety of denial-ofservice (DoS) attacks. Detailed simulation studies have confirmed the efficiency and effectiveness of SARP.
