Detection of Routing Misbehaviour in MANET using the Trusted AODV Protocol

Abstract: A Mobile Ad-hoc Network is a Decentralised Network and is a group of mobile nodes that are dynamically and arbitrarily located in such a way that the interconnections between the nodes keep on changing continuously such a decentralised network is not secure and can face many security issues one of them is attack by malicious nodes in the network, Such an attack is serious threat in MANET. The performance of AODV and Trusted AODV without any malicious nodes in the network was analysed earlier. The malicious nodes can attack can attack the control packet and misbehave in the Network. This paper introduces a trusted path irrespective of the longest or the shortest path which is capable of detecting the malicious nodes in the Network. Further the performance of Trusted AODV and General AODV with malicious activities is analysed which results that the Trusted AODV detects the malicious nodes in the Network and its performance is better as compared to AODV giving satisfactory Results.
