AODV Routing Protocol Performance in Malicious Environment

Abstract

The Mobile Ad-hoc Network (MANET) is constructed based on wireless medium and it is of self organizing manner. MANET is simple to set up and has changing topology. The mobile Ad-hoc networks are in danger of different attacks because MANET operational environment is open and dynamic. In MANET, data transfer use the different Routing protocols. Selfish (Malicious) node work is completely different as compared to normal Mobile nodes. Malicious nodes have capability to remove or modify the Routing Information. It also sends the fake Route Request to access user’s data. It is responsible for attacks on the existing normal mobile nodes and creates receiver collision, restricted transmission power, fake misbehavior etc. Malicious node carries different types of attacks on the networks so it directly or indirectly effects the routing Performance. The intention of this work is to check and analyze the Network performance in malicious environment and provide prevention for the attack. Throughput and Delay are analyzed for Denial of Service (DoS) attack and prevention scenarios.
