Tracking Based Secure AODV Routing Protocol

Adhoc networks are dynamic infrastructure-less network system in which nodes can communicate with each other freely. It is very different from normal network and thus prone to different kinds of attack. This makes security concerns very important. This paper proposes security improvements over the existing AODV protocol for attack detection and building up proposed Tracking based credence computation (TCV) to improve network security. When a malicious node is judged as an attacker by the credence mechanism, the improved security routing protocol will implement re-routing to isolate the attacker from the network. This algorithm includes the prompt alarm about the behavior of a malicious node to help in taking quick action against them.
