Improved route error tolerant mechanism for AODV routing protocol in MANET

Abstract

The ultimate goal of this paper is to improve the route error tolerant mechanism of Adhoc On demand Distance Vector Routing Protocol (AODV) for the dynamic MANET system. In traditional AODV, if the route error occurs at the middle of transmission means the source node reconstruct the route to start the transmission from the beginning. So, the vast delay is occurred in the network and also AODV does not consider the presence of malicious node while constructing the route. In the proposed mechanism, the route error is not sent to the source node. It is send to the node which is prior to itself in the route. So, forwarder node also can handle the route failure and the proposed scheme considers the presence of malicious node while constructing the route. The performance is evaluated by using the NS2 Simulator.
