Black hole effect mitigation method in AODV routing protocol

Abstract

Ad hoc On Demand Vector (AODV) is a reactive routing protocol in Mobile Ad hoc Network (MANET). Although the protocol has been around for quite some time, but there are still security issues which make it vulnerable to attacks such as black hole attack which subsequently affecting its performance adversely. There have been several previous works done to mitigate this problem but most of the proposed methods incur overhead to the existing protocol. Most of MANET devices are resource constraint and therefore a light solution is highly and preferably needed. For this reason, in this paper we propose a method called EAODV (Enhance AODV) based on our previous work called ERDA. Similar to ERDA it does not introduce any overhead and moreover, it does not change the existing protocol scheme. The new proposed method is able to enhance ERDA by introducing one extra parameter, which checks for control message from destination node. In simulation, EAODV has shown outstanding results as compared to ERDA besides significant improvement to the network performance as compared to the normal AODV protocol.
