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 is still security issue which made it vulnerable to various attacks such as black hole which tremendously affects
the network performance. There have been several works done to mitigate this problem but
most of the proposed methods introduce overhead to the existing protocol i.e. extra control messages. Most of MANET devices are resource constraint and therefore a light solution is needed. For this reason, in this paper we proposed a method called ERDA (Enhance Route Discovery for AODV). The proposed method is able to mitigate the aforesaid problem by introducing new conditions in the routing table update process and also by adding simple malicious node detection and isolation process to the AODV route discovery mechanism. The proposed method does not introduce any additional control message and moreover, it does not change the existing protocol scheme. In
order to test the proposed method, a simulation model was developed. The simulation results show significant improvement to the network performance after ERDA is implemented in the AODV as compared to the existing AODV protocol.
