Lately. the MANET research has focused on providing routing services with security and previous schemes have been proposed for detecting malicious nodes in a MANET. However, theu still include some problems which malicious nodes cannot be found when they falsely report other nodes as malicious. Accordingly, we propose a novel and efficient scheme for detecting malicious nodes using report messages and a report table which is consisted of node ID both both for suspecting and reporting when the malicious nodes behave normally during the route discovery, but the other hand they drop and modify packets, or falsely report other nodes as malicious during thedata transmission. Our proposed scheme is applicable to not only DSR but also AODV. And we provide some simulation results of our proposed scheme by comparing general AODV with our porposed scheme. Simulation results show that our porposed scheme outperforms general AODV in therms of average packet loss ration and packet delivery ratio.
