Abstract

Mobile Ad hoc Networks (MANETs) are emerging wireless networks with many distinct characteristics. MANET has the potential to be useful in many different commercial applications. However, before using MANET in commercial application, it is necessary to address different security issues related to MANET. Data routing is one of the fundamental operations in the MANET. This research work addresses security issues related to MANET routing protocols. In this paper, we consider the performance of MANETs routing protocols subject to black hole attacks. Trust management techniques aim to protect a network from the malicious behaviour of the participating nodes. This research work proposed a novel trust-based routing protocol for MANET called ITAODV, which is derived from regular AODV protocol. The proposed protocol uses an indirect trust mechanism, which takes into account the reliability of the nodes while forwarding the packets. The performance evaluation of AODV and ITAODV was carried out using Network Simulator 3 (NS-3). The experimental results demonstrate effectiveness of the ITAODV protocol against black hole attacks.
