A novel approach for non-cooperative node detection and avoidance using reputation-based scheme in mobile ad hoc network

Abstract

A mobile ad hoc network (MANET) is a collection of wireless mobile nodes that form a dynamic network without the need for any infrastructure. Due to the dynamic nature of MANET, it is prone to different kinds of malicious attacks. In order to pursue secure communication in such networks, there are many research solutions proposed for detecting and avoiding such malicious activities. As we know, MANET works properly if participating nodes cooperate in routing and forwarding. However, a node may decide not to cooperate just to save its resources but still use network to relay its traffic. In this scenario, we propose a reputationbased strategy to detect non-cooperative or selfish nodes and to select proper forwarder node for improving overall packet delivery of the network. Moreover, our proposed solution ensures data integrity. We have also done survey and performance analysis on some existing malicious attacks detection and prevention techniques available. The entire simulation has been done using the Network Simulator (NS-2) (http://www.isi.edu/nsnam/ns/) and simulation results show better delivery compared to some of other existing techniques discussed in the papers by Khamayseh et al. (J Netw 7(1):116–125, 2012), Marti et al. (Proceedings of International Conference on Mobile Computing and Networking (MOBICOM’OO), 255–265, 2000), Woungang et al. (Proceedings of IEEE Conference, 2012) and Hu et al. (IEEE J Sel Areas Commun 24(2):307–380, 2006).
