ABSTRACT
In a mobile ad-hoc network, nodes cannot rely on any fixed infrastructure for routing purposes. Rather, they have to cooperate to achieve this objective. However, performing network functions consumes energy and other resources. Therefore, some network nodes may decide against cooperating with others; selfish nodes. Also security issues are more paramount in such networks even more so than in wired networks. In particular these networks are extremely under threat to insider; malicious nodes; especially through packet dropping attacks. Selfish and malicious nodes are termed as misbehaving nodes. Giving the selfish nodes the incentive to cooperate, while isolating the malicious nodes have been an active research area recently. In this paper, we design a novel secure reactive routing protocol for Mobile ad hoc networks (MANETs), called TRIUMF (Trust-Based Routing Protocol with controlled degree of Selfishness for Securing MANET against Packet Dropping Attack).
