Power Aware Cooperation Enforcement MANET Routing Protocols

Mobile Ad hoc network (MANET) is a self-organizing multi-hop wireless network, where the topology of the network changes dynamically. Security attacks and limited energy are the most critical issues in MANETs. Meanwhile, to save energy, some nodes may opt for routing misbehavior such that they take part in routes finding process but do not forward data packets. Detecting and mitigating routing misbehavior, forcing malicious nodes to cooperate, and extending lifetime of the network should be considered in routing decisions. This paper proposes a Power Aware Cooperation Enforcement (PACE) distributed mechanism to help nodes make intelligent routing and forwarding decisions.
