Executive Summary

Cooperation in wireless networks is beneficial for both throughput and power consumption, but requires that nodes are willing to cooperate. As the Nash equilibrium for each node would be a non-cooperative strategy, monitoring nodes' behavior is essential to ensure cooperation. In this paper, the authors present a monitoring approach for networks implementing Automatic Repeat reQuest (ARQ) and Carrier Sense Multiple Access (CSMA). Node misbehavior is detected by listening to all control packets in the network and comparing the packet decoding probability when the monitored node is a destination and when it is a potential cooperator.
