ABSTRACT
In wireless cooperative transmissions, nodes may deviate from the cooperative protocol to reduce energy consumption while still reaping the benefits of other nodes' cooperation. Misbehavior is implemented by refraining from responding to cooperation request, mimicking adverse channel conditions. From time to time (with a given percentage) cooperations requests are accepted in order to avoid being detected as selfish. In this paper, we propose a technique for detecting misbehavior of nodes in an ad hoc network using carrier sense multiple access (CSMA) and automatic repeat request (ARQ) protocol. Each node can detect control packets of ARQ among source, destination and cooperating nodes, and collect statistics on their decoding probability. Selfish behavior is detected based on uniformly most powerful (UMP) test which yields the minimum miss detection probability for a given false alarm probability.
