The authors consider the problem of selfish misbehavior in the optimal cross-layered rate control mechanism of wireless networks. Rate control algorithms of wireless networks are designed under the assumption that network hosts will follow the algorithm specifications. In this paper, they explain a scenario in which a selfish user achieves extra throughput by misleading the scheduling component of the network. The authors find an equivalent optimization framework that captures misbehavior pattern of the selfish user. They present a solution to prevent or alleviate such a greedy behavior by imposing a cost term on the utility function of the users.
