摘要：

A cooperative theory based convergence mechanism for heterogeneous wireless networks is presented, and a theoretical optimization model for the cooperative relay selection is proposed, in which the utility function is involved. The proposed model can determine the optimal relay nodes from the global viewpoint under the conditions of equivalent transmission rates between the first and second hops. In order to decrease the computation complexity, a sub-optimal relay selection algorithm is presented. Simulation shows that the proposed cooperative relay selection algorithm can improve the overall performances dramatically.
