本文研究了协作传输网络中中继和多用户节点之间的资源共享问题。我们将这一问题表述为卖方市场竞争，并采用非合作博弈来共同考虑中继器和用户的利益。我们还开发了一种分布式算法来搜索纳什均衡，即博弈的解。分析了该算法的收敛性。仿真结果表明，该博弈能够有效地激发自利用户节点之间的合作多样性，协调用户节点之间的资源分配。
This letter considers the problem of resource sharing among a relay and multiple user nodes in cooperative transmission networks. We formulate this problem as a sellers’ market competition and use a noncooperative game to jointly consider the benefits of the relay and the users. We also develop a distributed algorithm to search the Nash equilibrium, the solution of the game. The convergence of the proposed algorithm is analyzed. Simulation results demonstrate that the proposed game can stimulate cooperative diversity among the selfish user nodes and coordinate resource allocation among the user nodes effectively.
