摘要
在多源多中继协作网络中,为避免协助同一源节点的中继节点之间过度干扰并实现中继节点的效用最大化,提出了一种在双层博弈框架下的联合功率控制和源节点选择的分布式算法。该算法通过中继节点功率控制的非合作子博弈与源节点选择的演化子博弈交替迭代,在抑制中继节点之间干扰的同时实现了中继节点对源节点的合理选择,并证明了双层博弈纳什均衡的唯一存在性。仿真结果表明,本文提出的双层博弈分布式算法可使系统收敛至纳什均衡。
In multisource multirelay cooperative networks,to avoid the interference among the relays that assist the same source and maximize the relay utility,we propose the joint power control and source selection distributed algorithm,which is based on two-level game.By using the alternate iterations between the non-cooperative game of power control and the evolutionary game of source selection,the proposed distributed algorithm can effectively suppress the interference and choose the optimal source.Furthermore,we prove that the two-level game model has the unique Nash equilibrium.Simulation results show that the proposed two-level game distributed algorithm can converge to the Nash equilibrium.
