摘　　要：针对水下多节点通信网络节点生存时间短、服务质量差等问题,提出了一种基于博弈论的分布式功率分配算法。首先,在效用函数中考虑网络的整体干扰水平,优化网络的SINR水平,改善网络的服务质量。其次,进一步地将节点剩余能量引入到效用函数中,使剩余能量较低时节点减小发射功率,从而提高节点生存时间。所构建的博弈模型纳什均衡点具有存在性与唯一性。最后,通过仿真验证该算法能够延长节点寿命,优化系统SINR,提高节点能量效率。For improving the survival time of the nodes and the Qos （quality of the service） in the multi-node underwater acoustic communication networks, we proposed a distributed power allocation algorithm based on game theory. First, the o- verall interference level of the network was considered in the utility function to optimize the SINR and the Qos of the net- works. Second, the residual energy was further introduced into the utility function. So that the nodes whose residual energy were lower should reduce the transmitting power, thereby increasing the survival time of the nodes. The existence and u- niqueness of the Nash equilibrium of this formulated game was proven. Simulation results show that the algorithm can ex- tend the life of nodes, optimize the system SINR and improve the node energy efficiency.
