摘　　要：针对无线传感器网络拓扑性能优化单一的问题,本文首先定义了表征双向通信质量的指标.其后将链路质量,节点干扰,剩余能量均衡性等参数融入收益函数,设计了一种基于链路质量的自维护拓扑控制博弈算法SMGLQ.理论证明该算法能保证各节点收敛到帕累托最优.仿真实验表明它能为网络选择通信质量较好的链路,并降低能耗.In order to overcome the problem that the topology performance optimization of wireless sensor network is single,an indicator which can represent the bi-directional communication quality of a link is defined. Then the link communication quality,node interference and balance of surplus energy are integrated into the utility function. Finally,a self-maintaining topology control game algorithm based on link quality（ SMGLQ） is proposed. The theoretical analysis proves that SMGLQ algorithm can converge to a Pareto optimal. Simulation results showthat SMGLQ chooses the links with better communication quality for the network. Moreover,it can reduce the energy consumption.
