摘　　要：针对无线传感器网络中节点能量有限以及消耗不均衡的问题,运用势博弈理论,设计一种考虑节点剩余能量、信息传输成功率以及节点到基站之间距离的效用函数,构建博弈模型,在此基础上,提出基于势博弈的非均匀拓扑控制算法BLTC。仿真结果表明,与DIA算法、VGEB算法相比,BLTC算法能够均衡节点的能量消耗,延长网络的生命周期。Aiming at the problem of limited energy and unbalanced consumption of nodes in Wireless Sensor Networks(WSN),a utility function considering the residual energy of nodes,the success rate of information transmission and the distance between nodes and base stations is designed to construct a game model by using potential game theory.On this basis,a non-uniform topology control algorithm BLTC based on potential game is proposed.Simulation results show that,compared with DIA algorithm and VGEB algorithm,BLTC algorithm can balance the energy consumption of nodes and prolong the network life cycle.
