摘要: 运用对策论中的Stackelberg策略,提出了基于TDMA-CDMA的分簇结构无线传感器网络(WSN)的反向链路功率控制的新算法。根据TDMA机制和CDMA机制相结合的分簇结构无线传感器网络的基本特点,以网络中的簇为单位,建立了一个该簇簇头采用Stackelberg策略控制节点发射功率以达到最大化能量有效性并兼顾网络寿命的数学模型。仿真结果表明Stackelberg策略能起到控制功率及激励网络优化的作用。

Abstract: This paper develops a power control algorithm on the reverse link of clustering Wireless Sensor Network(WSN) based on TDMA-CDMA with Stackelberg strategy.According to the features of clustering WSN based on TDMA-CDMA,the paper builds a mathematic model of a cluster in which the cluster head controls power of nodes in the cluster to maximize energy efficiency and increase network lifetime.Simulation results show that Stackelberg strategy can serve as an incentive strategy to optimize system performance.
