【摘要】 针对无线传感器网络分簇构建中存在能量有效性与负载均衡不能合理兼顾的问题,提出了一种基于博弈的能量均衡分簇拓扑控制算法GTEBC。算法构建了一个新的博弈模型,利用簇头和簇成员节点的通信代价构造博弈模型的效用函数反映网络能量有效性和负载均衡,并运用博弈的方法构建分簇拓扑,实现对网络能量有效性和负载均衡的同时优化。仿真实验表明,与LEACH算法和DEER算法相比,GTEBC算法生成的网络拓扑,具有网络能耗低和负载均衡的特点,有效延长了网络生命期。更多还原

【Abstract】 Considering the contradiction between energy efficiency and load balance in clustering topology of wireless sensor networks,a game theory based energy balance clustering topology control algorithm GTEBC is proposed.A new game model is build by using communication cost of cluster head and cluster member to construct the utility function which reflects energy efficiency and load balance of networks.Then the clustering topology is constructed to optimize the energy efficiency and load balance of networks together by game theory.Simulation results show that compared with LEACH and DEER,the network topology of GTEBC has better performance in energy comsumption and load balance,and GTEBC can prolong the network lifetime effectively.更多还原
