摘要
拓扑结构是无线传感网络(WSN)的基础,通过对网络拓扑结构的控制,可使网络资源得到合理高效的利用.本文在经典邻近图算法的基础上,考虑到链路通信能耗最小化和均衡性的问题,提出一种新的基于本地信息的公平选择机制.通过分析多跳链路的结构特点,得出节点间相互选择的权值参数,并将节点的初始能量和剩余能量计入权值,使节点选择的数据链路传输节点是自己的逻辑邻节点.对比K-邻近图算法,实验结果显示,本文算法可使网络能量消耗更加均衡,能够延长网络生存周期.
Topology construction is the base of WSN.It can make the energy of net be used efficiently by controlling topology construction.In our article,based on the classical neighbor algorithms,,a new mechanism which based on local information,for fair select is advanced,considering the problem of link for communication consuming-balanced and minimum.By analyzing the characters of multi-hop link and taking the initial energy and remainder energy into the weigh,the weigh parameter by which nodes select each other is acquired.So a node selects the transmit nodes which are logical nodes of it selves.Result of simulation comparing with K-neighbor algorithm shows that algorithm of our article can make the energy consume more balance,and prolong the period of WSN.
