摘    要:无线传感器网络中的节点具有有限的能量,为了延长网络寿命,提出了一种分布式的高效节能的无线传感器网络数据收集协议DEEC-MR.协议中节点根据自身剩余能量竞争簇头,每个簇头节点根据相邻簇头节点与基站的距离、剩余能量等信息寻找父簇头节点,构造一颗以基站为根的近优最小汇集树.簇头将采集到的数据聚合后沿汇集树以多跳的方式传输至基站.仿真实验证明该协议能有效降低网络能耗,与其他两种数据收集协议(LEACH,PEGASIS)相比,DEEC-MR将网络寿命分别提高1600%和200%,同时使能耗均匀分布在每个节点上,避免部分节点过早死亡,具备很高的可靠性.

关 键 词:无线传感器网络  节能  数据收集  簇头  多级路由

Abstract:Since wireless sensor networks consist of nodes with limited energy,in order to prolong network life-times,a distributed energy-efficient data gathering protocol(DEEC-MR) is proposed,in which a node according to its residual energy,independently makes its decision to compete for becoming a cluster head.Each cluster head finds a parent node according to the distance between neighbor cluster head and base station,residual energy of neighbor cluster head and so on.Thus a near optimal minimum spanning tree rooted on base station is constructed.Data gathered by a cluster is transmitted along the spanning tree to base station in a multi-hop manner.The experimental results have shown that com-pared with another two data gathering protocols(LEACH,PEGASIS),DEEC-MR can prolong sensor network lifetime by 1600% and 200%,respectively.Moreover,DEEC-MR balances the energy consumption to avoid some node dying pre-maturely,so the reliability is higher than that of LEACH and PEGASIS.
Keywords:wireless sensor networks  energy efficient  data gathering  cluster head  multilevel routing
