摘要
为降低簇头节点的能耗和均衡网络的整体能耗,基于低能耗自适应分簇(LEACH)协议提出一种面向数据融合的路由协议.在该协议中,簇头在簇内数据融合的过程中根据成员节点的位置信息估计感知到相同事件的邻居簇;然后数据在这些簇头间进行多跳的数据融合后传递给基站.仿真结果表明,该协议能有效延长网络的生命期.
The low-energy adaptive clustering hierarchy（LEACH）for wireless sensor networks prescribes that each cluster head sends fused data directly to base station,so cluster heads that are farther away from base station consume more energy,resulting in unbalanced energy consumption of the entire network.A data fusion oriented clustered routing protocol based on LEACH is presented to reduce the energy consumption of the cluster heads and to balance the energy consumption of the entire network.In this protocol, a cluster head estimates which neighboring clusters also sensed the same event by the locations of its member nodes during intra cluster data fusion process; data is fused among these cluster heads hop by hop before transferred to base station afterwards. Simulations show that this protocol can effectively prolong the life time of the sensor network.
