中文摘要: 分簇技术在无线传感器网络中得到广泛的应用. 提出了一种基于能量反馈的分簇路由算法(EFCA). 该算法以簇为单位构造数据聚合树, 解决了单跳传输外沿节点能耗过快和多跳传输时延过大的问题; 同时在簇内选择簇头对, 令主次节点分别负责簇间信息传递和簇内信息收集, 进一步减小了数据传输延迟; 提出的能量反馈机制很好的解决了网络“热区”问题. 经仿真验证, 可以有效的延长网络的生存时间.
Abstract:Clustering technology has been widely used in wireless sensor networks. This paper introduces a clustering routing algorithm based on energy feedback (EFCA). The algorithm constructs a data aggregation tree in cluster units to reduce energy consumption of the outer edge node in multi-hop transmission and reduce the delay in single-hop transmission; selects a cluster head-couple in the cluster, the primary and secondary nodes are responsible for transmission of information between the clusters and the information gatheringin the cluster, further reducing the data transmission delay; the energy feedback mechanism proposed eliminate the network “hot zone”. Simulation can effectively extend the network lifetime.
