Low-Power Clustering Routing Algorithm EFCA Based on Energy-Feedback in WSN
WSN中基于能量反馈的分簇路由算法EFCA

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.
