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.
