Energy-efficient multi-cluster head hierarchical routing protocol in wireless sensor networks
WSN中能量有效的多簇头层次型路由协议

To ameliorate the situation that some nodes die too early due to the uneven energy consumption in wireless sensor networks,this paper proposed the energy-efficient hierarchical multiple vice-cluster-head algorithm in wireless sensor networks(EHMVA),which introduced the concept of neighbor distance in the cluster head selection mechanism,used vice-cluster-head mechanism to share the energy consumption of primary cluster-heads,added the concept of link-nodes,sent data according to the errors and extended the stable cluster communication phases to reduce the frequency of cluster reconstruction.Simulation results demonstrate that the energy consumption is more even in EHMVA so as to prolong network lifetime effectively.
