一种改进的传感器网络分簇分层路由协议

An improved clustering hierarchical routing protocol for wireless sensor networks

在分析了无线传感器网络中传统的LEACH和LEACH-C路由协议基础上,结合MTE路由协议思想,提出了一种新的改进型分簇分层路由协议(improved clustering hierarchical routing protocol,ICH).文中簇首节点可以采用多跳方式传输数据包,且在选择中继节点时考虑节点剩余能量,对进入下一轮的条件进行了限制.实验表明,改进后的ICH协议的节点存活率比LEACH-C好.

After analyzing the LEACH,LEACH-C hierarchical protocols and MTE protocol,we proposed a new routing protocol called ICH(improved clustering hierarchical routing protocol) for wireless sensor networks.The cluster-heads use the multi-hop communication mode to transfer data packets.And the energy of the node was considered in the selection of relaying nodes.We put forward the restrictive conditions when the network will go into the next round.Experiment result shows that the ICH acts better than LEACH-C at the...
