Research on routing protocol for wireless sensor networks
无线传感器网络路由协议的研究*

On the basis of analyzing the LEACH protocol,this paper brought up problems of the LEACH protocol algorithm and revised it, which made the algorithmic robustness strengthened. The node which energy uses up was the main reason in WSN shorten life cycle, so node priority became cluster head node which had maximal surplus energy in the process of dividing cluster, at the same time, had avoided the enormous energy expense of re-organizing, the main energy consume of these handle came to sink node whose energy were free, therefore, keeping the loads of network balance, making the lifecycle of network maximization. By simulation and analysis, improved divide cluster routing protocol is not only has good performance in energy consumption, but also makes the lifecycle of network longer.
