摘要:

针对当前无线路由协议的能量和簇头瓶颈问题,以延长网络生存时间和提高能量利用率为目标,提出一种能量均衡无线传感器网络分簇路由协议。首先根据能量消耗最小原则,得出最优簇头数目
,并按区域划分为簇,然后通过节点剩余能量和通信代价2个参数选取簇头,并且动态地轮换簇头,最后进行仿真实验。仿真结果表明,相对于其它改进LEACH协议,本协议有效地减少能量消耗,明显增
加了网络节点存活率。

Abstract:

In order to prolong life time of wireless sensor network, a novel routing protocol of wireless sensor network based on energy balance is proposed. Firstly, the
synergic curve number of cluster heads will be found under the principle of the minimum potential energy, and then are divided into clusters by district, and the optimized
cluster will be selected according to the node residual energy and the communication cost, and replace the cluster dynamically, finally, the simulation experiment is carried out
to test the performance. The simulation shows that compared with LEACH protocol, the proposed protocol can reduce energy and improve the network node survival rate
significantly.

Key words: wireless sensor network, clustering, energyefficient, clustering head selection
