| 中文摘要: |
| 针对无线传感器网络能量受限和能量消耗不均衡问题,提出了一种能量高效的稳定分簇(energy-efficient steady clustering,EESC)路由协议,其核心思想是:当前簇头根据其簇成员节点的剩余能量信息决定下一轮簇头,下一轮簇头上任后,非簇头节点根据能量距离函数决定加入哪个簇头,簇间通过簇头最小能量耗费判定依据来决定采用单跳还是多跳通信方式向基站发送数据．EESC路由协议每轮产生的簇头数量稳定,综合了分布式和集中式两类分簇协议的优点．实验结果表明,EESC路由协议不仅高效地利用了网络节点有限的能量,而且均衡了节点的能量消耗,显著地延长了网络的存活时间． |

| An energy-efficient steady clustering (EESC) routing protocol is proposed in order to solve the problem of limited energy supply and unbalanced energy consumption for wireless sensor networks. In the clustering mechanism, the current cluster heads determine cluster heads for next round according to residual energy of cluster member nodes. In the next round, each non-cluster head node decides which cluster head it will belong to according to energy-distance function. The communication model of single hop or multi-hop that cluster heads select to send data to base station is decided according to the criterion of minimum energy consumption. In EESC routing protocol, the number of cluster heads generated in each round is very steady. And EESC routing protocol combines the advantage of both distributed and centralized clustering protocols. Experimental results show that the proposed routing protocol not only efficiently uses the limited energy of network nodes, but also balances the energy consumption of all nodes, and significantly prolongs the network lifetime. |
