| 摘 要： | 针对LEACH协议簇头数不总是最优值和负载不均衡的问题,该文提出了高效节能分簇路由协议(EECR);采用固定簇头数目的方式,使其始终保持或接近最优值,选择簇内剩余能量最大的节点作为下一轮的簇头,并在所有簇头和sink之间建立路由树,使得簇头收集到的数据可通过路由树多跳传送到sink节点;相比于LEACH,EECR在节点节能性、负载均衡性和适用网络范围等方面都有较大提高.

| Abstract: | In order to solve the problem that the number of cluster heads in the LEACH protocol is not always the optimal one and distribution of loads in LEACH is not even,this paper proposes the energy efficient clustering routing(EECR) protocol.The EECR protocol fixes the number of cluster heads and makes it equal to or approach to the optimal number.It selects the sensor nodes which have the largest residual energy in the clusters to be cluster heads in the next round and builds a routing tree between the sink nod... |
