摘　　要：提出了一种分布式高效节能的无线传感器网络数据收集和路由协议HEEDC.此协议中传感器节点根据自身状态(综合考虑剩余能量、节点密度等因素计算得出的代价因子)自主的竞争簇首,同时为减少簇首节点的能量开销,簇首之间通过多跳方式将各个簇内收集到的数据发送给特定簇首节点,并由此簇首节点将整个网络收集的数据发送给汇聚节点.仿真实验表明,HEEDC协议比起现有的几种重要路由协议(如LEACH、PEGASIS等),能提供更加有效的能量使用效率,延长无线传感器网络的生存周期.因此,使用HEEDC协议的无线传感器网络具有更好的使用性,其监测结果具有更高的可靠性.This paper presents a high energy-efficient cluster-based data collecting and routing protocol（HEEDC） for wireless sensor networks,in which a node,according to its status（a weighted parameter）,independently makes its decision to compete for acting as a cluster head.Furthermore,HEEDC uses the multi-hop manner for inter-cluster data transmission in order to save total energy consumption.A specialized cluster head node is responsible for collecting the data from other cluster head nodes,and then transmits the aggregated data to the base station.Experimental results show that compared with the current important clustering protocols,the HEEDC protocol provides higher performance and longer network lifetime.Therefore,the reliability and availability in HEEDC is higher than that in other protocols.
