无线传感网络的能耗问题是目前亟待解决的。基于LEACH协议的研究是最普遍的。但是这些研究大都主要几种在节点的剩余能量,簇头的个数研究,但是簇头分布的均匀性和各个簇间的普通节点过量的冗余,却很少顾及。本文首先通过平均能量分组的方法产生分组,再在每个组内选择合适的簇头,然后让簇内的部分不同节点选择行的进行休眠。这样来减少普通节点的的能耗、减少簇头的数据融合能耗,进而减少整个网络的能耗。实验证明,这种方法能够很好的延长网络的生存时间。
The problem of energy consumption in wireless sensor network is urgent to be solved. Research based on the LEACH protocol is the most common. However, most of these researches mainly study the remaining energy at nodes and the number of cluster heads. However, the uniformity of cluster head distribution and the excessive redundancy of ordinary nodes in each cluster are seldom considered. In this paper, the average energy grouping method is adopted firstly to generate the grouping, then the appropriate cluster heads are selected in each group, and then some different nodes in the cluster are selected to sleep. In this way, the energy consumption of the ordinary nodes is reduced, the data fusion energy consumption of the cluster head is reduced, and the energy consumption of the entire network is reduced. Experiments show that this method can well extend the network’s survival time.
