无线传感器网络中LEACH算法的改进
首发时间:2020-03-26
摘要:由于LEACH算法挑选簇头时没有考虑位置等参数,导致簇头可以是满足条件任何位置的节点,进而会出现簇内成员到簇头距离远大于到基站的距离的情况,而这种情况会加剧网络能量的消耗。通过理论分析将这种情况进一步地筛选,找到了较大影响能量消耗的节点。对于这些节点,提出了改进方法:在成簇时将它们过滤掉,使之不成为簇成员,从而达到减缓网络能量消耗的目的。对比模拟实验表明改进方法有效地延长了网络生存时间。

Improvement for LEACH algorithm in WSN
Abstract:When the cluster head is selected for the LEACH algorithm, parameters such as position are not considered. As a result, the cluster head can be a node at any position that meets the conditions, and the distance between the members in the cluster and the cluster head is far greater than the distance to the base station. This situation will increase the consumption of network energy. This situation was further screened through theoretical analysis, and the nodes that greatly affected energy consumption were found. For these nodes, an improved method is proposed: filtering them out when they are clustered so that they do not become cluster members, so as to reduce the energy consumption of the network. Comparative simulation experiments show that the improved method effectively prolongs the network survival time.
