In order to solve the problems of traditional LEACH(Low Energy Adaptive Clustering Hierar-chy)protocol network nodes,such as high energy consumption,small survival number and short survival time,an improved LEACH-AD scheme is proposed.The algorithm introduces the optimal cluster head ratio P value,adding distance factor,residual energy factor and density factor and other factors to update the threshold formula for clustering and transmission between clusters.The experiment results show that the im-proved leach-ad protocol has 138,195 and 628 rounds longer than the original LEACH protocol in the first dead node,10%dead node and all dead nodes,respectively.In terms of energy consumption,it lasted 631 more rounds than the original LEACH protocol.The improved routing protocol reduces the energy con-sumption of network nodes,thus effectively prolonging the working time of wireless networks and sensor nodes,which is of great significance to the research and development of wireless monitoring systems.
