| Abstract: | Routing protocol of wireless sensor network(WSN)is a research hotspot in wireless sensor network.An improved LEACH protocol(LEACH-ISSA)based on adaptive t-distribution improved sparrow search algorithm(ISSA)is proposed to solve the problems of random cluster head selection,node distribution and LEACH uneven energy consumption.After preliminary clustering of LEACH-ISSA through LEACH protocol,low-energy nodes are excluded to generate candidate cluster heads.Then the fitness function is established by combining the remaining energy,the distance between nodes and the adjacent node factors.And the choice of candidate cluster heads is optimized by ISSA algorithm.Experimental results show that,compared with LEACH protocol,the cluster effect of LEACH-ISSA protocol is optimized,the energy consumption of the cluster head is reduced,the energy consumption of the nodes in the cluster is balanced,and the network life cycle is effectively extended. |
