Abstract: In view of the large number of sensors and the lack of networking capability on some power transmission and substation scenarios, a solution for using the relay nodes with high computing power to collect sensor information and networking is proposed. According to this solution, a clustering routing protocol algorithm (LEACH-WGR-SSA) that rotates the root node of the relay nodes -wireless gateway is proposed. The sparrow search algorithm is used to optimize cluster head election, which considers the remaining energy of nodes, the number of adjacent and location information for the election of the wireless gateway and cluster heads and joins the Levy flight strategy to avoid the algorithm falling into the local optimum. Simulation results shows that when 50% of the nodes die, the number of network survival rounds of LEACH-WGR-SSA is increased by 121.6%, 64.1%, and 6.5% compared with LEACH, LEACH-WGR, and LEACH-WGR-PSO, which balances energy consumption, prolongs the network life and improves optimization accuracy.
