Flow chart of reconstruction method with fixed threshold. This figure shows the flow chart of a network reconstruction method based on a fixed power threshold. As shown in the figure, configure the network and then operate it first. Next, network reconstruction is performed when the remaining rate of battery energy of any router falls below the threshold that is set to 10%. In this case, it is required that the node whose remaining rate of battery energy is lower than the threshold cannot be a router. If reconstruction is not possible, leave the network structure remains unchanged and run until the remaining energy of any node is below zero
