Fig. 8

Network topology construction results based on PSO. This figure shows an example of a network construction with the lowest power consumption obtained by the PSO algorithm. Here, the red node is the coordinator, the yellow node is the router, and the green node is the end-device. It can be observed that the number of routers is 8, and the number of end-devices is 91
