Research on Low-Power Routing Protocol of Wireless Sensor Network Based on LEACH

LEACH algorithm is a key technology that restricts the life cycle of wireless sensor network (Wireless Sensor Network, WSN). Aiming at the unreasonable problem of LEACH algorithm cluster head election and clustering method, the fuzzy logic (FLS) method is adopted to adaptively select the best cluster head node considering the remaining energy of the node, the relative density of the node and the relative distance from the node to the sink node. According to the distance from the sink node to the cluster head node, a three-layer ring monitoring area is divided. Communicating with sink node in single-hop multi-hop mode. Simulation results show that the algorithm has extended the life cycle of the network.
