A Wireless Sensor Network Clustering Algorithm for Smart Grid Service Demand

Smart grid has great application prospects in the power industry. How to extend network life has become a research hotspot in recent years. This paper improves the wireless sensor network LEACH algorithm by analyzing the business requirements of the Smart grid. First, the remaining energy and node density are taken into account in the cluster head election, to ensure the rationality of the cluster head selection. Then, a non-uniform clustering mechanism is adopted to construct the cluster radius of different sizes when clustering. The multi-hop mode is used to transmit data to the base station, and the distance between the cluster head nodes and the remaining energy are used as the selection basis of the next-hop relay node to achieve the purpose of equalizing the energy load. Simulation results show that compared with LEACH and LEACH-DC algorithms, the proposed algorithm can effectively balance node energy consumption and extend network life cycle.
