Research on the Application of an Improved LEACH Algorithm in Smart Home

In recent years, the cluster head of the wireless sensor network in the smart home system networking system not only comprehensively considers the remaining energy of the data node but also the location information of the data node in the wireless sensor network and the node density of the data node. Factors to be considered. The LEACH algorithm has the disadvantage of slow convergence in the smart home networking system. This paper proposes an improved LEACH algorithm. The LEACH algorithm introduces the optimization of cluster head node selection by introducing the Voronoi diagram and the division of "hot zone" clusters and "non-hot zone" clusters, and then introduces improvements such as dynamic adjustment of the cluster radius. In the smart home networking system, the wireless sensor network not only greatly reduces the node energy consumption of the data node, but also reduces the load of the cluster head, so that the survival time of the data node of the wireless sensor network in the entire smart home network is extended to a certain extent This improves the survival time of wireless sensor networks.
