Clustering Model Based on Improved LEACH Algorithm in Sensor Network

For the deficiencies of LEACH algorithm includes the lack of consideration to the consumption of energy and the problem of sensor’s topological structure, an improved clustering algorithm with energy efficient is proposed in LEACH sensor networks. Based on the classic clustering algorithm LEACH, it increases the chances for those nodes close to the clustering geographical center and the ones in the area with dense distribution to become cluster heads through introducing average energy consumption regulation parameter and density regulation parameter. When this algorithm is adopted, the selection of cluster heads is more reasonable which further optimizes the structure of cluster and balances the energy consumption of networks. Comparing with the LEACH algorithm, sensor networks’ lifetime can be relatively prolonged
