Research of Wireless Sensor Routing Algorithm Based on Uneven Clustering

Among traditional wireless sensor routing algorithm like LEACH, problems like unbalanced energy consumption in wireless sensor network, node losing efficacy because of large energy consumption, period uncertainty of periodic cluster head and unbalanced energy consumption between clusters come into being. Aiming at problem of unbalanced energy consumption between wireless sensor clusters, uneven clustering strategy is used in this research. Aiming at problem in the selection of periodic clustering head, clustering head rotation mechanism based on energy threshold is used in this research. In this research, 100 sensor nodes randomly exist in a square area whose radius is 400m. Sink node is in the centre of the square area. Sensor node collects data every 2s and sends monitoring data meanwhile. Simulation result shows that total energy consumption of clustering head of the improved algorithm is far less than that of traditional LEACH algorithm in which survival rate of node is also greatly developed.
