Research and Improvement of Adaptive Topology Algorithm LEACH for Wireless Sensor Network

Because of the limited battery power of wireless sensor network node, energy conservation is a key issue. This paper improves LEACH algorithm. Through taking into account the energy state and one-hop neighbor nodes of nodes, the improvement algorithm optimizes cluster head selection, and effectively reduces the possibility that the low energy or poor location nodes are elected the cluster heads, further ensures energy load balance of network nodes. The simulation results show that the improved algorithm can effectively balance the energy consumption of distribution nodes, and extend survival time of the network.
