Study on the energy efficiency based on improved LEACH in wireless sensor networks

Energy efficiency and data reliability have always been the key problem in WSN. In this paper, firstly, a selection of cluster head algorithm is designed which is able to detect the energy change of nodes, rapidly ascertain new cluster head, and avoid excessive energy consumption between cluster head and cluster nodes. Secondly, differentiated service is introduced in our algorithm which makes achieve higher data reliability. Finally, evaluating our algorithm reliability and energy consumption, the simulation results show that it obtains higher data reliability, and simultaneously achieves lower energy consumption.
