A novel energy-efficient clustering protocol based on specific location
Hongyan Qian, Bing Chen, Qin Xiao-lin · 2009
Wireless sensor network consists of hundreds or thousands of tiny sensor nodes, which can monitor remote environment and it's useful in military and civilian applications. The limitation of the batteries of sensor nodes necessitates that the energy efficiency is a key issue in WSN. We proposed a novel protocol LEACH-L based on the geographical location of nodes, which improves the LEACH on its clustering method, cluster-head selecting and the relay transmitting. It takes care of both residual energy and position of sensor nodes in cluster when chooses a cluster-head. Mathematic analysis and simulation show that the LEACH-L has better performance in the network lifetime, node energy consumption and network throughput.
