An Energy-Based Clustering Algorithm in Wireless Sensor Networks
Guangxin Yue · Radio Engineering of China · 2006
Transporting information in an energy efficient manner is critical to operating the sensor network for a long period of time.LEACH is a clustering-based protocol that utilizes randomized rotation of local cluster to evenly distribute the energy load among the sensors in the network.In this paper,we propose an improved scheme that is a randomized clustering algorithm to organize the sensors in a wireless sensor network into clusters.It forms cluster in according to residual energy of sensors and distance between sensor nodes that differs from randomized rotation of LEACH.Through analytic evaluation and simulation results,we can see that the new scheme can use energy more efficient and send more data.
