Cluster-based routing protocol is always a hot research area in wireless sensor networks. Classical LEACH protocol has many advantages in energy efficiency, data aggregation and so on, so it is widely used until now. In this paper, based on the LEACH protocol, we propose a new distance-based clustering routing protocol, LEACH-SC (LEACH-selective cluster).In LEACH-SC, a new method is used to choose cluster heads, i.e. an ordinary node A will choose a clusterhead which is the closest to the center point between A and the sink. The simulation results show that compared with LEACH, LEACH-SC protocol can greatly reduce the overall network energy consumption, balance the energy consumption among the sensors and extend the lifetime of the network. ©2010 IEEE. © 2010 IEEE.
