An energy-balanced distributed clustering protocol for wireless sensor networks

This paper proposes a novel clustering protocol which divides the overall network to virtual circles with variable radius and uses a novel approach for intra-cluster communications. In this protocol the radius of virtual circles and the size of clusters would be increased by the distance to base station (BS) and, therefore, the size of clusters are different. In each cluster, the leader nodes are responsible for aggregating data from ordinary nodes and sending them to cluster heads. Simulation results demonstrate that proposed protocol increases the network lifetime over 73% and 21% comparing to LEACH and DSBCA protocols.
