Wireless sensor networks represent the next generation of sensing machines and structures. Inherent limited energy resource is the one of the limitations of wireless sensor nodes. In order to distribute the energy dissipated throughout the wireless sensor network, data load of the sensor nodes must be balanced. Clustering is one of the key mechanisms for load balancing. Clustering algorithms may result in some clusters that have more members than other clusters in the network and uneven cluster sizes negatively affect the load balancing in the network.
