Energy Balance Algorithm based on LEACH

For the weakness in the cluster head election of LEACH algorithm in Wireless Sensor Network(WSN),We propose an improved algorithm based on LEACH from point of view that regional energy balance of the network. Proposed algorithm can make the node that has more remaining energy to serve as the cluster head(CH). Meanwhile, when the sensor nodes choose the CHs, it will depend on not only the distance between the sensor nodes and the CHs, but also the capacity of the CHs to join. Simulation results show that the proposed algorithm is effective in balancing the network energy consumption and prolonging the network lifetime.
