Research of energy-efficiency algorithm based on on-demand load balancing for wireless sensor networks

Wireless sensor networks in the cluster algorithm use multi-hop style of communication, close to the sink node of the cluster head node transmit a lot of data which led to excessive energy consumption, the node is easily failure, finally network partitioning. This paper introduces the concept of the node load index and presents a demand-based load balancing algorithm for wireless sensor networks for energy-efficiency. Pairs of nodes are improving the self-energy, optimizing the energy structure of the network. Simulation results show that, compared with the LEACH algorithm, the new algorithm is effective. It is to effectively balance the network energy consumption, improve the network life-cycle and ensure the communication quality.
