概要	We propose a scheme for reducing the energy consumption of data gathering wireless sensor networks with unevenly distributed nodes, and thereby prolong the service life of networks. The proposed scheme selects multi-sink destinations based on the residual power reduction rate of nearby nodes, and curtails routing via the load-concentrated nodes after detecting these nodes based on their packet reception state. Energy consumption on the high traffic load nodes is reduced by this load balancing among relay nodes, which balances loads on load-concentrated nodes and nodes near sinks. Comparing our proposed scheme with a conventional approach by computer simulation, we prove that our method uses less energy to run topologies where load-concentrated nodes are present, and thus prolongs the service life of the network.
