%X WSNs have many features, such as a majority of nodes, short communication range and limited energy. This paper presented a query gain routing QGR algorithm and routing-based load balancing mechanism. QGR algorithm maintained routing information through query gain matrix, and chose routing nodes according to the successful historic query records, while the routing-based load balancing mechanism stored nodes' energy information during the process of query routing. Simulation results show that QGR algorithm achieves relatively high query hit rate with low energy consumption, and routing-based load balancing mechanism further reduces energy consumption in terms of load transfer efficiency of QGR.
