Abstract :
Distributed wireless sensor networks will play an important role in the future. In wireless sensor networks, observers are interested in spatio-temporal information monitored by sensors. It is crucial to design and employ energy-efficient query processing since nodes are battery-powered, and thus their lifetimes are limited. This paper proposed a query source sharing approach to optimizing query processing in multi-sinks sensor network. Firstly, basic query conception is defined. All region queries can be linearly expressed by basic queries. Secondly, a data transfer routing establish method was designed. Energy dissipation can be reduced by sharing same query data in multi-sinks sensor network. Simulation results shows that energy cost can be 25% reduced.
