Skyline is an important query in many applications such as environment monitoring and industrial controlling. Lots of achievements of skyline query have been made in traditional database. But they can not be used directly to wireless sensor network. In this paper we study continuous skyline query in wireless sensor network and put forward an energy efficient algorithm named ORSSQ. ORSSQ sets up filters in sensor nodes based on optimized routing structure. Filters can prune the sample data that can not be the final skyline result to save energy and prolong network life. Experiments show that ORSSQ has good performance.
