A spatial extension of TinyDB for wireless sensor networks

The ability to run spatial queries is extremely useful for wireless sensor networks. Spatial query execution has been extensively studied in the context of centralized spatial databases; however because of the energy and bandwidth limitation of sensor nodes these solutions are critical to wireless sensor networks. In this paper, we propose an extension of TinyDB suitable to manage the location of sensor nodes and, hence, able to process besides standard queries, spatial queries as well. The proposal has been implemented and validated.
