A Sampling-Based Approach to Optimizing Top-k Queries in Sensor Networks
ICDE, pp. 68-68, 2006.
Wireless sensor networks generate a vast amount of data. This data, however, must be sparingly extracted to conserve energy, usually the most precious resource in battery-powered sensors. When approximation is acceptable, a model-driven approach to query processing is effective in saving energy by avoiding contacting nodes whose values ca...More
