An Energy-Efficient In-network Join for Event Detection in Sensor Networks

For energy-efficient event-detection in sensor networks, we can perform an in-network join of two relations, i.e., a sensor table and a condition table, where a condition table is a set of tuples each of which contains condition information about a certain event. In this paper, we propose an in-network method for efficient join of a sensor table and a condition table. We also show through performance experiments that the proposed method works better than the existing method.
