Top-k Query Evaluation in Sensor Networks with the Guaranteed Accuracy of Query Results

Chen, Baichen; Liang, Weifa; Min, Geyong


In many applications of sensor networks including environmental monitoring and surveillance, a large volume of sensed data generated by sensors needs to be either collected at the base station or aggregated within the network to respond to user queries. However, due to the unreliable wireless communication, robust query processing in such networks becomes a great challenge in the design of query evaluation algorithms for some mission-critical tasks. In this paper we propose an adaptive,...[Show more]
