Response Time Constrained Top-k Query Evaluation in Sensor Networks

Liang, Weifa; Chen, Baichen; Xu, Jeffrey Y.


Existing solutions for top-k queries in wireless sensor networks mainly focused on energy efficiency and little attention has been paid to the response time to answer a top-k query as well as the relationship between the response time and the network lifetime. In this paper we address this issue explicitly by studying the top-k query problem in sensor networks with the response time constraint. We aim at finding an energy-efficient routing tree and devising an evaluation algorithm for top-k...[Show more]
