Tuning query performance in mobile sensor databases Vladimir Zadorozhny, Divyasheel Sharma, Prashant Krishnmurthy, and Alexandros Labrinidis   View Paper (PDF)   Return to Session 9. Mobility in agents, sensors and services Abstract In this paper we propose a query-driven approach for tuning the time/energy trade-off in sensor networks with mobile sensors. The tuning factors include re-positioning of mobile sensors and changing their transmission ranges. We propose an algebraic query optimization framework that explores these factors while utilizing collision-free concurrent data transmissions with different degrees of data filtering and aggregation. ©2006 Association for Computing Machinery
