Executive Summary

Many sensor network applications demand tightly-bounded object detection quality. To meet such stringent requirements, the authors develop three sensing scheduling protocols to guarantee worst-case detection quality in a sensor network while reducing sensing power consumption. The protocols emulate a line sweeping through all points in the sensing field periodically. Nodes wake up when the sweeping line comes close, and then go to sleep when the line moves forward. In this way, any object can be detected within a certain period. The authors prove the correctness of the protocols and evaluate their performances by theoretical analyses and simulation.
