碩士 === 淡江大學 === 資訊工程學系碩士班 === 106 === In this paper, we explore the target-barrier coverage in a wireless sensing network with static and mobile sensors. The target defense line is to form a surrounding defense line within the limits of the target, thereby detecting whether an object invades the target. In this paper, we set two kinds of peripheral distance limits for the target defense line, namely boundlow and boundup. Boundlow refers to the member of the defensive line constructed by the center point of the target. It must have a distance above the boundlow. The boundup refers to the member of the defensive line constructed by the center point of the target, and must not exceed the boundup distance. The defensive line coverage of the target with this distance limit is suitable for many scenarios, such as monitoring of the battlefield environment, detecting whether there are intruders in the periphery, or monitoring in the ecological protection zone at important military positions. Since the target defense line has a boundlow distance limit, when the defense line detects an intruder, the target can have enough time to react. In this article, we explored how to use a less mobile sensor with a static sensor to construct a target defense line. Through experimental simulation, we can verify that our proposed method has better network survival time.
