碩士 === 國立臺南大學 === 資訊工程學系碩士班 === 102 === In the thesis, we focus on discussing how to build wireless sensor network by usage of mobile sensors, and how to provide the characteristic of trap coverage which performs a sufficient coverage model for users in many applications in mobile sensor network. The purpose of target tracking with the characteristic of trap coverage can be reached based on trap adjustment and the mobility of mobile sensors. The advantage of building wireless sensor networks by usage of mobile sensors is mainly that the network topology is able to be reconfigured and obtain a better performance level due to its mobility. Because of the trap under trap coverage, target will be presumably undetected. It causes a serious error or fail for target tracking. However, this characteristic of trap coverage is contrary to mobile target detection and tracking. In the thesis, the advantages of trap coverage can be retained and the performance in target tracking and detection can be improved. Experimental results show the proposed method can be efficiently reduced target missing time through the mobile sensor movements in mobile sensor networks based on our simulation and analysis.
