碩士 === 國立高雄應用科技大學 === 電子工程系碩士班 === 104 === In Wireless Sensor Networks, the precision of sensor nodes localization will directly affect to perform of WSNs in almost of applications. Therefore, localization problem is a very important work. Localization algorithm will help the network know about the position of unknown sensor nodes based on the location of anchors. Some heuristic optimization algorithms are being proposed and succeeded in applying to solve localization problems in Wireless Sensor Networks. In this context, the performance of these heuristic optimization algorithms in solving localization problem of WSNs and nonlinear functions in both of accuracy and execution time will be compared. An improvement in localization algorithm call Extended Localization Algorithm (ELA) also will be proposed to enhance the number of a node can be localized. This improvement is really potential to extend and apply in many problems of WSN that is related to localization algorithms.
