碩士 === 玄奘大學 === 資訊科學學系碩士班 === 95 === Wireless sensor network has been developing vigorously in recent years and the sensor nodes can communicate with each other without any pre-built network infrastructure. In this kind of network, every node transmits data to the destination via the help of other nodes. For many related research propose methods which need to know the positions of sensor nodes, it makes the localization of nodes very important. Though noise surely causes some inaccuracy in the determination of nodes position, yet most of the proposed localization methods did not take the impact factor of noise into consideration. In this paper, we propose several methods to reduce the position error caused by random noise. Finally, some simulation results are shown and discussed.
