碩士 === 國立中興大學 === 電機工程學系所 === 101 === In recent years, Localization is one of key technologies in wireless sensor networks(WSNs) . the sensor units of the wireless sensor network have made tremendous progress, and it has been used in a wide variety of applications. Considering the shortages of precision on classic multidimensional scaling anchor-free localization algorithm, new collaborative pedestrian positioning algorithm based on the history information are propose. we consider the history information and MDS-Minimum、MDS-Average algorithm are modify algorithm of the Floyd. They calculated the angle based on historical information, speculated that the next distance Dij. MDS-Minimum will take the minimum shortest path, MDS-Average is average path. Through theoretical analysis and simulations, our simulation results show that MDS-Minimum and MDS-Average algorithm improves the accurancy of node localization significantly.
