| Summary: | 碩士 === 淡江大學 === 資訊工程學系碩士班 === 99 === In recent years, for the prevailing of WSNs, the function of Localization tracking had widely in environmental observation. Such as: military, mining, personnel monitoring ... and so on. The equipment used in the thesis is IEEE802.15.4/Zigbee of module which is low-power and low cost. By using the RSSI localization algorithm, user can know the localization of all the Nodes.
In this thesis, using GPS to get the latitude and longitude coordinates and translate to the format of coordinates of Zigbee. It will automatically update the reference node, as a reference coordinate of blind node, users can know the coordinates of all existing nodes. In this thesis, we find a better position layout of the reference nodes, so blind node calculate the better accurate coordinate. We proposed two methods to expand the utilized range and can also be used for emergency system.
