Abstract
In this paper, a positioning system based on smart space wireless sensor network platform is designed and a positioning method of RSSI-based wireless sensor network is studied. The intelligent wheelchair as a blind node in the smart space positioning system is used to collects adjacent the reference node coordinates and RSSI value. The blind node coordinates can be calculated by CC2431 location engine to achieve a wireless location. The test results show that: positioning error of the node is about 1 meter, so it has the potential to satisfy the application of the intelligent wheelchair indoor positioning.
