College of Mechanical Engineering, Xi’an University of Science and Technology, Xi’an 710054 China
Node location is one of the key technologies in wireless sensor network. RSSI-based location is a hotspot in nowadays. For resolving biggish error in RSSI-based location, the paper presents a new method of location, RSSI-based triangle and centroid location, using triangle and centroid method to reduce the error of RSSI measurement. Simulation experiments prove that this algorithm can obviously improve the location accuracy compared to trilateration.
