Abstract:  

Abstract:  With current domestic vehicles increasing, it is difficult to achieve a reasonable planning, control, monitoring and induction in urban transportation system. This paper puts forward an optimization weighted centered wireless sensor network positioning technology based on Received Signal Strength Indicator(RSSI). Studying and utilizing the ZigBee networking positioning and automotive electronic tags, then the collecting data is got accurate position by using the weighted centered localization optimization algorithm. After many test, this system can be positioned within the error range of 0.5m, shows that the algorithm has the advantages of low resource usage, resources, reliability, realtime and high precision.
