Abstract

Telematics is regarded as the technology to enhance and make everyday-driving experience more comfortable and safer. An essential part of the telematics is navigation and it is based on GPS combined with map-matching and/or MEMS DR as the choice of positioning technology. However, GPS cannot supply position information continuously in case of poor visibility of satellites. In this paper, we research into techniques of RFID which may be regarded as a portion of USN sensor node in order to measure accurate position information of vehicles regardless of environment condition. RFID tag recognition is tested to verify feasibility of accurate positioning according to the speed of vehicle. We also propose characteristics of the USN sensor node and data format for positioning.
