基于固定周转时延协议的UWB无线测距方法研究
A Study on the UWB Wireless Ranging Method Based on the Fixed Turnover Delay Protocol
摘要
Abstract
Ultra-Wideband( UWB) technology is considered to be the most suitable for indoor wireless location. TW-TOA(Two Way Time of Arrival) Ranging protocol in IEEE802. 15. 4a is based on the reception of timestamp packets to eliminate the receive-send turnover delay. The turnover delay of the same kind of equipment in the same conditions is always the same,so the fixed turnover ranging method is proposed to reduce the ranging data traffic on both sides. In order to improve the reliability of the Hello frame, the protocol is put forward that Hello packets should be sent based on the stop-wait protocol in the initial positioning stage and when the turnover delay drifts seriously during the positioning. At last,the format of MAC sub-layer,compatible with IEEE802. 15. 4,Hello packet and the ranging response packet with the FoM( Figure of Merit) are given.关键词
