Abstract

In this paper, we propose an efficient ranging protocol based on multiple packets for localization. In order to meet era of ubiquitous computing, there is a growing need for an efficient real-time location system. We assumed that multiple packets are used for ranging and proposed an efficient TWR protocol. For multiple ranging packets, the ranging performance is likely to be degraded by the frequency offset, since the total observation time increases. In the presence of a frequency offset, the ranging performance of the proposed method was analyzed and compared to those of other similar methods. Through simulations, theoretical analysis of the performance is verified.
