Abstract :
In wardriving, test devices in moving vehicles measure received signal strengths (RSSs) from nearby base stations (BSs) and record them with location information, which is a key component in localization technologies. In this article, the authors analyze the wardriving data in real WCDMA, GSM, and Wi-Fi networks and describe how signal dragging degrades their performance. They also propose three methods for postprocessing wardriving data to filter out any outdated BS information, thereby mitigating this effect.
