Abstract: Accurate indoor localization has long been an objective of the ubiquitous computing research community. Among the various data types used for localization, WLAN-based localization is considered to be one of the most popular methods as it does not require any additional hardware and it is available in most wireless networks. The collection of WLAN signals is usually done via wardriving – an act of searching for Wi-Fi network by a person in a moving vehicle. However, the use of wardriving data can be harmful if they are not processed carefully. It is observed, in particular, that signal pattern obtained from wardriving tends to contain more signals from reference points positioned opposite the terminal’s moving direction than signals from reference points positioned in the forward. This phenomenon is known as signal dragging.
