Research on the Key Technology and Method of Indoor Localization Based on WLAN

Zhe Chen, Yanxiang He, and Wenxue Yang
Abstract—With the widespread use of wireless networks and development of pervasive computing technology, location based services (LBS) have attracted more and more attention and shown great energy in many applications, such as emergency, moving target tracking and customized information delivery. Localization technology is a prerequisite and key to for LBS to be implemented. Common Localization methods include TOA (Time of Arrival) and AOA (Angle of Arrival). In this paper proposed TOA&AOA composite positioning method combines both of their features, reduces the required positioning wireless APs (Access Points), simplifies the location environment, improves the efficiency of locating. This paper through theoretical analysis and simulation comparison proves that the composite positioning accuracy is within acceptable range.

Index Terms—Location based services (LBS), wireless local area network (WLAN), time of arrival (TOA), angle of arrival (AOA), measurement error
