Analysis and Research on Indoor Positioning Method Based on IEEE 802.11

摘要：

Although many outdoor location techniques have been proposed, these techniques are ideal outdoors but they are generally not available indoors. With the increasing use of mobile computing devices and an expansion of Wireless Local Area Networks (WLAN), there is growing interest in an indoor wireless positioning systems based on WLAN infrastructure. This paper proposes a method that is based on IEEE 802.11 and uses the Received Signal Strength (RSS) of WLAN transmissions from/to WLAN Access Points (AP) to determine the position of the mobile target; this paper also gives corresponding positioning algorithm. In the proposed method, the indoor environment is divided into several sub-spaces and a database of signal characteristics is created according to the characteristic point and signal transmission model in different sub-spaces, then we can achieve the purpose of indoor accuracy positioning.
