With the continuous development of intelligent terminal technology, the demand for Location Based Services (LBS) is also increased. Thus, the research of indoor positioning technology is of great significance. Based on the characteristic of the mobile positioning terminal and the presence of the AP in the indoor positioning environment, the indoor location fingerprint algorithm is the most feasible...
To improve the accuracy of electromagnetic (EM) indoor positioning system, there are still two challenges in the system. Firstly, the distance in real (Geometric) coordinates and EM coordinates is not linear. Secondly, the Non-linearity is varied in different regions which can result in great difficulties in proposing an error correction to integrally improve the accuracy of the EM indoor positioning...
Indoor location (IL) using received signal strength (RSS) is receiving much attention, mainly due to its ease of use in deployed IEEE 802.11b (Wi-Fi) wireless networks. Fingerprinting is the most widely used technique. It consists of estimating position by comparison of a set of RSS measurements, made by the mobile device, with a database of RSS measurements whose locations are known. However, the...
TOA-based methods represent an interesting alternative to overcome important constraints of the existing fingerprinting solutions to locate WiFi devices indoors, especially in terms of accuracy, stability and quick deployment. However, in some situations the scalability of TOA-based methods to large number of users is expected to be degraded because of the traffic generated by the positioning process...
