Recently, the fingerprint-based wireless local area network (WLAN) positioning has gained significant interest. A probability distribution-aided indoor positioning algorithm based on the affinity propagation clustering is proposed. Different from the conventional fingerprint-based WLAN positioning algorithms, the paper first utilizes the affinity propagation clustering to minimize the searching...

WiFi fingerprinting is a localization technology that leverages existing wireless infrastructures in indoor settings. Although fingerprints can be calibrated to a high degree of accuracy, the precision of such maps changes due to environment changes. We propose a system that automatically re-calibrates the WiFi fingerprint maps using a mobile robot. As the robot traverses the building, it encou...

With the development of Wireless Local Area Networks(WLANs), people are interested in developing the location-based services for WLAN users, especially in an indoor environment. The core technology of location-based services is the location-sensing technology. In this paper, we present a location-sensing method which is based on the location fingerprinting approach for WLAN in an indoor environ...

Fingerprint-based indoor positioning uses pattern recognition algorithms (PRAs) to estimate the users’ locations in wireless local area network environments, where satellite-based methods cannot work properly. Traditionally, training phase of PRA is separately conducted for <tex-math notat...

Producing IEEE 802.15.4 PHY-frames reliably accepted by some digital radio receivers, but rejected by others—depending on the receiver chip’s make and model—has strong implications for wireless security. Attackers could target specific receivers by crafting “shaped charges,” attack frames that appear valid to the intended target and are ignored by all other recipients. By transmitting in the un...

The effectiveness of Location Based Systems depends on the correct location of users and mobile devices. While the outdoor location can be easily calculated, using technologies such as GPS (Global Positioning System), it is more difficult to obtain when the location scenario is an indoor environment. Several technologies and location techniques can be used in this field. One of these techniques...

Abstract. Received Signal Strength (RSS) is one of the most useful information used for location estimation in Wireless LAN (WLAN). Most of the proposed WLAN positioning systems obtain RSS from either the Access Point or from the Mobile Device, but there are few researches that make use of the RSS obtained from both Access Points and Mobile Devices to perform location estimation. In this paper,...

This paper concerns indoor location determination by using existing WLAN infrastructures and WLAN enabled mobile devices. The location fingerprinting technique performs localization by first constructing a radio map of signal strengths from nearby access points. The radio map is subsequently searched using a classification algorithm to determine a location estimate. This paper addresses two dis...

Received Signal Strength (RSS) fingerprinting is an attractive solution for indoor positioning using WLAN due to the wide availability of WLAN Access Points (AP) and the ease of monitoring RSS measurements on WLAN-enabled mobile devices. Fingerprinting systems rely on a radiomap collected with a reference device inside the localization area, however a major limitation is that the quality of the...
