Indoor localization during installations using wifi
نویسنده
چکیده
The position of a participant during an installation is a valuable data. One may want to start some sample when someone cross a line or stop the music automatically whenever there is nobody inside the main area. GPS is a good solution for localization, but it usually loses its capabilities inside buildings. This paper discuss the use of Wi-Fi signal strength during an installation as an alternative to GPS.

Indoor WiFi Localization with a Dense Fingerprint Model
WiFi-based localization is a popular approach for positioning a WiFi-enabled device in an indoor environment. Most implementations rely on querying fingerprint databases, created by stop and go sampling of WiFi signals at discrete locations used as reference points. In this paper, we propose an approach for rapid creation of a dense WiFi fingerprint database using a human operated ambulatory ba...
متن کاملA Robust Crowdsourcing-Based Indoor Localization System
WiFi fingerprinting-based indoor localization has been widely used due to its simplicity and can be implemented on the smartphones. The major drawback of WiFi fingerprinting is that the radio map construction is very labor-intensive and time-consuming. Another drawback of WiFi fingerprinting is the Received Signal Strength (RSS) variance problem, caused by environmental changes and device diver...
متن کاملIndoor Localization by Signal Fusion
Indoor localization based on image matching faces the challenges of clustering large amounts of images to build a reference database, costly query when the database is large and indistinctive image features in buildings with unified decoration style. We propose a novel indoor localization algorithm using smartphones where WiFi, orientation and visual signals are fused together to improve the lo...
متن کاملDoes BTLE measure up against WiFi? A comparison of indoor location performance
Bluetooth low energy(BTLE) is an emerging lowpower wireless communication technology which is expected to be of great potential in the next few years. In this paper, we propose several empirical propagation models for BTLE in different conditions: indoor/outdoor, line-of-sight (LOS) / non-line-ofsight (NLOS). Then we compare the propagation characteristics between BTLE and WiFi. It is demonstra...
متن کاملWiFi Based Indoor Localization System by Using Weighted Path Loss and Extreme Learning Machine
The methodology of our WiFi based indoor localization system is built upon passive cooperation of occupants only which does not interrupt the daily lives of them. Instead of modifying the hardware or software of occupants’ mobile devices, we upgrade the software of the existing commercial WiFi access points (APs) in the indoor environment to WiFi sniffers, which can detect the received signal s...
