ESF Exchange Grant – Final Report Efficient Signal Strength Sampling for 802.11-based Indoor Positioning Systems
Using 802.11 concurrently for communications and positioning is problematic, especially for real-time communications (e.g., VoIP, video conferencing). Periodical scanning for measuring the signal strength interrupts the data flow. Reducing the scan frequency is also no option because it hurts the position accuracy. For this reason, we need an adaptive technique to mitigate this problem. This wo...
متن کاملΠ8: Indoor Positioning System using WLAN Received Signal Strength Measurements
In this deliverable we provide the details of building an indoor positioning system using WLAN Received Signal Strength (RSS) fingerprints. The positioning system has been deployed at the premises of KIOS Research Center and follows a terminal-based-network-assisted architecture. In our case, users that carry a terminal (Tablet PC) are able to self-locate and positioning is performed entirely o...
متن کاملModeling of WLAN Beacon Signal Strength Measured in an Indoor Environment
In the fourth generation wireless networks, it is believed that wireless LANs (WLANs) will interwork with cellular systems to provide fast speed data services. The integration of WLANs and cellular systems calls for a careful design of handover decisions. In WLANs, the received signal strength (RSS) is used for handover decision, thus a thorough understanding of the characteristics of the RSS o...
متن کاملA Robust Received Signal Strength Based Positioning Algorithm for Indoor Environments
Localization for mobile wireless sensor networks has been intensively studied in recent years due to its many applications in mobile networking as well as various public safety problems. However, the complexity of indoor radio propagation, especially when considering mobile users, makes indoor positioning a challenging task. This is mainly due to the severe multipath phenomenon where multiple c...
متن کاملReceived Signal Strength Database Interpolation by Kriging for a Wi-Fi Indoor Positioning System
The main approach for a Wi-Fi indoor positioning system is based on the received signal strength (RSS) measurements, and the fingerprinting method is utilized to determine the user position by matching the RSS values with the pre-surveyed RSS database. To build a RSS fingerprint database is essential for an RSS based indoor positioning system, and building such a RSS fingerprint database requir...
