Mobile positioning is one of the fastest growing areas for the development of new technologies, services and applications. This paper describes a simple and efficient geometric algorithm using received signal strength measurements extracted from at least three base stations. This method is compared with standard Least Squares method. The simulation results show, that geometric algorithm gives m...

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...

Abstract Location techniques play an important part in wireless sensor network. The received signal strength indicator (RSSI) based localization is a promising technique since it requires relatively low configuration and energy. The received signal strength is mainly influenced by propagation environment in wireless sensor network. So we proposed an indoor mobile location algorithm (IMLA). We f...

Wi-Fi fingerprinting is one of the methods that are widely used to provide Location Based Services (LBS). Gaussian, or a mixture Gaussians, preferred model by for LBS. Nevertheless, Received Signal Strength Intensity (RSSI) histograms skewed, and Gaussian not well suited modeling data when their histogram skewed. In addition, another important characteristic present in RSSI temporal series auto...

In this work, we present an on-board solution for train position tracking that can be used in cases of GPS failures and that does not suffer from the error accumulation problem of Dead Reckoning (DR). It is based on Received Signal Strength (RSS) measured in radio communication systems by several mobile stations having antennas placed on top of different carriages of the train. As the RSS is af...

There are various uses of wireless sensor technology, ranging from medical, to environmental, to military. One possible usage is home security. A wireless sensor network could be used to detect the presence of an intruder. We have investigated the use of Received Signal Strength Indicator (RSSI) values to determine the mobility of an intruder and have found that accurate intruder detection is p...
