Title: Positioning in Wireless Networks - Non-Cooperative and Cooperative Algorithms


In the last few years, location-awareness has emerged as a key-technology for the future development of mobile, ad-hoc and sensor networks. Thanks to location information several network optimization strategies as well as services can be developed. However, the problem of determining accurate location is still a challenge, especially in multipath radio propagation channels such as those of indoor environments.

In this seminar, we survey on a comprehensive list of application scenarios and describe the fundamentals of the main localization methods (angle-based, fingerprinting and distance-based techniques). Amongst all these methods, we focus on distance-based techniques due to their reliability, accuracy and applicability to different types of technologies, e.g. ultra-wide band (UWB), Bluetooth, Wi-Fi and cellular networks.  We consider non-cooperative and cooperative positioning approaches, analyze their challenges and provide a short description of the state-of-the-art algorithms. A few theoretical results are offered to illustrate the impacts of NLOS channel conditions and inter-nodes cooperation on the location accuracy. Finally, we show the performance of non-parametric positioning algorithms based on simulations as well as real positioning tests with UWB devices.
