The main idea of this project is to compare different approaches using measurement data collected from UAV missions. Tasks –Literature study on approaches for anchor selection –Selection of two approaches for the implementation (optional) References [1] Artemenko, O.; Simon, T.; Mitschele-Thiel, A.; Schulz, D.; Ta, R.S., "Comparison of Anchor Selection algorithms for improvement of position estimation during the Wi-Fi localization process in disaster scenario," Local Computer Networks (LCN), 2012 IEEE 37th Conference on, vol., no., pp.44,49, 22-25 Oct. 2012
