  • The performance of the rss-based least squares lateration algorithm for indoor localization 

    Authors:Barodi, Lubana
    Publisher and Date:(Kadir Has University, 2019)
    Localization methods have evolved over the years until the invention of the technology of global positioning system (GPS). As the technology developed and seeing that people spend most of their times in indoor environments, the need for indoor localization has arised. For localization in outdoor environments, the GPS works extremely well, but it is useless for indoor localization because the signals from the GPS satellites are too weak to penetrate the buildings. Because of that reason, the indoor ...
