Location awareness is one of the most important information that an individual looks for, both in an outdoor and indoor environment. One of the primary location determination techniques is the Global Positioning system, though this system provides a good accuracy in an outdoor environment, its accuracy decreases in densely populated areas and in an indoor environment a GPS system ceases to provide location information since the satellite signal cannot permeate through the roof and the walls. Various location estimation techniques have been proposed for location estimation in an indoor environment, some utilizing the signal strength of a wifi transmitter, while others using the time of arrival of a signal. In an indoor environment location can be estimated using either of the techniques or by using a hybrid approach. In this paper I will study different algorithms to determine which algorithm is the best approach for indoor location determination is.
