Abstract
The quality of location-based services (LBS) services depends on the available accuracy of the used positioning method. There are generally several ones for wireless networks. The more accurate methods are way more expensive to implement. On the contrary, there are methods with lower accuracy and much lower costs as well. Received signal strength (RSS) method, which is described below, belongs to the latter case. The purpose of this paper is to describe a performance of adaptive geometric algorithm (AGA)for estimation of mobile station position in multipath environment. The algorithm is an improved version of basic geometric algorithm and it is compared to it as well as to Standard Least Squares method. The properties of the proposed algorithm are evaluated in a simulation and experimental scenario. Both scenarios are implemented in typical multipath conditions, which are crucial in wireless communication. Key words: Adaptive geometric algorithm, mobile positioning, received signal strength method, wireless networks.
