The accuracy of Received Signal Strength (RSS)-based positioning methods is highly variable due to its dependence on various varying parameters such as the wireless environment, topology of the network, propagation model utilized etc. In this paper, simulated data was analyzed to examine the effect distances and number of BSs used has on positioning accuracy based on four RSS-based geometric positioning methods. There is relatively varying differences that the topologies of the network have on the accuracy of the positioning algorithms. The RSS-based Geometric algorithms considered include the Centre of Gravity, the Centre of Trilateration, the Least Square and the Trilateration algorithms.
