Received Signal Strength Indicator is an indication of power level being received by a wireless device. This parameter for Wireless Fidelity has never been standardized, so any manufacturer implements it measuring as best they know how. This is a problem because different scenarios can be found based in several elements like: the particular Wireless Fidelity Network Interface Card implementation, the driver, the operating system and software monitoring implementation. This makes the utilization of the Received Signal Strength Indicator to implement higher level functions in wireless networks (like roaming management or localization of terminals) be a headache in realistic scenarios. This heterogeneity of devices, drivers… makes that the application of the Received Signal Strength Indicator be not general. In this paper we present the comparison of our new model of Received Signal Strength Indicator prediction in several realistic and heterogeneous scenarios. The experimental results indicate that we obtain in general, better results than the other models.
