![]() ![]() In this paper we address the goal of achieving higher throughput capacity in multi-hop wireless ad hoc networks than estimated by capacity scaling laws of. We also show its applicability to indoor localization service, by observing how it can be used in a recent high impact paper and improving another paper also published in a high impact journal. We present a new RSSI estimation model that improves other recently published methods and shows that it can be used, in contrast with those other techniques, to a wide range of current wireless terminals and real world scenarios. That is, its long term stability can be estimated. Recently a high impact paper has formally shown that RSSI of laboratory radio signal in WiFi always reverts to its mean. Moreover, every wireless terminal has its own way to provide RSSI. But its high long term variability (volatility) makes its high precision estimation be impossible, complicating its applicability. Traditionally, it has been used to implement wireless services like scanning in handoff. RSSI is a reference magnitude of radio signal strength received by a wireless terminal. The experimental results indicate that we obtain in general, better results than the other models. In this paper we present the comparison of our new model of Received Signal Strength Indicator prediction in several realistic and heterogeneous scenarios. This heterogeneity of devices, drivers… makes that the application of the Received Signal Strength Indicator be not general. 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 is a problem because different scenarios can be found based in several elements like: the particular Wireless Fidelity Network Interface implementation, the driver, the operating system and software monitoring implementation. This parameter for Wireless Fidelity has never been standardized, so any manufacturer implements it measuring as he knows better doing. Received Signal Strength Indicator is an indication of power level being received by a wireless device. ![]()
