Barsocchi P., Chessa S. Adaptive RSSI-based localization method in wireless sensor networks. Technical report, 2010.
Received Signal Strength Indicator (RSSI) is not suitable for fine-grained indoor applications because of temporal variations in wireless fading events. This paper presents a simple and robust mechanism to dynamically calibrate the signal propagation model parameters following the wireless channel variations. The proposed method enhances the accuracy of RSSIbased localization techniques without the extensive, accurate and time-consuming human interventions. The contribution of this proposal are consists in the implementation's easiness and its excellent output performance, compared with the commonly static calibration procedures.
