Indoor signal attenuation assessment via fuzzy logic

This work focuses on the analysis of signal′s attenuation in indoor environments using a fuzzy logic approach based on the Shadowing Signal Propagation Model (SSPM). The SSPM allows the characterization of the attenuation caused by the environment through the ? parameter present in this model. In addition to this, the Fuzzy Logic provides a form of approximate reasoning that allows the treatment of problems with incomplete, vague and imprecise information. Also, it offers a simple way to obtain a possible solution for a problem using the heuristic knowledge about a particular situation. The results show that the methodology produced satisfactory results, close to the ones yielded by experimental methods.
