Measurement-based estimation of carrier sense behavior for simulation modeling

Abstract

One possible approach to address communication delay in the complex wireless environment of manufacturing sites is to predict the delay by system-level simulator (SLS) and notify the communication control system in advance. For accurate delay prediction, the carrier sense (CS) model in SLS should incorporate real device characteristics. However, accurate modeling of CS is difficult since its implementation specifications are usually not publicly available. In this letter, we propose a method for estimating CS characteristics using electromagnetic noise generated simulatively by software-defined radio and emitted from a microwave oven and verify the effectiveness of this method.
