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.

基于测量的载波感应行为估计,用于仿真建模
在制造现场复杂的无线环境中,解决通信延迟问题的一种可行方法是通过系统级模拟器(SLS)预测延迟,并提前通知通信控制系统。为了准确预测延迟,SLS 中的载波感应(CS)模型应包含真实设备的特性。然而,由于 CS 的实现规范通常并不公开,因此很难对其进行精确建模。在这封信中,我们提出了一种利用软件定义无线电模拟产生的、由微波炉发射的电磁噪声来估计 CS 特性的方法,并验证了这种方法的有效性。
