The Influence of Inter-Domain Mobility on Message Stream Response Time in Wired/Wireless Profibus-Based Networks

Abstract

In previous works we have proposed a hybrid wired/wireless PROFIBUS solution where the interconnection between the heterogeneous media was accomplished through bridge-like devices with wireless stations being able to move between different wireless cells. Additionally, we had also proposed a worst-case timing analysis assuming that stations were stationary. In this paper we advance these previous works by proposing a worst-case timing analysis for the system's message streams considering the effect of inter-cell mobility.
