Real-Time Communications over Hybrid Wired/Wireless PROFIBUS-based Networks

Abstract:
There is an enormous eagerness to use wireless communications in the factory-floor, where fieldbus networks play a major role. PROFIBUS is an international standard (IEC 61158) with some hundreds of thousands of installations world-wide. However it does not include any wireless capabilities. In this paper we propose a hybrid wired/wireless PROFIBUS solution where most of the design options are made in order to guarantee the proper real-time behaviour of the overall network. We address the timing unpredictability problems placed by the co-existence of heterogeneous transmission media in the same network. Moreover, we propose a novel solution to provide inter-cell mobility to PROFIBUS wireless nodes.
