Modelling and simulation of the interference behaviour in industrial wireless communication

Several wireless communication systems operating in parallel are typical for industrial applications. These systems have to be coexistent in order to fulfil all their application communication requirements. Ensuring this coexistence is called coexistence management. In this contribution we investigate modelling and simulation of the interference behaviour of the coexistence plant for an automated coexistence management with control engineering considerations. For modelling the time behaviour of message transmission we use timed Petri-nets in max - plus algebra. For that, we formulate an analytical model for evaluation of the coexistence behaviour. For validation of the model we use an industry-oriented hardware-in-the-loop setup with WiFi-technology as test system.
