The current and expected evolution in industrial facilities imposes increasing requirements on the deployment of suitable communication systems. Cyber-physical production systems trigger a paradigm shift from centrally controlled manufacturing systems towards decentralized systems of cooperative, networked components. Intelligent manufacturing systems, storage systems, and transport systems operate autonomously and exchange relevant information to ensure a flexible, highly adaptive, and selfoptimizing production process. Such applications need a communication service, which can cope with mobility and environmental dynamics while maintaining real-time service quality. Wireless Mesh Networks (WMNs) form a suitable network structure to provide a flexible communication service. Applications should be able to specify their functional and non-functional end-to-end requirements. The envisioned flexibility and the integration of mobile components require the deployment of a network architecture on top of such WMNs that allows for ad-hoc communication and adapts to the actual environmental conditions. In this talk we argue that applying the concept of fault-tolerance concept throughout the various layers of the architecture constitutes a promising approach. It adopts a feedback control loop that adapts the network to the influence of dynamic effects by deploying resource assessment, resource admission and resource provision. The control loop is combined with proactive measures, which prevent service failures in the time between a fault occurs and is properly handled by the control loop.
