Improved human integration, machine connectivity and decentralized collaborative control systems play an important role in making production systems more flexible. Cyber-Physical Systems for machine control, mobile HMI or SCADA systems are increasingly connected via Internet-based technologies and must also be protected by this open communication technology. Based on a STRIDE analysis, the paper presents proposals on how to secure data exchange between CPS as well as between CPS and mobile HMI using IoT communication, whereby the practicability plays an important role. First results show that the concepts are feasible and are currently undergoing prototypical testing. Future work will focus on the detailed evaluation with respect to communication performance and the determination of the code overhead of the presented solutions.

This paper presents a novel decentralized control and communication system targeting diverse set of Material Handling Systems. It is an open platform and based on modular Industrial Device collaboration. The relation of proposed system with Industrial Internet of Things, which have relatively relaxed real time requirements, is also given.

Bluetooth networks can be constructed as piconets or scatternets depending on the number of nodes in the network, Although piconet construction is a well-defined process specified in Bluetooth standards, scatternet formation policies and algorithms are not well specified. Among many solution proposals for this problem, only a few of them focus on efficient usage of bandwidth in the resulting scatternets. In this paper, we propose a distributed algorithm for the scatternet formation problem that dynamically constructs and maintains a scatternet based on estimated traffic flow rates between nodes. The algorithm is adaptive to changes and maintains a constructed scatternet for bandwidth-efficiency when nodes come and go or when traffic flow rates change. Based on simulations, the paper also presents the improvements in bandwidth-efficiency and reduction in energy consumption provided by the proposed algorithm
