“…Most of the previous works are focused on real-time [27, 35-39, 42, 45] and other performance criteria [40,41,43,44,46,47]. As they corroborate, the standard scheduling algorithms for distributed systems cannot satisfy the requirements in CPS environments.…”

“…In addition, the independent functioning of the nodes which could have their own workload makes those schemes difficult to apply in practice. The current proposals for CPS environments provide different contributions and aim to include additional methods to overcome these issues such as different criticality level of the tasks [37][38][39]47], mathematical techniques [27,35,44], agents [41], and control mechanisms [46]. Other works deal with network and physical dynamic issues [36,40,42,43].…”

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Highlights  A computation model to distribute the application workload over the CPS is proposed.  The scheduling method dynamically shares the tasks among the computing nodes of the CPS.  This approach facilitates the networking and integration of heterogeneous computer devices.

“…As physical equipment, their queues, and the incoming job traffic are interconnected in the CPSF, every station will have the ability to take local decisions with global shop-floor information. This approach has already been considered by Liu et al (2014) as they proposed to use a dynamic multi-priority sequencing procedure for node task sequencing in a CPSF.…”

Meeting Real-Time Constraint of Spectrum Management in TV Black-Space Access

The TV set feedback feature standardized in the next generation TV system, ATSC 3.0, would enable opportunistic access of active TV channels in future Cognitive Radio Networks. This new dynamic spectrum access approach is named as black-space access, as it is complementary of current TV white space, which stands for inactive TV channels. TV black-space access can significantly increase the available spectrum of Cognitive Radio Networks in populated urban markets, where spectrum shortage is most severe while TV whitespace is very limited. However, to enable TV black-space access, secondary user has to evacuate a TV channel in a timely manner when TV user comes in. Such strict real-time constraint is an unique challenge of spectrum management infrastructure of Cognitive Radio Networks. In this paper, the real-time performance of spectrum management with regard to the degree of centralization of infrastructure is modeled and tested. Based on collected empirical network latency and database response time, we analyze the average evacuation time under four structures of spectrum management infrastructure: fully distribution, city-wide centralization, national-wide centralization, and semi-national centralization. The results show that national wide centralization may not meet the real-time requirement, while semi-national centralization that use multiple co-located independent spectrum manager can achieve real-time performance while keep most of the operational advantage of fully centralized structure.
