At the same time keep-alive-messages are excessively used in these networks to test channel characteristics. This work proposes an approach to reduce bandwidth usage in critical industrial applications, by exploiting channel quality data from 5G. Thereby, the information about the channel is gained from channel state information (CSI) and the radio resource control (RRC) state. This work combines the CSI with the RRC state to determine whether a wireless node is connected. Subsequently, the connection information is exposed towards the application server via the network exposure function (NEF) of the 5G core network and to the mobile application by the UE. Since the CSI and RRC state are always present, this results in a net bandwidth reduction on the air interface of approximately 1.65 Mbps in the examined reference use case in contrast to the standard keep-alive mechanism.","PeriodicalId":312498,"journal":{"name":"2021 26th IEEE International Conference on Emerging Technologies and Factory Automation (ETFA )","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117291922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such eco-systems, the secure sharing of information, data and equipment challenges the access control needs to be application agnostic. Furthermore, it needs fine-grained access policies including means for abstraction to ease administration, and support for delegated authorization in Service-Oriented Architecture (SOA) based systems. In this paper, we explore the use of delegated access using OAuth 2.0 with Attribute-Based Access Control (ABAC) for the collaborative sharing of equipment at construction sites. In particular, we investigate the use of contextual attributes to capture the dynamic aspects, such as location and urgency, in the booking of construction lifts. Through this study, we propose a solution based on the IoT Application-scoped Access Control as a Service (IAACaaS) architecture model combined with NIST Next Generation Access Control (NGAC). We present an architecture for a general Identity and Access Management (IAM) system for the construction industry, and provide a design and guide for implementation of this architecture in terms how key functionalities should be captured as reusable micro-services. Moreover, we describe how these micro-services can be combined to make the system a general and reusable solution providing access control for collaborative sharing of data, information and equipment at construction sites.","PeriodicalId":312498,"journal":{"name":"2021 26th IEEE International Conference on Emerging Technologies and Factory Automation (ETFA )","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115413227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper investigates (i) how to integrate local engineering views with Common Concepts (CCs) and using them as a defined taxonomy for modeling a network of engineering concepts; (ii) how to build an engineering network graph for visualisation and analysis considering discipline-specific needs. We motivate a method to support CPPS engineering organisations to integrate their heterogeneous data using CCs.

Moreover, cyclic executives are hardly addressed in contemporary text books, if at all. Cyclic executives are still in use, however, and there is therefore a need for analysis techniques for these executives. In this document, we consider two basic cyclic executives, i.e. a single-rate AFAP (as fast as possible) and a single-rate time-driven AFAP cyclic executive, scheduling a given sequence of independent hard real-time polling tasks in a single-processor system. We present exact analysis for both cyclic executives and discuss their relative strengths and weaknesses in terms of jitter, energy efficiency, and schedulability. Unlike existing approaches, which typically take periodic tasks as a starting point for cyclic executives and focus on schedulability of tasks, we take the schedulability of the system as a starting point, i.e. whether or not the system meets its deadlines. In particular, we do not assume periods and deadlines for tasks.","PeriodicalId":312498,"journal":{"name":"2021 26th IEEE International Conference on Emerging Technologies and Factory Automation (ETFA )","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125488824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its principle is to mend the barrier gaps by rotating the heterogeneous sensors, to achieve the optimization objectives of maximum coverage rate, minimum gap rate.

The TSN profile for industrial automation (IEC/IEEE 60802 standard) defines specific options to favor reliability and reconfigurability. Nevertheless, there are multiple possible options for scheduling to guarantee determinism. Today, the scheduling standards in TSN can be categorized according to the implemented communication paradigm: asynchronous or synchronous. This paradigm is of utmost importance to quantify the synchronization need and the reconfigurability effort. The main contribution of this work is the specification of an asynchronous TSN-compliant network for Industry 4.0, FactoRing, that bridges the gap between both paradigms to guarantee low bounded jitters and latencies, without the need of synchronization and complex network planning. Moreover, FactoRing supports ring-based topologies to significantly reduce installation wiring and costs. In this paper, we first present the main industry 4.0 requirements and assess the ability of recommended TSN mechanisms for industrial automation versus such requirements. Afterwards, we detail the main features of Factoring including QoS, reliability and reconfiguration management. Finally, preliminary results on performance metrics like jitters, latencies and buffer usage are discussed and the first conclusions on the promises of Factoring to meet Industry 4.0 requirements are derived.","PeriodicalId":312498,"journal":{"name":"2021 26th IEEE International Conference on Emerging Technologies and Factory Automation (ETFA )","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127825941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
