    Efficient Device-to-Device Service Invocation Using Arrowhead Orchestration2020Ingår i: IEEE Internet of Things Journal, ISSN 2327-4662, Vol. 7, nr 1, s. 429-439Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Internet of Things (IoT) enables interaction from real-world physical objects using sensors to the virtual world of computers and the Internet. The use of service-oriented architecture (SOA) is one step in the creation of basic and complex interactions between several sensors and actuators. However, the use of SOA-enabled technologies alone does not meet all requirements of how sensor and actuator systems could be integrated to create distributed monitoring and control applications. The centralized, traditional method of communication in wireless sensor networks via a gateway presents drawbacks that have to be addressed; device-to-cloud communication adds higher latency and higher power consumption and is less robust than the device-to-device (D2D) communication approach. Moreover, all these characteristics reduce the scalability of the network, thus limiting the use of IoT in the industry. In this article, the proposed method utilizes the arrowhead framework orchestration system to generate service composition within a (wireless) network formed by IoT devices. The aim is to achieve efficient D2D service invocation to reduce the drawbacks of today's widely used device-to-cloud approach. The method in this article performs efficient service composition for industrial IoT, including mapping SOA service composition in very small resource-constrained devices using the arrowhead orchestration. The results presented in this article at the service level can increase performance and robustness in fog computing on resource-constrained devices.

    Industrial Frameworks for Internet of Things: A Survey2020Ingår i: IEEE Systems Journal, ISSN 1932-8184, E-ISSN 1937-9234Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    The Internet of Things (IoT) has gained popularity and is increasingly used in large scale deployments for industrial applications. Such deployments rely on the flexibility and scalability of systems and devices. Heterogeneous systems need to be interoperable and work together seamlessly. In order to manage such system of systems, it is important to work with a framework that not only supports the flexible nature of IoT systems but also provides adequate support for industrial requirements, such as real-time and runtime features, architectural approaches, hardware constraints, standardization, industrial support, interoperability, and security. The selection of an appropriate framework results difficult due to the rising number of available frameworks and platforms, which offer different support for the aforementioned requirements. Therefore, this article investigates the features of seven prominent frameworks for the purpose of simplifying the selection of a suitable framework for an industrial application. The aim of this article is to present the recent developments and state-of-the-art of industrial IoT frameworks and provide a technical comparison of their features and characteristics.

    Architectural approach for Autonomous System of Systems Interoperability2019Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    The current technological environment is evolving increasingly fast, and the development of new devices, technologies, and architectures has opened an emergent era where the digital and physical world work together. The implementation and use of systems based on a service-oriented architecture (SOA) in conjunction with the Internet of Things (IoT) and cyberphysical systems (CPS) have been extended during the last decades in numerous scenarios in industry and other domains. However, some of the major barriers to this approach are the lack of interoperability and the amount of engineering effort required for their integration.

     

    The research presented in this thesis targets issues related to digitalization and automation. It is framed by the Industry 4.0 paradigm, which promotes the rise of efficiency and sustainability on industrial production. The interoperability between heterogeneous systems and different domains is one of the main challenges of Industry 4.0. The quest for solutions that help to increase interoperability is an important part of this research.

     

    This thesis proposes a set of architectural design principles and tools in order to reduce engineering effort by means of finding solutions that enable autonomous integration and increase interoperability without human intervention. The research is focused on the IoT field, taking into account resource-constrained devices, system of systems integration, and data models.

     

    A detailed investigation of various interoperability mismatch problems is presented in this thesis. The proposed solution is an adapter system that can aid in the generation of new service consumer interfaces at both compile-time and run-time. The proposed approach requires a new point of view in the service description field that can provide a holistic description of the information required for the generation of consumer interfaces.

    In addition, aspects related to interoperability, such as the multiple IoT frameworks in the current market, naming conventions, syntactic modeling and translation, and security, are also partially analyzed.

     

    On a separate track, service composition in resource-constrained devices

     is analyzed in terms of latency, using the orchestration provided by the Arrowhead Framework.

    Interoperability Mismatch Challenges in Heterogeneous SOA-based Systems2019Konferensbidrag (Refereegranskat)
    Abstract [en]

    In Industry 4.0, systems with a heterogeneous imple-mentation, different architecture, protocols, and semantics have to be integrated into collaborative environments. The interoper-ability between them has become a major challenge in this new ecosystem of the industry, thereby generating several research questions about how to manage the information exchange and collaboration between systems with so vastly different properties.This paper presents a detailed investigation of the different mismatch problems that can happen in the information ex-change in heterogeneous SOA-based environments where the interoperability is crucial. The proposed solution in this paper is an Adapter System that can aid generatation of new service consumer interfaces at both compile-time and run-time. The interfaces are based on Service Contracts, thereby allowing heterogeneous systems to communicate and interchange services.The proposed approach requires a new point of view in the service description field that can provide a holistic description of the information required for creating both run-time and compile-time consumer interfaces.

    Syntactic Translation of Message Payloads Between At Least Partially Equivalent Encodings2019Konferensbidrag (Refereegranskat)
    Abstract [en]

    Recent years have seen a surge of interest in using IoT systems for an increasingly diverse set of applications, with use cases ranging from medicine to mining. Due to the disparate needs of these applications, vendors are adopting a growing number of messaging protocols, encodings and semantics, which result in poor interoperability unless systems are explicitly designed to work together. Key efforts, such as Industry 4.0, put heavy emphasis on being able to compose arbitrary IoT systems to create emergent applications, which makes mitigating this barrier to interoperability a significant objective. In this paper, we present a theoretical method for translating message payloads in transit between endpoints, complementing previous work on protocol translation. The method involves representing and analyzing encoding syntaxes with the aim of identifying the concrete translations that can be performed without risk of syntactic data loss. While the method does not facilitate translation between all possible encodings or semantics, we believe that it could be extended to enable such translation.

    An AAA Solution for Securing Industrial IoT Devices using Next Generation Access Control2018Konferensbidrag (Refereegranskat)
    Abstract [en]

    Industry 4.0 is advancing the use of Internet of Things (IoT) devices in industrial applications, which enablesefficient device-to-device (D2D) communication. However, these devices are often heterogeneous in nature, i.e. from different manufacturers, use different protocols, etc. and adds requirements such as security, interoperability, etc.To address these requirements, the Service-Oriented Architecture-Based (SOA) Arrowhead Framework was previously proposed using the concept of local clouds. These local clouds provide a set of mandatory and support core systems to enable industrial automation applications. One of these mandatory core systems is an Authentication, Authorisationand Accounting (AAA) system, which is used to authenticate and provide access control to the devices in a local cloud. In an industrial context, with multiple stakeholders, the AAA mustsupport fine-grain access control. For example, in a distributed control loop, a controller should only have read access to its sensor such as a flow meter and write access to its actuator, such as a valve. The controller should not have access to anyother information besides what is needed to implement the desired functionality. In this work, an NGAC-based AAA solution to achieve fine-grain service level access control between IoT devices has been proposed and implemented. The solution is presented using a district heating use case.
