    Configuration Service in Cloud based Automation Systems2016In: IECON Proceedings (Industrial Electronics Conference), Piscataway, NJ: IEEE Computer Society, 2016, p. 5238-5245, article id 7793489Conference paper (Refereed)
    Abstract [en]

    Current challenges in production automation requires the involvement of new technologies like Internet of Things (IoT), Systems of Systems and local automation clouds. The objective of this paper is to address one of the challenges involved in establishing and managing a cloud based automation system. Three key capabilities have been identified as required to create the expected benefits of local automation clouds; 1) capturing of plant design 2) capturing and distributing configuration and deployment information 3) coordinating information exchange.

    This paper addresses the capturing and distribution of configuration and deployment information. For this purpose a system service is proposed, the ConfigurationStore, following the principles of the Arrowhead Framework. The service is accompanied by a deployment methodology and a bootstrapping procedure. These are discussed for several types of automation technology, e.g. controllers, sensors, actuators. A qualitative evaluation of the proposed approach is made for four use cases; Building automation, Manufacturing automation, Process automation and IoT devices. Concluding the usability for large-scale deployment and configuration of Industrial Internet of Things.

    Translation Error Handling for Multi-Protocol SOA Systems2015In: Proceedings of 2015 IEEE 20th International Conference on Emerging Technologies & Factory Automation (ETFA 2015): Luxembourg, 8-11 Sept. 2015, Piscataway, NJ: IEEE Communications Society, 2015, article id 7301473Conference paper (Refereed)
    Abstract [en]

    The IoT research area has evolved to incorporate aplethora of messaging protocol standards, both existing and new,emerging as preferred communications means. The variety ofprotocols and technologies enable IoT to be used in manyapplication scenarios. However, the use of incompatiblecommunication protocols also creates vertical silos and reducesinteroperability between vendors and technology platformproviders. In many applications, it is important that maximuminteroperability is enabled. This can be for reasons such asefficiency, security, end-to-end communication requirements etc.In terms of error handling each protocol has its own methods,but there is a gap for bridging the errors across protocols.Centralized software bus and integrated protocol agents are usedfor integrating different communications protocols.However, the aforementioned approaches do not fit well in allIndustrial IoT application scenarios. This paper thereforeinvestigates error handling challenges for a multi-protocol SOAbasedtranslator. A proof of concept implementation is presentedbased on MQTT and CoAP. Experimental results show thatmulti-protocol error handling is possible and furthermore anumber of areas that need more investigation have beenidentified.

    A Feasibility Study of SOA-enabled Networked Rock Bolts2014In: Proceedings of 2014 IEEE 19th International Conference on Emerging Technologies & Factory Automation (ETFA 2014): Barcelona, Spain, 16-19 Sept. 2014, Piscataway, NJ: IEEE Communications Society, 2014, p. 1-8, article id 7005072Conference paper (Refereed)
    Abstract [en]

    The use of rock bolts in the mining industry is a widely used approach for increasing mine stability. However, when compared to the automation industry, where the use of sensors and real-time monitoring of processes have evolved rapidly, the use rock bolts have not changed a lot during the last 100 years. What is missing are technologies for keeping installed rock bolts under real-time and online monitoring. One problem is that rock bolts can become damaged by seismic activities or movements within the rock, and thus lose their load bearing capacity. If that happens, the outer shell of a tunnel’s walls or ceiling can collapse, with disaster as a result. Therefore, there is a clear need for online and real-time monitoring solutions for strain and thereby stress, as well as seismic activity. In this paper, the current state of art in research around intelligent rock bolts is presented. An intelligent rock bolt is the combination of a traditional rock bolt with an Internet of Things device, i.e. a rock bolt with embedded sensors, actuators, processing capabilities and wireless communication. In the proposed architecture, every rock bolt has its own IPv6 address and can establish a wireless mesh network in an ad-hoc manner. Bymeasuring strain and seismic activity and exposing the sensors in the form of services, large gains in terms of safety and efficiently can be achieved. A number of mining related activities such as stress on the rock bolt can be detected, falling rocks and the presence of mobile machinery can be observed. Since the network is based on standard communication protocols such as IPv6, it is vital to add security mechanisms to prevent eavesdropping and tampering of data traffic. By utilizing the real-time monitoring capabilities of a network of Internet-connected intelligent rock bolt, it is possible to drastically improve monitoring of mining activities and thereby providing workers with a safer working environment.

    Application system design: maintenance2017In: IoT Automation: Arrowhead Framework / [ed] Jerker Delsing, Boca Raton, FL: CRC Press , 2017, , p. 366p. 248-280Chapter in book (Refereed)
    Abstract [en]

    In this section the use and role of the Arrowhead Framework in large multifunctional industrial automation environments is discussed. The basic scenario is related to enabling industrial IoT and connectivity of devices in a process industry setting. The basic motivation for the Arrowhead Framework - to facilitate the interoperability of IoT devices - is discussed in the light of practical pilot examples. The pilots are from the mining industry focusing on various examples related to maintenance. These examples were chosen due to the frequent wear in mining production equipment and the difficulties associated with traditional condition monitoring for production equipment scattered over long distances. Consequently, the new IoT solutions for gathering and analysing data in the mining industry have high potential for lowering maintenance costs and increasing the availability of production equipment.

    EXIP: A Framework for Embedded Web Development2014In: ACM Transactions on the Web (TWEB), ISSN 1559-1131, E-ISSN 1559-114X, Vol. 8, no 4, article id 23Article in journal (Refereed)
    Abstract [en]

    Developing and deploying Web applications on networked embedded devicesis often seen as a way to reduce the development cost and time to marketfor new target platforms. However, the sizeof the messages and the processing requirements of today's Web protocols, such as HTTP and XML,are challenging for the most resource-constrained class of devicesthat could also benefit from Web connectivity.New Web protocols using binary representations have been proposedfor addressing this issue. Constrained Application Protocol (CoAP)reduces the bandwidth and processing requirementscompared to HTTP while preserving the core concepts of the Web architecture.Similarly, Efficient XML Interchange (EXI) format has been standardizedfor reducing the size and processing time for XML structured information.Nevertheless, the adoption of these technologies is lagging behind due to lack ofsupport from web browsers and current Web development toolkits.Motivated by these problems, this article presents the design and implementationtechniques for the EXIP framework for embedded Web development. The frameworkconsists of a highly efficient EXI processor, a tool for EXI data binding basedon templates, and a CoAP/EXI/XHTML Web page engine.A prototype implementation of the EXI processor is hereinpresented and evaluated. It can be applied to Web browsersor thin server platforms using XHTML and Web servicesfor supporting human-machine interactions with constrained hosts.This article contains four major results: (1) theoretical and practical evaluation of the use of binary protocolsfor embedded Web programming; (2) a novelmethod for generation of EXI grammars based on XML Schema definitions;(3) an algorithm for grammar concatenationthat produces normalized EXI grammars directly, and hence reducesthe number of iterations during grammar generation;(4) an algorithm for efficient representation of possible deviations from theXML schema.

    An Efficient Access Control Method for Resource Constrained Embedded Systems2014Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The way to communicate and distribute the information in Wireless Sensor Networks (WSN) is constantly under evolution; at beginning the networks sent the information using proprietary protocols; but today, using IP protocol has become widely used to improve the interoperability and to standardize. These nodes often are constrained re- source devices and are not able to use the same mechanisms that a normal computer uses, because the processing performance and memory capacity are smaller than a nor- mal computer.With standardized protocols, like CoAP, an embedded device is able to create and offer resources to others. In some applications the data is confidential and must be pro- tected against intruders, for this reason the use of encryption techniques is mandatory; but even with encryption there is no mechanism to control the access to each resource and with method is used to access. Also standard computing solutions are not directly applicable, because the power consumption and processing performance. Therefore all resources are accessible to anyone with permissions to connect to the embedded device.In this thesis a new method of access control for resource-constrained devices is pro- posed as a extension of CoAP protocol. Which keep the original concepts of low-power and small processing overhead.This method can be a small step forward on the WSNs evolution. The results obtained are only about the method, the integration of this method into a complete access control framework is part of future work.

    An Authentication and Access Control Framework for CoAP-based Internet of Things2015In: IECON 2014: 40th Annual Conference of the IEEE Industrial Electronics Society, Dallas, TX, USA , Oct. 29 2014 - Nov. 1 2014, Piscataway, NJ: IEEE Communications Society, 2015, p. 5293-5299Conference paper (Refereed)
    Abstract [en]

    Internet of Things (IoT) and Cyber-physical Systems (CPS) are two very hot research topics today, and more and more products are starting to appear on the market. Research has shown that the use of Service Oriented Architecture (SOA) can enable distributed application and devices to device com- munication, even on very resource constrained devices, and thus play an important role for IoT and CPS.In order to realize the vision of Internet of Things, communica- tion between devices must be secured. Security mechanisms for resource constrained devices has attracted much interest from the academic community, where research groups have shown solutions like IPsec, VPN-tunnels, (D)TLS, etc. are feasible to use on this type of networks. However, even though the use of well- known security mechanisms are vital for SOA-based IoT/CPS networks and systems to be protected, they do not provide any fine-grain access control.In this paper, a CoAP-based framework for service-level access control on low-power devices is presented. The framework allows fine grain access control on a per service and method basis. For example, by using this approach a device can allow read/write access to its services to one group of users while only allowing read access to another group. Users without the right credentials are not even allowed to discover available services. To demonstrate the validity of the proposed approach, several implementations are presented together with test results.The aim is to provide a holistic framework for secure SOA- based low power networks comprise by resource constrain devices.

    Enabling cloud-connectivity for mobile internet of things applications2013In: Proceedings: 2013 IEEE 7th International Symposium on Service-Oriented System Engineering, SOSE 2013, Piscataway, NJ: IEEE Communications Society, 2013, p. 518-526Conference paper (Refereed)
    Abstract [en]

    The number of small embedded devices connected to the Internet is increasing. This growth is mostly due to the large number of Internet of Things (IoT) deployments, withapplications such as: industrial monitoring, home automation, and others. One common aspect with the majority of application areas is the lack of mobility. Most IoT devices arestationary and often use IEEE 802.15.4/6LoWPAN solutions. When a high level of mobility is required, the use of IEEE 802.15.4 is not possible without adding additional hardware for the user to carry.In this article, a holistic network architecture consisting of heterogeneous devices is presented. The architecture is composed of Embedded Internet Systems (EIS) and uses standard communication protocols. One important feature is the use of the Service-oriented architecture (SOA) paradigm. The use of SOA, by utilization of the CoAP protocol and standard services, enables the proposed architecture to exchange sensor-and actuator data with an Internet-based cloud as well as a user’s local cloud consisting of sensor IoT devices, smart phones and laptops. Another component of the architecture is a web-based human-machine interface for configuration, monitoring and visualization of sensor and actuator data using emerging web technologies for structured data processing.Results from experiments and real-world tests show that the proposed architecture can support sample rates of up to several kHz while enabling sensor data to be transmitted to SOA services in real time. This proves that the use of SOA, and RESTful web services in particular, is feasible on resource-constrained platforms while supporting true mobility.

    Efficient IoT Framework for Industrial Applications2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The use of low-power wireless sensors and actuators with networking support in in-dustry has increased over the past decade. New generations of microcontrollers, new hardware for communication, and the use of standardized protocols such as the Internet Protocol have resulted in more possibilities for interoperability than ever before. This in-creasing interoperability allows sensors and actuator nodes to exchange information with large numbers of peers, which is beneficial for creating advanced, flexible and reusable systems.The increase in interoperability has resulted in an increase in the number of possible attacks from malicious devices or users. For this reason, the use of encryption techniques to protect client and server communications has become mandatory. However, even with state-of-the-art encryption mechanisms, there is no protection that can control access to each particular service with fine-grained precision. The nodes within an industrial network of wireless sensors and actuators are resource-constrained embedded devices, and increasing interoperability therefore requires a higher level of computation capabil-ities. The nodes’ intrinsic limitations of memory and processing exert an adverse effect on power consumption and communication delays, resulting in a shorter battery life-time. Therefore, the standard computing solutions for Internet communications are not directly applicable, and new mechanisms to achieve security, scalability, dependability, interoperability and energy efficiency are needed.Sensor and actuator networks can transmit sensed data, but they also offer access to the actuators. Such accesses, presumably provided via services, require an access protection scheme. For this reason, the use of access control mechanisms is mandatory. Access control assists in the creation of customized services and access policies. These access policies can isolate access permissions to devices with different roles, such as production and maintenance.The main contribution of this thesis is a novel, efficient IoT framework for industrial applications, including design, implementation, and experimental validation. The frame-work includes features for communication protection, authentication, fine-grained access control, zero-configuration networking, and run-time reconfiguration. These technologies and their corresponding energy consumption data clearly demonstrate the feasibility of integrating a battery-operated IoT concept into a functional System of Systems. The provided data also pinpoint the most critical areas for improvement.
