- 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.

- 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.

- 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.

Efficient IoT Framework for Industrial Applications

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- 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.
