Contracting Service for Industrial Internet

Abstract

Internet of things (IoT) is an emerging vision of a world, where machines can communicate with each other and with people. Industrial Internet of Things (IIoT) is a subset of IoT applications used for industrial purposes. Since this vision is relatively new, current IIoT applications do not follow communication standards. Although, many standards have recently been proposed, however none of them are widely accepted. Moreover, all of the device management platforms are proprietary, thus restricting interoperability.

This thesis proposes a new web platform for management of devices in terms of access control. To choose the appropriate standard many standards were studied and presented, such as World Wide Web Consortium - Web of Things (W3C WOT) and Light-Weight Machine to Machine (LWM2M). Requirements for this platform were gathered by carefully examining the use cases of smart industrial machines.

The underlying principles for the platform is the division of tasks among user groups, e.g., manufacturer and customer. For instance, manufacturers responsibility is to add machines to the platform and assign them to customers; Customer is tasked with defining who has access to their machines by manipulating policies. This web platform was developed and evaluated in line with the requirements and based on LWM2M and Policy Based Communications research.
