Abstract
Starting from the RFID and the wireless sensor networks, the Internet of connected things has attracted the attention of major IT companies and later, of the industrial environment that recognized the concept as one of their key axes for future growth and development. The implementation of IoT in the industrial environment raises some significant issues related to the diversity of fieldbuses, the large number of devices and their configuration. The requirements related to reliability, security and real-time are very important. This paper proposes an industrial IoT and communications at the edge framework which has some outstanding features related to: the easy integration of fieldbuses and devices used in industrial environments with automatic configuration features, integration of multiple middleware technologies (CORBA, OPC and DDS), the uncoupling of the industrial activity from the publishing data on the Internet, security at different levels of the framework. Another important feature of the proposed framework is that it is based on mature standards and on open source or public implementations of these standards. The framework is modular, allowing the easy integration of new fieldbus protocols, middleware technologies and new objects in the client application. This paper is focused mainly on CORBA and DDS approaches.
Highlights
KEVIN Ashton, from the MIT Auto-ID Center, was the first who proposed the term "Internet of Things" (IoT), referring to the connection between the information provided by radio frequency identifiers (RFID) and the Internet [1]
This situation is generated by the need to ensure a high level of determinism, safety, and security during the production process and to avoid both critical security failures and costly production interruptions. These objectives should be IIOT-specific, including a high level of automation for the network configuration processes. It is proposed an Industrial IoT (IIoT) framework organized on three levels, based on the three observations outlined above: the device that integrates the hardware in order to sense/control the physical world and to acquire data, middleware for data transport and an www.ijacsa.thesai.org (IJACSA) International Journal of Advanced Computer Science and Applications, Vol 7, No 9, 2016 application which provides the means to interact with the user and other IoT applications [14]
Due to the success it recorded in the fields of information and communication technologies (ICT) and embedded systems, either connected to each other or to the Internet, wired or wireless, it will lead to a convergence between the physical and the virtual world
Summary
KEVIN Ashton, from the MIT Auto-ID Center, was the first who proposed the term "Internet of Things" (IoT), referring to the connection between the information provided by radio frequency identifiers (RFID) and the Internet [1]. These objectives should be IIOT-specific, including a high level of automation for the network configuration processes (including the fieldbuses pertaining to the industrial environment) In this paper, it is proposed an IIoT framework organized on three levels, based on the three observations outlined above (italic): the device that integrates the hardware (sensors, actuators, RFID) in order to sense/control the physical world and to acquire data, middleware for data transport and an www.ijacsa.thesai.org (IJACSA) International Journal of Advanced Computer Science and Applications, Vol 7, No 9, 2016 application which provides the means to interact with the user and other IoT applications [14].
