Abstract
Many domains are trying to integrate with the Internet of Things (IoT) ecosystem, such as public administrations starting smart city initiatives all over the world. Cities are becoming smart in many ways: smart mobility, smart buildings, smart environment and so on. However, the problem of non-interoperability in the IoT hinders the seamless communication between all kinds of IoT devices. Different domain specific IoT applications use different interoperability standards. These standards are usually not interoperable with each other. IoT applications and ecosystems therefore tend to use a vertical communication model that does not allow data sharing horizontally across different IoT ecosystems. In 2014, The Open Group published two domain-independent IoT messaging standards, O-MI and O-DF, aiming to solve the interoperability problem. In this article we describe the practical use of O-MI/O-DF standards for reaching interoperability in a mobile application for the smart city context, in particular for the Smart Mobility domain, electric vehicle (EV) charging case study. The proof-of-concept of the smart EV charging ecosystem with mobile application user interface was developed as a part of an EU (Horizon 2020) Project bIoTope.
Highlights
Over the last 20 years, the Internet has become widely used in the world [1]
These applications can allow citizens, companies, and public administrations to benefit in everyday life by using new digital services that are built on top of an Internet of Things (IoT) ecosystem [3]
The electric vehicle (EV) charging example demonstrates that it is possible to create distributed, bottom-up services, based on open standards, that can contribute to the smart cities ecosystem
Summary
Over the last 20 years, the Internet has become widely used in the world [1]. Ubiquitous connectivity, provided by Internet, has enabled the communication paradigm called the Internet of Things (IoT). 2002, in the article by Huvio, Grönvall, and Främling [2], who created a lightweight distributed system to share information by using peer-to-peer connections for tracking shipments, and for accessing any product information during a product’s lifecycle, including sensor readings and other events Following this definition, IoT allows the development of a huge variety of applications in various industries that will use the enormous quantity of data generated by IoT devices such as cameras, home appliances, sensors, actuators, vehicles, and so on. The evaluation, relying on an innovative EV charging use ecosystem that breaks the barriers of vertical silos and enables horizontal interoperability; and case, was achieved in terms of throughput anddata response times. This enables conclusions to be drawn (iii) evaluated this proposition through a real implementation of the bIoTope ecosystem, within the on future work. System interoperability a growing area of interest in the industrial domain, due to the
