Data Exchange Interoperability in IoT Ecosystem for Smart Parking and EV Charging

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.

Data discovery method for Extract- Transform-Load

“…However, one of the limitations of these use-case scenarios is their inability to demonstrate the semantic interoperability between different involved entities. Nevertheless, the capability of O-DF to enable semantic interoperability by semantic enrichment of object has been well documented in (Karpenko et al 2018) within the context of mobility domain.…”

A Review of Internet of Things Technologies for Ambient Assisted Living Environments

“…There are a lot of initiatives and vendors, producing and fostering their own IoT solutions and devices/things using use different interoperability standards. However, these standards are not aligned and usually are not interoperable with each other [106,107]. This leads to the very fragmented IoT market, where users are forced to choose and use specific equipment from one producer with very limited ability directly combine different IoT platforms into one solution.…”

Optimal Dispatching of Electric Vehicles Based on Smart Contract and Internet of Things

“…Distributed energy shares the power supply of the power grid and reduces environmental pollution, but because of its dependence on the environment, it increases the instability of power system [1]. As the use of EVs increases, the large-scale charging of EVs will also have a significant impact on the stable operation and planning of the power system [2], [3]. This impact is particularly evident when a large amount of users select fast charging modes.…”
