Abstract

During the last decades the Internet has become ubiquitously available in most places of the world, which has made it possible also to implement the Internet of Things (IoT) paradigm. In this paradigm Internet connects devices with each other and with their users allowing the development of digital services and applications that increase the comfort level of everyday human life. Many domains are interested to exploit the IoT ecosystem, especially public administrations starting \textit{Smart City} initiatives all over the world. Cities are becoming smart in many way: smart mobility, smart buildings, smart environment and so on. However, the problem of noninteroperability in IoT exists that hinders the seamless communication between all kinds of IoT devices. Different domain specific IoT applications use different messaging standards offered by different providers. These messaging standards do not comply with each other. The Open Group published two domain-independent standards O-MI and O-DF aiming to solve this interoperability problem. In this thesis we want to describe the practical use of O-MI/O-DF standards in a mobile application for the smart city context, in particular for the Smart Mobility domain, electric vehicle (EV) charging use case. First, the overview of IoT domain and its ecosystem with attention to noninteroperability problem is made. Then the description of six messaging standards including Open Group's standards O-MI and O-DF are provided. Then the requirements for IoT messaging protocol are outlined and the comparison of all these messaging standards are made showing that the domain independent standards O-MI/O-DF are the most suitable for IoT. After that smart city context and its requirements are described for the implementation part of the thesis. In the next chapter the implementation of a mobile application using O-MI/O-DF messaging standards are described with the details of the application architecture, structure of messages and overview of the back-end part of the service.
