Augmenting objects, otherwise designed to perform a specific task, with the ability to connect to the Internet has led to a new technological paradigm called the Internet of Things (IoT). This course will introduce the students to this concept where high level tasks such as data analytics and fundamental hardware components, such as sensors and actuators are integrated to produce complex systems aimed at improving quality of life and benefit society. Considering the upcoming IoT revolution, this course unit offers a timely opportunity to familiarise yourself with the fundamental principles and primary issues that define the IoT. We put emphasis on the versatility of components that can be integrated into such systems, as well as the diversity of data types produced by the IoT edge-nodes. Successful development of IoT applications also requires communication between different levels (layers) of IoT architectures with the associated security and privacy issues.

Students who are not from the School of Computer Science must have permission from both Computer Science and their home School to enrol.


Demystify the IoT concept. Offer insight into the IoT components and explain the different principles and the several aspects of designing the IoT architectures. The course will be focused towards the edge of the IoT that is the “Things” (i.e., the edge devices). Several IoT areas of application will be analysed, such as smart grids, home automation, and industrial IoT to demonstrate the different requirements and constraints in designing practical IoT architectures for these segments. Furthermore, the course will analyse the importance of the security, trust, and privacy issues for IoT and present techniques that address these. The course will also demonstrate the interplay and the role of diverse engineering and computer science fields that compose the IoT ecosystem.

Learning outcomes

  •  Identify the basic organization and components that underpin IoT systems.
