Title: “Internet of Things: a Guided Systems Tour With Interoperability Focus”

Length: 2 hrs

Start Time: Aug 5, 2020, 13:00 (1 pm) PDT (US, Los Angeles)

Abstract

This tutorial presents an overview of the foundational principles, architecture, and design considerations in IoT systems. It includes coverage and analysis of key IoT system components including sensors, edge, fog, communications, cloud, data processing with analytics ML and AI, security and management. In addition to component analysis, major emphasis is on the system integration and how the various parts are put together and function as an ensemble to carry out the common objectives. The tutorial is designed to provide a balanced treatment at roughly equal level of depth for all covered topics, based on the presenter’s book “Internet of Things: Concepts and System Design” (Springer 2020). The presentation approach is function and purpose driven in the sense that each component is described in terms of the role it fulfills in the system’s overall mission. That is to safely and securely collect sensor data, analyze, and act on the findings in a manner that impacts the physical world.

An important focus of the tutorial is to highlight the importance of and the need for semantic interoperability in IoT systems. We describe how this requirement is different from the world-wide web and why it is necessary to enable big IoT data aggregations for meaningful insights and processing by ML and AI techniques. Interoperability also provides the ability to (re)use the collected data – arguably the most important asset of an IoT system - when changing an implementation or migrating to another platform. The structure of information and data models and metadata representations commonly used for the purpose are described and their salient features are identified. Several examples of IoT object definitions are provided from the evolving IoT standards to illustrate their similarities and differences. Different levels of pragmatic interoperability across domains and specifications are defined and ways for achieving them in practice are outlined.
