IoT Communication: Protocols for Device and Cloud Connectivity

Ever wondered how smart devices exchange data with each other and the cloud in real time? Understanding the underlying networks and protocols is the key to building responsive, reliable Internet of Things (IoT) systems. In this course, you will transition from a curious beginner to a confident practitioner capable of designing robust IoT communications. You will study how data travels across networks, evaluate the trade-offs between latency and reliability, and implement industry-standard communication protocols for voice, text, and sensor data. What you'll learn: - Understand the foundations of network architectures and how devices route data to the cloud - Configure Session Initiation Protocol (SIP) to establish real-time voice and text communications - Apply lightweight messaging protocols like MQTT and CoAP designed for resource-constrained IoT hardware - Analyze the trade-offs between high-reliability signaling and latency-sensitive real-time streaming - Implement modern security practices, including transport-layer security (TLS) for encrypted device communication The course starts with fundamental networking concepts and key terminology before guiding you through hands-on written exercises. You will explore practical code examples to build signaling structures and connect devices seamlessly. This course is designed for beginners interested in smart technology, hardware programming, or network engineering, with no prior IoT communication experience required.
