Explore internet of things internetworking concepts and protocols, learn to implement machine-to-machine communication over IP on Arduino, and apply application layer protocols through hands-on projects with cloud data exchange.
This lecture summarizes the hardware and software requirements to successfully complete the course.
Install packet sender to send and receive tcp and udp packets between your computer and an arduino; set a fixed udp port, like 50000, and save reusable packets.
Install the Copper (Cu) browser extension for Firefox to communicate with Arduino devices using the CoAP protocol via a graphical interface, enabling resource discovery and post/put messaging.
The lecture outlines the IoT components, including things, sensors, actuators, controllers, and gateways. It explains how gateways bridge controllers to the IP network to enable data exchange, storage, and applications.
Explore the internet protocol suite, detailing layered structure across link, transport, and application layers, roles of IP, TCP, and UDP, and how IETF standards, RFCs, and DNS enable data delivery.
Explore the components of a network, including MAC addresses, switches, routers, gateways, and firewalls, and see how local area networks connect to the internet via the IP protocol stack.
Explore transport layer protocols that enable end-to-end communications for multiple applications on a single network connection, using 16-bit port numbers to distinguish well-known, registered, and dynamic ports.
Configure the Arduino to receive and process UDP packets over port 50000, manually set the MAC address, and print source IP, port, and payload to serial for verification.
Connect the Arduino to the network to obtain ip address, subnet mask, default gateway, and optional name server ip from the dhcp server; print these details to the serial console.
Demonstrate how an Arduino renews a DHCP lease to maintain its IP binding. Learn how lease times, binding, and renewal every 20 seconds prevent IP conflicts on the network.
IP communication is the essence of the Internet of Things. Software developers, architects and IoT professionals face networking challenges during system design and implementation. To achieve success, it is fundamental to understand how IoT devices interact with each other and how they communicate through the Internet and with the cloud.
Learn and Implement Networking Protocols for the Internet of Things in this Comprehensive Course.
Understand networking protocols used in IoT (IP, TCP, UDP)
Learn IoT protocols (CoAP, MQTT)
Understand and implement network services (DHCP, NTP, DNS, HTTP)
Implement End-toEnd IP networking with Arduino
Connect your IoT devices to each other, to the Internet and to cloud services
Mastering networking protocols for the Internet of Things
Broken down, the Internet has some decades of history and its operation is defined by internetworking protocols. The IoT phenomenon brought the need for new communication protocols, specially fit for devices with constraint resources.
In this course you may learn how all these protocol work and how they are built on each other. You will also learn how to design and implement an end-to-end networking solution for your IoT project.
Contents and Overview
I designed this course to cover both theory and practice. In the lectures I explain how and why we use each protocols and show how to implement them on Arduino controllers. We will discuss pros and cons of different implementations, dependencies between protocols and best practices of their choice.
