Chapter 4: Communication Protocols : Defining the Format and Structure of Messages in IoT Devices
Abstract: In the context of the Internet of Things (IoT), a "communication protocol" refers to a set of rules that govern how connected devices exchange data with each other, defining the format and structure of messages to ensure seamless communication across different types of IoT devices, considering factors like range, power consumption, and data rate needed for the application; examples include Zigbee, Bluetooth, LoRaWAN, and MQTT. Key points about IoT communication protocols: Function: They establish a standard way for devices to send and receive information, allowing diverse devices to interact with each other effectively. Considerations when choosing a protocol: Range: How far the devices need to communicate Power consumption: Battery life of devices Data rate: Amount of data needed to be transmitted Network topology: Whether a point-to-point, mesh, or star network is required Security requirements: Level of data protection needed ...
