CoAP (Constrained Application Protocol)

The Constrained Application Protocol (CoAP) is a specialized communication protocol designed for devices with limited resources, such as those in the Internet of Things (IoT). It enables these devices to send and receive messages efficiently over the internet. CoAP is lightweight, meaning it requires less power and bandwidth, making it ideal for sensors and actuators in smart homes or industrial applications. It operates similarly to the web's HTTP but is optimized for small, constrained environments. This allows devices to work together seamlessly, exchanging data and commands, ultimately enhancing automation and connectivity in various settings.
