Constrained Application Protocol

Constrained Application Protocol (CoAP) is a specialized internet protocol designed for simple devices in the Internet of Things (IoT), like smart sensors and home devices. It allows these devices to communicate efficiently over networks with limited resources, such as low bandwidth and low power. CoAP enables secure, lightweight messaging—similar to web protocols—so devices can send and receive data quickly and reliably. This makes it ideal for expanding connectivity in environments where power and bandwidth are limited, facilitating smarter homes, industrial automation, and other IoT applications.
