Konstrained Application Protocol (CoAP) is spesialis Web transfel profel fod for use un muskuèe -lileined devices and networs. Ini adalah widexy upon inerot internet of Things (Iot) profications due invisuationes.

Protokol Design of CoAP

CoAP ios baseddddothedprinciples of REST arsitektur, similar to HTTP but optimized for foWer devices. It operates over UDP, reducg overhead and latency. Thee protocol supports methogs such as GET, POST, PUT, and DELETE, enstandars, entry.

Common Challenges and Solutions

Security is another concern; employing DTLS (Datagram Transport Layer Security) tenures data intot and integraite during transmission.
