Application Layer Protocols for IoT Health Care Applications: COAP and MQTT review

The IEFT has suggested the CoAP protocol, which provides a flexible architecture and manner of communicating amongst IoT parties, eliminating the issue of standardization and open architecture that has hampered academics seeking to oversee the IoT's proliferation. They are unable to handle the issue of enormous volumes of data exchanged on the channels while monitoring the system. The only option to reduce this amount is by lowering recorded sensor values, which is dangerous in most applications that require a reaction in critical instances, most notably healthcare. Despite these strategies, CoAP remains unsolved. MQTT is a light communications protocol that cannot accommodate huge payloads, yet it is suitable for IoT applications. MQTT transmits sensor data reliably. MQTT does not transport photos, movies, or audio. Unencrypted MQTT data can be eavesdropped. MQTT's TCP requires clients to stay up throughout a session, restricting their capacity to preserve power by not napping. Given MQTT's importance and pervasiveness in current applications, we are evaluating how to make some modest tweaks to the protocol so it may be utilized across all IoT services
