QUIC, a general-purpose transport protocol, has recently been given consideration as a candidate solution for the Internet of Things (IoT). Researchers have proposed variants of application-layer protocols such as MQTT, CoAP, and AMQP all using QUIC transport. In this paper, we aim to show that since QUIC is so feature-rich on its own, many of the upper-layer complexities of traditional protocols can be greatly reduced or even eliminated. To exemplify this, we have designed what we call a 'QUIC thin-app' for IoT relying almost entirely on QUIC's specification. We achieved comparable functionality to MQTT, doing away with the need for much of its control messaging. Furthermore, our experimentation with our solution against MQTTv5 shows significant reductions in signaling overhead while maintaining comparable CPU and memory utilization.
