Even lower latency in IIoT: evaluation of QUIC in industrial IoT scenarios

In this paper we analyze the performance of QUIC as a transport alternative for Internet of Things (IoT) services based on the Message Queuing Telemetry Protocol (MQTT). QUIC is a novel protocol promoted by Google, and was originally conceived to tackle the limitations of the traditional Transmission Control Protocol (TCP), specifically aiming at the reduction of the latency caused by connection establishment. QUIC use in IoT environments is not widespread, and it is therefore interesting to characterize its performance when in over such scenarios. We used an emulation-based platform, where we integrated QUIC and MQTT (using GO-based implementations) and compared their combined performance with the that exhibited by the traditional TCP/TLS approach. We used Linux containers as end devices, and the ns-3 simulator to emulate different network technologies, such as WiFi, cellular, and satellite, and varying conditions. The results evince that QUIC is indeed an appropriate protocol to guarantee robust, secure, and low latency communications over IoT scenarios.The authors are grateful for the funding of the Industrial Doctorates Program from the University of Cantabria (Call 2020).

And QUIC meets IoT: performance assessment of MQTT over QUIC

We study the performance of the Message Queuing Telemetry Transport Protocol (MQTT) over QUIC. QUIC has been recently proposed as a new transport protocol, and it is gaining relevance at a very fast pace, favored by the support of key players, such as Google. It overcomes some of the limitations of the more widespread alternative, TCP, especially regarding the overhead of connection establishment. However, its use for Internet of Things (IoT) scenarios is still under consideration. In this paper we integrate a GO-based implementation of the QUIC protocol with MQTT, and we compare the performance of this combination with that exhibited by the more traditional MQTT/TLS/TCP approach. We use Linux Containers and we emulate various wireless network technologies by means of the ns3 simulator. The results of an extensive measurement campaign, show that QUIC protocol can indeed yield good performances for typical IoT use cases.The authors are grateful for the funding of the Industrial Doctorates Program from the University of Cantabria (Call 2018).

Robust QUIC: integrating practical coding in a low latency transport protocol

We introduce rQUIC, an integration of the QUIC protocol and a coding module. rQUIC has been designed to feature different coding/decoding schemes and is implemented in go language. We conducted an extensive measurement campaign to provide a thorough characterization of the proposed solution. We compared the performance of rQUIC with that of the original QUIC protocol for different underlying network conditions as well as different traffic patterns. Our results show that rQUIC not only yields a relevant performance gain (shorter delays), especially when network conditions worsen, but also ensures a more predictable behavior. For bulk transfer (long flows), the delay reduction almost reached 70% when the frame error rate was 5%, while under similar conditions, the gain for short flows (web navigation) was approximately 55%. In the case of video streaming, the QoE gain (p1203 metric) was, approximately, 50%.This work was supported in part by the Basque Government through the Elkartek Program under the Hodei-x Project under Agreement KK-2021/00049; in part by the Spanish Government through the Ministerio de Economía y Competitividad, Fondo Europeo de Desarrollo Regional (FEDER) through the Future Internet Enabled Resilient smart CitiEs (FIERCE) under Grant RTI2018-093475-AI00; and in part by the Industrial Doctorates Program of the University of Cantabria under Grant Call 2019

Evolucion del Stack IoT: MQTT sobre QUIC

En este trabajo se analiza el rendimiento de QUIC como solución de transporte para dar soporte a servicios IoT industriales basados en Message Queuing Telemetry Transport (MQTT). QUIC fue desarrollado por Google para solucionar las limitaciones que presenta el protocolo de transporte dominante, Transmission Control Protocol (TCP). Para estudiar su comportamiento, se han emulado escenarios con características propias a estos entornos industriales, incluyendo QUIC como protocolo de transporte para MQTT y comparándose esta combinación frente a la solución tradicional basada en la pila TCP/TLS/MQTT. Para emular distintas tecnologías y condiciones de red se han empleado contenedores LXC de Linux a modo de dispositivos IoT mediante el simulador de eventos ns-3. Los resultados obtenidos ponen de manifiesto que QUIC podría ser una alternativa interesante como protocolo de transporte en escenarios IoT.Los autores agradecen la financiación del Programa de Doctorados Industriales de la Universidad de Cantabria (convocatoria 2020).
