Cloud-edge MQTT messaging for latency mitigation and broker memory footprint reduction
Yi-Hsuan Tseng, Chao Wang, Yu-Tse Wei, Yu-Ting Chiang

TL;DR
This paper proposes a cloud-edge MQTT messaging system to reduce latency and save memory in IoT networks.
Contribution
The paper introduces new message scheduling policies and a memory allocation scheme for MQTT brokers.
Findings
The proposed design reduces latency in IoT data delivery.
The design saves about 75% of the MQTT broker's memory footprint.
The system is implemented using Eclipse Mosquitto and validated empirically.
Abstract
The deployment of smart-city applications has increased the number of Internet of Things (IoT) devices connected to a network cloud. Thanks to its flexibility in matching data publishers and subscribers, broker-based data communication could be a solution for such IoT data delivery, and MQTT is one of the widely used messaging protocols in this class. While MQTT by default does not differentiate message flows by size, it is observed that transient local network congestion may cause size-dependent latency additions, and that the accumulation of large message copies in the cloud broker could run out of the broker memory. In response, in the scope of cloud-edge messaging, this research article presents problem analysis, system design and implementation, and empirical and analytical performance evaluation. The article introduces three message scheduling policies for subscribers deployed at…
