Therefore, we proposed a distributed MQTT broker optimized architecture. However, the paper did not handle the authentication mechanism between brokers. 0, 1, 2: retain: N: Defines whether the message is saved by the broker as the last known good value for a specified topic. The protocol uses in-band signalling (i.e., reuses MQTT primitives for the control messages) and allows for full message replication among brokers, as well as robustness against failures. Message Queue Telemetry Transport (MQTT) is one of promising protocol for data exchange in IoT that could encounter such issues because it relies on central broker located in Cloud, and this may lead to increase network congestion, performance overhead or bottleneck.
