Investigation of message queuing telemetry transport in term of bandwidth efficient in internet of thing / Ahmad Musyawir Abdul Ghani

Message Queuing Telemetry Transport (MQTT) is a transmission protocol used in IoT technology. MQTT become more havoc day by day since people are accepting the use of IoT devices for numerous internal or external purpose of business and lifestyle. The closeness war between other existing IoT protocol such as HTTP and CoAP has caused a possibility and questioned which whom is better amongst them. Unlike HTTP, it often used on website while CoAP more likely wide known in IoT devices id the real deal where between CoAP and MQTT who is better. The problem is MQTT a reliable and bandwidth efficient protocol as people already knows. The full performance analysis is one by considering into account the specific testing and scenarios between three devices which involving broker, arduino and raspberry pi. Therefore, transmission of temperature and humidity between clients cross over the broker is carried out and analysis by monitoring Wireshark in order to clarify the MQTT bandwidth efficient problem. This research is conducted by suing python environment and the network topology used in this research is bus topology. This research studied the traffic received and sent by protocol and bandwidth management. The findings summarized that MQTT is right helps data sent to other devices in least bandwidth consumption even though there is interference at end-to-end delay in sending the data packet.
