Evaluation of MQTT Protocol for E-Learning

In this paper, we aim to apply the Internet of Things (IoT) technology to the E-learning system and create e- learning system that uses available learning resources all over the world. There many application protocols in IoT, this paper will focus on the use of Message Queue Telemetry Transport (MQTT) to the proposed e-learning system. MQTT will be evaluated for the e-learning application. The evaluation will be carried out using network simulation for different e-learning scenarios. The study is carried out by means of simulation using OMNET++ and we develop simulation model by using INET framework. The study found that the average end to end delay (mean) will be increased, when packets received and sent increase and the congestion will be increased in broker when the number of MQTT clients (publishers and subscribers) are increased resulting in stopped working broker before completing the time limit for these scenarios
