Abstract
In this paper, we aim to apply the Internet of Things (IoT) technology to the E-learning environment and create a global learning system that utilizes available learning resources all over the world. We have called it the free learning (F-learning) system. We introduce a simple F-learning architecture consisting of smart classrooms and remote and virtual labs. These components communicate with each other autonomously using the IoT concept. We apply the Constraint Application Protocol to the proposed F-learning system. Network simulator NS2 is used to compare the efficiency of the F-learning environment to a traditional E-learning one. The simulation results show that the F-learning system has lower packet loss and delay as well as larger throughput. We also show the feasibility of establishing the F-learning based on high-altitude platforms.
