In this paper, variety of ways for the teachers to have easy access to various multimedia contents for teaching by setting up multimedia devices that could replay educational contents as a network in the classroom were researched. In order to achieve this kind of short distance communication, ZigBee based sensor network was setup to simulate the classroom network and underwent a test procedure. The simulator designed and implemented in this study is based on ZigBee that could establish classroom networks at a low cost and by providing a simulation environment through smart phone controlled multimedia devices, it is expected that the study may help to effectively establish an efficient classroom network environment that can utilize various types of educational multimedia contents with ease during classes.
