Two way Communication Wireless Sensor Network between Teacher-Student Interaction System based on WI-FI and RFID

Based on analysis of features of WI-FI Wireless sensor networks and RFID technology, we implemented a protocol stack of WI-FI using method of module dividing. From the perspective of improving teaching methods, combining teaching practices, a teacher-student interaction system based on WI-FI and RFID technology was designed and implemented for the application of actual teaching. Results show that the system achieved the basic functions of a teacher-student interaction system.
