Design And Planning Of E- Learning Environment/E-Education System On Heterogeneous Wireless Network Control System

摘要

Abstract: The purpose of this research is to provide a more efficient and effective communication method between teacher and student with the use of heterogeneous network. Moreover, the effective use of heterogeneous network can be emphasized. The system of e-education can develop utilizing wireless network.The e-Education system can help students to communicate with their teacher more easily and effectively using a heterogeneous wireless network system. In this wireless network system, students, who are blind or dumb, will also be able to communicate and learn from the teacher as normal students can do. All the devices or laptops will be connected on wireless LAN. Even when the teacher is not around, he will be able to help his students with their study or give instructions easily by using the mobile phone to send text or voice signal. When the teacher sends information to the dumb student, it will be converted into sign language for the student to be able to understand. When the dumb student sends the information to the teacher, it will be converted into text for the teacher to understand. For the blind student, text instructions from the teacher will be converted into audio signal using text-to-speech conversion.Thus, the performance of heterogeneous wireless network model can evaluate by using Robust Optimization Method. Therefore, the e-Education system's performance improves by evaluating Robust Optimization Method.
