Abstract

Computer Base Test (CBT) or e-exam is often used to evaluate the achievement of learning process in e-learning system. E-exam services become more popular to be implemented by Massive Open Online Courses, TOEFL, IELTS etc. However, the security of e-exam is still debatable. Many researches related to e-exam security on the aspect of authority and confidentiality have been done. However, there are not many researches founded relate to availability aspect especially for implementation of e-exam in wireless environment. Here is introduced Time Adaptive for Mobile E-Exam (TAMEx) model. This model is designed for improving availability of e-exam which is implemented in wireless network especially in WLAN IEEE.802.11. This model deploys Netsh command to provide data of Wireless Local Area Network interfaces then integrate it with e-exam application. Here is used RSSI and received data rate to identify connection status of the client. In case of connection problem due to the RSSI or received data rate below the required standard, this model provides additional time automatically corresponding to duration of connection interruption to a certain user who has experienced of loss connection during the exam. Therefore, implementing TAMEx model in e-exam services should improve reliability of e-exam in wireless environment due to its availability, fairness and accountability.

介绍了无线环境下电子考试可用性的TAMEx模型

在电子学习系统中，通常采用计算机基础测试(CBT)或电子考试来评估学习过程的成果。随着大规模在线开放课程、托福、雅思等的实施，电子考试服务越来越受欢迎。然而，电子考试的安全性仍然存在争议。关于电子考试的安全性，人们从权威性和保密性两个方面进行了大量的研究。然而，在可用性方面，特别是在无线环境下实现电子考试的研究还不多。本文介绍了时间自适应移动电子考试(TAMEx)模型。该模型是为提高电子考试在无线网络特别是WLAN IEEE.802.11环境下的可用性而设计的。该模型采用Netsh命令提供无线局域网接口数据，并与电子考试应用程序集成。这里使用RSSI和接收数据速率来标识客户端的连接状态。当由于RSSI导致连接出现问题或接收到的数据速率低于要求的标准时，该模型会自动为某个在考试过程中失去连接的用户提供与连接中断持续时间相对应的额外时间。因此，在电子考试服务中实现TAMEx模型可以提高无线环境下电子考试的可靠性，因为它具有可用性、公平性和可问责性。
