A Method for Localization of Computational Node and Proxy Server in Educational Data Synchronization

Localization methods enable location estimation accurately and provide location information about mobile devices, people, cars, data and equipment. Accurate location detection is a vital process for most of location-based applications such as emergency rescue, in-building guidance, security services, and product tracking in hospitals. This paper addresses localization of student/teacher tablets and school level proxy servers for educational data synchronization. For this purpose, locations of proxy servers and tablets are detected using Android Location API. After localization, if tablets are outside of school, they could access cloud server directly to get educational data and if tablets are in school, they could access data via proxy server. Experimental results show that the proposed technique increases the efficiency in data transfers between the end users and cloud servers.
