MOKSHA ― Waves of Knowledge

摘要

In this paper, we propose an application called MOKSHA for efficiently delivering information, in particular, course contents to mobile users. MOKSHA has been designed keeping in mind the following issues: 1) the client device that is a low-end system in terms of battery power, memory capacity, computational power and display features, and 2) wireless channel characteristics such as low bandwidth and frequent disconnections. MOKSHA assumes that a mobile device has three time varying connectivity modes: network connectivity, peer-to-peer connectivity and stand-alone mode. In order to work effectively in such conditions, MOKSHA implements strategies used for caching the course contents on the mobile device of the end user. Such strategies account for the user behavior, the end device characteristics and connectivity mode and the course contents.
