Adapted Cloudlet for Mobile Distance Learning: Design, Prototype and Evaluation

The Open and Distance Learning (ODL) currently operated by some institutions in Nigeria has problems of accessibility from remote locations due to bandwidth and latency issues. To address accessibility problem caused by network delays, cloudlet computing is introduced. With cloudlet technology, distant mobile learners are able to connect to the nearby cloudlet and access the learning content. Instead of relying on a distant cloud with latency issues during access, a nearby cloudlet with rich resources could go a long way to address the resource poverty of a mobile device. This paper presents an architectural design and a prototype implementation of an adapted cloudlet for mobile distance learning. The paper proposes a feature in which the learning content in the cloud or cloudlet platform is adapted to a nearby mobile learner depending on the availability of platform with minimum delays in terms of bandwidth and latency.
