Peer-review of Reusable Learning Objects for Ebooks in a Peer-to-peer Network Architecture
It is a challenging task to take standards-based eLearning content from a client-server environment and place it on a Peer-To-Peer network to achieve similar goals. The client-server eLearning system architecture is designed for storing, sharing and delivering course content. In an initial pursuit of this challenge, a design for a Peer-ToPeer Reusable Learning Object Repository was proposed and...
متن کاملTAC: A Topology-Aware Chord-based Peer-to-Peer Network
Among structured Peer-to-Peer systems, Chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. However, Chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing late...
متن کاملReusable Learning Objects Through Peer Review: The Expertiza Approach
Homework is frequently viewed as a necessary evil—one of the least exciting parts of teaching, but absolutely essential if students are to learn the material. There are many reasons for this attitude. Reusing the same assignments year after year invites cheating (Gehringer 2004) and devising challenging new work is time consuming. Grading is drudgery for faculty or teaching assistants, especial...

متن کاملA Novel Caching Strategy in Video-on-Demand (VoD) Peer-to-Peer (P2P) Networks Based on Complex Network Theory
The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...
