| Abstract | Limitations on traditional client-server based e-Learning architecture have been studied. There is the overhead in a single learning server and inefficient use of resources. There is a lack of real-time interactiveness among learning group members therefore learning is not effective. There is also difficulty in the collaborative work and e-Learning systems are often too disconnected from the learner's current preferences and goals. For instance, E-learning systems often propose a learning agenda that does not reflect the current user's needs, interests, etc. "Therefore learners may feel lonely, may not be actively participate in the learning activities and may leave the system as well. Novel mechanisms for next generation e-Learning architecture are proposed using peer-to-peer technologies. Such mechanisms include the formation of the interest based groups for synchronous, collaborative and interactive e-Learning system where every learner can contribute their resources to group by efficient communication mechanisms. Adaptation and management of such interest based groups such as merging, splitting, maintenance etc are also incorporated and all mechanisms are tested and implemented on the top of application layer using the Internet environment. Purposed MVRing based application layer group communication scheme is evaluated and compared with existing tree based approaches of doing application layer multicasting in structured peer-to-peer networks such as CAN, Pastry, Chord and Tapestry. Mathematical analysis of MVRing based protocol is presented and evaluation is done using Internet experiments and NS-2 simulations. MVRing based protocol provides uniform distribution of node degree, significantly high fault tolerance level, comparable link stress, multicast traffic and latency with respect to the tree based ALM scheme. Several new features incorporated in MVRing based protocol, that are not present in existing tree based ALM scheme, are also evaluated and studied such as heterogeneity among nodes, interest based group merging/splitting, group maintenance mechanisms etc. Therefore, MVRing based interactive common interest group adaptation mechanisms with structured p2p technologies for e-Learning will combine the tools that are already available, independent of the installed infrastructure and offer a great deal of potential for workgroup collaboration, communities of practice, and selfdirected e-Learning. |
