Outline of Final Research Achievements |
In this research, we proposed a basic method for an efficient contents sharing in Hybrid Peer-to-Peer network. Although we already succeeded to reduce contents retrieval cost largely by deploying appropriate number of replicas for each content item at appropriate locations in conventional methods, we improve the methods by splitting content files and using differences between similar content items in order to work the system more efficiently. The effectiveness of the proposal was evaluated by computer simulations.
