Optimum contents deployment in Peer-to-peer networks taking account of update consistency

点击翻译按钮获取中文摘要

Based on the situation that each digital content item shared by a lot of users in a large-scale communication network is frequently updated, we proposed a basic method to make the shared content items consistent. By this method, network users not only come to be able to share their favorite content items among the other users in the network at the least cost, but also get rid of the inconvenient situation that they have no choice but to retrieve content items of different versions depending on the source peers. The efficiency of the proposed method is evaluated by using computer simulations.
