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

针对大规模通信网络中多个用户共享的每个数字内容项频繁更新的情况，提出了一种使共享内容项保持一致的基本方法。通过这种方法，网络用户不仅能够以最小的代价在网络中的其他用户之间分享自己喜欢的内容项，而且还摆脱了不得不根据源节点检索不同版本的内容项的不便情况。通过计算机仿真对该方法的有效性进行了评估。

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.
