Optimization of Assisted Search Over Server-Mediated Peer-to-peer Networks

Accompanied by improving accessibility of data and storage and the invention of the blockchain economy, advantages of the peer-to-peer network in privacy and efficiency over server-client systems have become more significant recently. One of the most popular applications of peer-to-peer networks is file transferring, where each peer stores a partial segment of a file and the requester can aggregate each piece into a single file when downloading it. To optimize the performance of file transmission, one goal is to increase the searching speed for the file location over the network. In this paper, we analyze the server-mediated peer-to-peer networks, which is an uncommon architecture mentioned in previous works but can potentially improve the search speed, and minimize the average number of hops during flooding search.
