Abstract
In recent years, peer-to-peer technology has been widely applied to many areas, including file sharing, networked TV, and instant messaging. This thesis tried to build a storage system over this popular network architecture.
This thesis proposed a file distribution strategy based on the nodes’ lifetimes. Some researches show that the longer a node stay online the more likely it still online in next hour. We take this observation as the basis of file distribution: putting the files over the nodes with longer life. We expect this strategy would bring a better file availability. This system is built over a pure P2P architecture, and we use Distributed Hash Table (DHT), a structured overlay network, to locate the data object efficiently. The experiment results show that the lifetime based distribution strategy performs well in file availability.
