In order to enhance terrain data network service performance, P2P technology is gradually used in large scale terrain data roaming system. It is vital to research on how to construct terrain data peer-to-peer (P2P) storage model according to its features. In this paper, we present a terrain data P2P storage model according to the pyramid model. In our terrain data P2P storage model, terrain data is...
The peer-to-peer (P2P) systems have many applications due to their virtues: high scalability and low cost. The systems using super-peers (SPs), which deal with all queries, instead of ordinary-peers (OPs), run more efficiently. So how to choose SPs from all peers is a key, but also a difficult problem because of the systems' heterogeneity and dynamic. In this paper a novel mechanism for the selection...
We propose a three-level SuperPeer network (TSN) for file sharing built on a SuperPeer network. The TSN adopts a SuperPeer P2P network capable of providing file management and the structured P2P network capable of searching file as its basic structure. It is required to dynamically reconstruct its network topology according to changes in peer state and file hot. We propose an autonomic, distributed,...
