[Abstract]:The rapid development of Peer-to-Peer Network (P2P) technology has opened a new way for the efficient sharing of remote sensing image data.The data transmission between peer and peer terminals can effectively reduce the dependence of data sharing on server and greatly improve the efficiency of data distribution transmission.Because each terminal in peer-to-peer network may store image data in different regions, when it is necessary to share some image data, it is an important problem to select which terminals to transmit which tiles to improve the transmission efficiency.In this paper, we study the efficient sharing of tile data sets between peer-to-peer terminals, and propose a genetic algorithm based tile resource selection method, which can effectively solve the problem of peer-to-peer tile resource selection.
