Paper Abstract

The unprecedented amount and multiple applications of remote sensing image data have created a strong need for efficient data transmission. Commonly used in the transmission of various types of data, peer-to-peer (P2P) opens up new possibilities for the transmission of remote sensing image data. A considerable amount of work has been done toward the transmission of remote sensing data by using map tiles for fast online browsing. However, issues concerning the transmission of original image data require more volume and flexibility, which is indispensable in the application of remote sensing images. According to the spatial and band characteristics of remote sensing images, an approach using image subset blocks (ISBs) is proposed for P2P transmission of remote sensing image data. The method improves efficiency in two ways: transmitting ISBs on demand to reduce unnecessary transmission and using a P2P method to break the bandwidth bottleneck of the central server. The results of the performance evaluation reveal that compared with the traditional transmission method that uses the central server, the proposed method considerably enhances the efficiency to approach the level of general P2P file transmission.
