Abstract

This paper presents a P2P approach to the delivery of earth-observation data. Conventional P2P networks can speed up data delivery but suffers the problem of stability when handling spatial data. We design a hybrid CDN-P2P strategy to speed up data delivery while maintaining stability. We tested our strategy in a simulation environment in which performance of data transfer is observed against different bandwidths. The results show that the hybrid approach performs much better than the conventional only-server and only-peers model. Dynamic allocation of peers and predownload are also presented as strategies to address the special needs of spatial data delivery.
