Paper Abstract

Spatial image browse and retrieval in spatial information system are based on centralized server. The limitations are obvious under a concurrent multi-users environment. P2P (Peer-to-Peer) approach takes full advantage of the resources and bandwidth among clients distributed around network in order to offload the centralized server and improve performance of delivery. This paper explores three key issues of forming a spatial image P2P network, the P2P network topology, the organization and identifier of spatial image and a content locating method based on spatial grid index. Then, we design an effective and reliable spatial image delivery system assisted by P2P networks. We have comparatively evaluated our design through requesting an image from World Wind server and our P2P network formed by World Wind clients, which shows a significant improvement of delivery speed.
