Abstract
Now most of the spatial information service applications still adopt the centralized pattern, which brings the network congestion or single point of failure to the side of center server. But the P2P technique takes away the bottleneck in data transmission exists in traditional C/S model by virtue of its multilink self-adaptive mechanism of the data transmission, which has a magnitude meaning for researches on the spatial information service delivering. As the spatial data has the characteristic of the massive volumes and client change the interesting spatial area so frequently that the spatial application efficiency is sharply decreased, the author brought forward a layered P2P architecture of the spatial data interoperation and flexible group mode in P2P network. A mechanism of the layered query queue of the oriented association and the self-adapted cache mode were introduced to adjust the peer loading and the link numbers for the reliable data capture. In this way, we can provide the each peer the rapid data transmission speed, the great data transmission reliability and the better user experience. A prototype was developed and it proved the efficiency of this P2P spatial information service framework. At last the futures of involved techniques and methods are concluded.
