基于对等计算的分布式时空索引模型建立与整体框架研究
Modeling and framework of P2P-based distributed spatio-temporal index
摘要
Abstract
This paper creatively proposed P2P-based spatio-temporal index. It studied how to model this problem and how to build whole framework. And the model and framework covered historical index and future index. The model was based on space division, and described space partition, service node and spatio-temporal objects. The whole framework was two-tier structure, and was able to support new request under distributed environment. It consisted of querying, building and maintaining protocals. And then used 3 cases to show valid of the model. Finally, it studied the performance of the whole framework on the system developed by authors. The results show the frame is able to fullfil the access demond in distributed environment.关键词
