基于对等计算的分布式时空查询处理系统的设计及应用研究

摘要

采用对等计算技术解决分布式时空查询处理问题,分析并设计了基于对等计算的时空查询处理系统.参与计算的节点通过合理有效的拓扑结构进行组网,整体上对外提供时空查询服务,查询负载被合理地分配到相关节点中,大大增强了系统的鲁棒性和容错性,提高了系统性能和抗毁能力.最后通过应用实例说明系统具有很大的应用价值.%This paper proposed a novel solution which leveraged peer-to-peer computing to accomplish distributed spatio-temporal query processing, and designed a spatio-temporal query processing system based on P2P.Nodes were organized into effective topology and they cooperatively provided spatio-temporal query ability.So query load was distributed among the nodes properly, which greatly reinforced system robustness and fault tolerance and highly enhanced performance and invulnerability.Finally, discussed case studies to illustrate the applications of the system.
