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*

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。

Distributed spatio-temporal query processing system based on peer-to-peer computing: design and case study

This paper proposes a novel solution which leverages peer-to-peer computing to accomplish distributed spatio-temporal query processing, and designs a spatio-temporal query processing system based on P2P. Nodes are organized into effective topology and they cooperatively provide spatio-temporal query ability. So query load is distributed among the nodes properly, which greatly reinforces system robustness and fault tolerance and highly enhances performance and invulnerability. Finally, case studies are discussed to illustrate the applications of the system.
