空间数据的广泛应用需要高效的架构来管理,以增加空间数据的可用性。网格betway体育(GridGIS)支持快速的空间数据检索,允许用户在任何地方随时透明地访问数据,容易引起空间负载失衡。该文提出一种基于GridGIS的空间负载平衡算法——TLB-Chord,采用动态负载平衡思想,使用基于Chord算法的树结构,实现了一个空间负载平衡模拟系统,展示了TLB-Chord在GridGIS中更加适用于空间数据。 更多还原

【Abstract】 The wide application of spatial data needs an efficient framework to manage them and increase the availability of spatial data in geographical applications.The emergence of Grid computing coupled with Geographic Information Systems(GIS) provides an excellent framework:GridGIS,which supports fast spatial data retrieval and allows its users to transparently access data from anywhere at any time.GridGIS also causes spatial load unbalancing.This paper presents a new load balancing algorithm(TLB-Chor...
