摘要
提出了一个基于Tapestry的GIS模型。该模型对Tapestry中的代理路由算法进行了改进,提出了对范围查询、动态属性的更新和基于多属性的联合查询3个问题的解决方案。实验证明基于Tapestry的GIS模型具有很好的自组织性、容错性、扩展性,并能很好地实现范围查询、动态属性的更新和基于多属性的联合查询。最后指出了该模型还有待继续研究的问题。
This paper supports a new model of GIS which is based on Tapestry. The model improves the surrogating route algorithms of Tapestry and proposes the ways to deal with range queries, multi-attribute based queries and the updating of dynamic attributes. By experiments, perfect expansibility, self-organization, fault-tolerance are proved to be the attributes of the model, and it can do well in range queries, multi-attribute based queries and the updating of dynamic attributes. Finally, it points out the future works of the model.
