摘要
本文针对基于对等网络的空间数据索引方法展开综述,将当前的P2P空间数据索引方法分为4大类:基于分布式哈希表、树结构、Delaunay三角网结构和基于距离的P2P空间索引方法。分别对每类的研究内容和相关技术进行详细论述,然后对各类查询方法的效率、维护代价和负载均衡情况等相关指标进行对比,最后进行了总结和展望。
In this paper,it reviewed the P2P-based spatial data indexing methods.The current P2P spatial data indexing methods was divided into four main categories： the methods based on distributed hash table,tree structure,delaunay triangulation and spatial distance.Then,the research including search methods,load balancing methods and maintenance methods and other relevant technologies was discussed separately for each class in detail.Comparison was performed between query efficiency,maintenance costs and load balance.Finally,this paper was summarized further.
