P2P空间矢量数据索引网络路由机制的研究与实现
Study and Implementation of Routing Scheme of P2P Spatial Vector Data Indexing Networks
摘要
Abstract
With the popularity of geographical information systems, more and more users want to access to spatial on-line services and data. P2P technology has provided sufficient computing and service capability for vector geographic data processing, the routing efficiency of indexing networks is one of the principle problems in P2PGIS system. In this paper, based on the existing theoretical model, the effective and load balancing P2P spatial vector geography data indexing network is studied and implemented, which expanded and modified JXTA routing protocol scheme by adopting the structured P2P network protocol-Chord and integrating distributed hash table (DHT) technology. The experiment results show that the vector geography data transmission efficiency in the P2P indexing network is higher than that in the centralized scenario.关键词
