摘要
随着网格技术和嵌入式系统的发展,传统的软件体系结构和提供服务的方式已经不能满足日益普及的移动设备和嵌入式设备的需求,网格计算的兴起将改变传统的Client/Server和Client/Cluster结构,形成新的Pervasive/Grid(P/G)体系结构。在这种体系结构之下,客户端是各种各样的无线移动设备,而连在网上的各种服务器将组成单一的逻辑上的网格(Grid)。本文以智能交通导航系统为背景,提出一套基于P/G体系结构的移动定位导航系统解决方案。并且提出了基于网格环境MPICH-G2并行平台的交通流量预测计算问题的网格模型,解决了传统交通流预测中效率低、精度差等问题。
With the development of grid technology and embedded system, the traditional software architecture and the way of service providing can not meet the demand of increasingly widespread mobile and embedded device. The rising of grid computing and pervasive computing will push the traditional Client/Server and Client/Cluster structure to an innovative structure, Pervasive/Grid. In this structure, client sides include various wireless mobile devices, and all kinds of servers that are connected to the network consisting of a unique grid logically. On the base of the scheme of Intelligent Transportation Navigation System, this paper provides a P/G-based solution. And this paper also provides a model based on Grid/Globus environment, using the MPICH-G2 message passing library, which can meet practical requirement of solving the problems in traffic flow forecasting, such as low efficiency, low accuracy, etc.
