摘要
针对现有分布式地理信息系统数据处理的瓶颈问题,利用Web服务和移动Agent技术解决GIS领域的动态服务问题,详细阐述GIS软件的系统结构和动态服务模型,介绍移动Agent和构件服务等相关实现技术,给出基于智能决策的Agent迁移策略及其算法描述。最后通过模拟仿真实验,验证了该迁移策略和算法的有效性。
In regard to the bottleneck problem in present distributed geographical information system data processing,this paper applies technologies of web service and mobile Agent to solve the dynamic service problem in the GIS field.It elaborates GIS software system structure and its dynamic service model,presents the relative implementation technologies of mobile Agent,component service and so on,and puts forward the intelligent-decision-based Agent migration strategy as well as its algorithmic description.An emulation experiment is conducted in the end to verify the effectiveness of that migration strategy and algorithm.
