基于移动代理的分布式仿真建模与分析

Modeling and Analysis of Mobile Agent-based Distributed Simulation System

随着分布式仿真规模的扩大,传统的分布式仿真技术不能完全满足系统需求。利用移动代理的自主性,协调性和智能性等特点,按照RTI接口规范,实现仿真系统功能。首先,分析HLA作为移动代理分布式仿真环境的可行性,指出移动代理在分布式仿真中的优势,然后,构建基于移动代理的邦元管理框架,设计了移动代理邦元运行流程,最后,讨论了在HLA环境中移动代理的时间管理,共享和发布机制等关键问题。构建了基于移动代理的分布式仿真原型系统,并进行了仿真应用测试。

With the extension of distribution simulation, the traditional distributed simulation technology can not fully satisfy the demand of distributed system. Mobile agent is characteristic of autonomy, harmony, intelligence, which may be utilized to realize simulation system function according to RTI(Runtime Infrastructure) interface specification. On the base of analyzing the feasibility of HLA (High Level Architecture) as an environment of mobile agent distributed simulation, the advantages of mobile agent were figured out. Then, a federate management framework was proposed and mobile agent federate circulation flow was designed. Lastly, the key issues were investigated including time management, sharing and publication of mobile agent. Through constructing mobile agent-based prototype system, HLA simulation application was tested.
