NS-2数据库接口的研究与实现周雍恺 易 平 蔡继文 田 野 王之旸


摘 要:针对目前对网络仿真运行数据的分析仍然采用文本数据文件输出,手工或自己编程序分析,工作量大,难以处理,提出了一种灵活开放的NS与关系数据库的连接架构,可以直接将仿真运行数据导入至数据库中进行分析。通过一些实例来具体说明用关系数据库分析NS运行结果的优点与方法。通过运用数据库的方法,数据之间的联系能够很好地体现,大大节省了数据分析的工作量,并且能够对仿真结果数据进行多方面、多层次的深入挖掘。

  Abstract:NS-2 is an open source network simulation software which is widely used in research area. But most of the researchers still analyze NS-2’s simulation data manually or by writing some awk scripts, which is usually of heavy workload and hard to deal with the huge amount of data. This paper introduced a flexible and open architecture to connect NS-2 with relational database. NS users could design their own relational model and directly inject the simulation data into database. By adopting the database analyzing method, well embodied the relations among the data, thus the process of analyzing could be time-saving, and multi-level, multi-depth analysis could be archived. ......
