Abstract: NS-2 is one of the most widely used network simulation softwares. But there are few researches on hardware-in-loop simulation based on NS-2. A new Hardware-In-Loop simulation platform based on NS-2 (HIL-NS) was proposed, by mapping real data flows to the simulation networks. Based on the description of HIL-NS platforms architecture in detail, key technologies to implement this platform were discussed. The simulation results of wireless MAC protocol 802.11b in Vehicle Ad-hoc NETwork (VANET) show that the results of HIL-NS platform highly coincide with those of NS-2. And the proposed platform can get more direct real-time output of the performance while supporting traditional data analysis.
Key words: hardware-in-loop simulation, NS-2, network simulation, real-time, performance evaluation
摘要: NS-2是一款广泛使用的网络仿真软件,但针对它的半实物仿真方法研究较少。针对这一问题,通过实际实时业务流与虚拟仿真网络的映射,提出并实现一种新的基于NS-2的网络半实物仿真HIL-NS平台。在详细描述HIL-NS平台构成基础上,讨论并解决了其实现的关键技术。在车载通信网络(VANET)实例下对802.11b无线MAC协议性能进行仿真,结果表明HIL-NS平台不但能与NS-2纯仿真的结果趋势保持高度一致性,并且在支持传统数据分析的同时,能有更直观的仿真性能实时输出。
