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 platform's 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.
