摘要: 认知无线电技术通过动态频谱接入提高了频谱资源利用率。针对动态频谱环境中进行实时流媒体传输缺乏仿真手段,提出了一种基于NS2的视频传输仿真架构,它能够支持实时视频编码、实时播放模拟与跨层优化传输。实验结果证明了仿真架构的正确性。

Abstract: Cognitive radio improves the spectrum utilization by accessing the spectrum dynamically.As lacking of a simulation mechanism for video streaming in dynamic spectrum environment,a NS2 based simulation framework is proposed,it supports real-time video coding,cross layer optimized transmission,and real-time video playing.This framework is validated by the simulation results.
Key words: Network Simulator-version 2(NS2), real-time video, cognitive radio, cross layer optimization
