基于NS-2的多接口多信道仿真模型扩展研究

摘要

基于现有802.11x系列标准对无重叠多信道技术的广泛支持,分析以该系列标准为基础的多接口多信道(MIMC)无线网络在低层协议(数据链路层和物理层)的仿真需求,阐述现有NS-2仿真软件对MIMC仿真模型支持的不足,从现有扩展模型的实现方案中总结基于NS-2进行MIMC扩展的基本思路与要求,对现有多接口多信道NS-2扩展研究进行分类,并给出相关扩展模型的对比分析.%Based on the wide support of 802.1 1x series standards to orthogonal mutli-channel technology,this paper introduces the simulation requirement in wireless networks,based on multi-interface multi-channel(MIMC),for lower layer(data link and physical layers) protocols.The simulation shortage for MIMC model support in NS-2 is summarized.Then the basic methods and principles for MIMC extensions to NS-2 are elaborated based on some existing schemes.The classification and analyses of extensions are illustrated and some contrastive analyses about MIMC models are given at length.
