摘要
基于OPNET平台,构建出一个集中式无线局域网的仿真模型。对比分析了在轮询———应答MAC多址接入协议下,采用不同的物理层特征参数(跳频、直接序列)时,网络性能(吞吐量、媒体接入时延、丢包率)的差异,用以选取最佳解决方案。
With OPNET simulation software,this paper puts forward a simulation model for a centralized wireless LAN.By adopting two kinds of physical layer characteristic(frequency hopping and direct sequence)separately,different network performances(throughput,media access delay,data dropped)under a poll-response MAC protocol are given,so as to find a suitable solution.
