摘要
为了建立完整的基于Qualnet的无线传感网仿真研究平台,解决Qualnet所集成的物理层模型对扩频系统支持不完善的问题,提出了一种基于信噪比门限的物理层建模方法,并以IEEE802.15.4为例进行了建模和仿真。仿真结果表明,使用这种建模方法建立的模型可以完全发挥扩频系统的性能,使用该模型的无线传感网仿真系统运行正常。
A physical layer modeling strategy based on SINR threshold is proposed to construct a integrated simulation platform for wireless sensor networks in Qualnet. The strategy consummate Qualnet physical layer models for spread-spectrum systems. AIEEE802.15.4 physical layer model is constructed and simulated as an illustration. Simulations show that models constructed using the strategy guarantee the performance of spread-spectrum systems. Wireless sensor network simulation system based on the model works well.
