为了满足5G及以后时代新兴带宽密集型应用的需求,具有非常大频谱可用性的毫米波(mmWave)频段已被认为是未来无线通信的一个有前途的选择。特别是,在60 GHz载波频率上工作的IEEE 802.11ad/ay是一种备受期待的无线局域网(WLAN)技术,用于支持超高速率数据传输。在本文中,我们描述了ns-3 802.11ad模拟器的新增功能,包括3D障碍物规范、视距计算和基于稀疏集群的信道模型,使研究人员能够在更现实的条件下研究复杂的毫米波Wi-Fi网络部署。与基于确定性光线追踪的信道模型相比,我们还研究了所实现的统计信道模型的性能精度和仿真效率。通过大量的ns-3仿真,结果表明所实现的信道模型在提高仿真效率的同时,在性能评估方面具有良好的准确性。我们还对统计通道模型进行了详细的参数分析,从而了解如何适当地调整模型参数以进一步提高性能准确性。
To address the needs of emerging bandwidth-intensive applications in 5G and beyond era, the millimeter-wave (mmWave) band with very large spectrum availability have been recognized as a promising choice for future wireless communications. In particular, IEEE 802.11ad/ay operating on 60 GHz carrier frequency is a highly anticipated wireless local area network (WLAN) technology for supporting ultra-high-rate data transmissions. In this paper, we describe additions to the ns-3 802.11ad simulator that include 3D obstacle specifications, line-of-sight calculations, and a sparse cluster-based channel model, which allow researchers to study complex mmWave Wi-Fi network deployments under more realistic conditions. We also study the performance accuracy and simulation efficiency of the implemented statistical channel model as compared to a deterministic ray-tracing based channel model. Through extensive ns-3 simulations, the results show that the implemented channel model has the potential to achieve good accuracy in performance evaluation while improving simulation efficiency. We also provide a detailed parametric analysis on the statistical channel model, which yields insight on how to properly tune the model parameters to further improve performance accuracy.
