论文摘要
富含频谱的毫米波（MMWave）频率有可能减轻无线和蜂窝算子已经在经历的光谱紧缩。但是，与低下6 GHz频段中传统的无线通信相比，由于大多数物体（例如人体）的波长较小，造成了额外的路径损失（最高20dB），这会完全打破MMWAVE链接。此外，MMWave链接的沟通范围有限。在本文中，我们求助于网络层解决方案，以证明多跳路由在减轻阻塞问题和扩展MMWave频段的通信范围方面的好处。为此，我们开发了一个逐行的多路路由协议，该协议可以找到每个目的地的一个主要和一个备份，以确保在极端压力条件下可靠且稳健的通信。基于IEEE802.11AD规格的系统级仿真表明，所提出的路由协议提供了可靠的端到端吞吐量性能，同时满足延迟要求。
The spectrum-rich millimeter wave (mmWave) frequencies have the potential to alleviate the spectrum crunch that the wireless and cellular operators are already experiencing. However, compared with traditional wireless communication in the sub-6 GHz bands, due to small wavelengths most objects such as human body, cause significant additional path losses (up to 20dB), which can entirely break the mmWave link. Also, mmwave links suffer from limited range of communication. In this paper, we resort to network layer solutions to demonstrate the benefits of multi-hop routing in mitigating the blockage issue and extending communication range in mmWave band. To this end, we develop a hop-by-hop multi-path routing protocol that finds one primary and one backup next-hop per destination in order to guarantee reliable and robust communication under extreme stress conditions. System-level simulations based on the IEEE802.11ad specifications demonstrate that the proposed routing protocol provides a reliable end-to-end throughput performance, while satisfying the latency requirements.
