论文摘要
MMWave系统的基本要求是最多几毫秒的多个Gbps的峰值数据速率和订单的潜伏期。但是，在压力条件（如迁移率和人类阻塞）下，高度定向的MMWAVE链接易受频繁的链接失败的影响。在这些条件下，多跳路由可以实现可靠和稳健的性能。在本文中，我们考虑了多跳的毫米波（MMWave）无线系统，并提出主动的路线改进方案，在动态场景下尤为重要。首先，我们考虑AODV型协议，并提出了一种跨层方法，该方法将MAC层的部门通信与网络层的按需多跳路由集成在一起。接下来，我们考虑背压路由协议，并使用定期的Hello状态消息来增强此协议。提供了基于IEEE 802.11AD标准的系统级仿真结果，以确认对ADOV型和背压路由协议的主动路线完善的好处。
Fundamental requirements of mmWave systems are peak data rates of multiple Gbps and latencies of the order of at most a few milliseconds. However, highly directional mmWave links are susceptible to frequent link failures under stress conditions such as mobility and human blockage. Under these conditions, multi-hop routing can achieve reliable and robust performance. In this paper, we consider multi-hop millimeter wave (mmWave) wireless systems and propose proactive route refinement schemes that are particularly important under dynamic scenarios. First, we consider the AODV-type protocols and propose a cross-layer approach that integrates sectorized communication at the MAC layer with on-demand multi-hop routing at the network layer. Next, we consider Backpressure routing protocol, and enhance this protocol with periodic HELLO status messages. System-level simulation results based on the IEEE 802.11ad standard are provided that confirm the benefits of proactive route refinement for the ADOV-type and Backpressure routing protocols.
