毫米波（mmWave）通信技术可以使用定向天线在小范围内实现高达几吉比特/秒的数据速率。为了在大区域中实现高数据速率无线连接，需要多跳路由协议。毫米波链路的速率自适应性和定向天线的使用为路由协议设计带来了挑战和机遇。在本文中，我们提出了一个最佳地理路由协议（OGRP）和一个附带的分布式定向介质访问控制（MAC）协议。我们进一步研究了如何优化中继的选择，以最大限度地提高流的吞吐量，并最大限度地减少网络资源使用的流，考虑MAC开销。通过平衡跳数和每跳吞吐量，建议OGRP优于现有的贪婪地理路由和机会路由协议。
Millimeter-wave (mmWave) communication technologies can achieve up to several gigabit/sec data rate over a small range, using directional antenna. To enable high data rate wireless connectivity in a large area, a multi-hop routing protocol is needed. The rate-adaptiveness of mmWave link and the use of directional antenna brings both challenges and opportunities for routing protocol design. In this paper, we propose an Optimal Geographic Routing Protocol (OGRP) and an accompanying distributed directional medium access control (MAC) protocol. We further study how to optimize the selection of relays to maximize the flow throughput and minimize the network resources used by a flow, considering the MAC overheads. By balancing the number of hops and the per hop throughput, the proposed OGRP outperforms the existing greedy geographic routing and opportunistic routing protocols.
