软件无线电为研究人员提供了一个完美的平台来试验当前和未来的无线通信系统。然而，特别是对于通信协议的益处在很大程度上取决于系统架构必须满足的非功能性要求（即时间行为）。在本文中，我们分享了我们的经验，一个灵活的SDR框架命名为虹膜。我们提出了一个实现的发送和等待自动重传请求（ARQ）协议，以及一个虚拟的网络驱动程序组件，结合虹膜，形成我们的软件定义的无线网络测试床的核心。为了验证测试床的实际适用性并评估协议的性能，我们正在进行端到端的吞吐量和延迟基准测试。
Software defined radios provide a perfect playground for researchers to experiment with current and future wireless communication systems. However, the benefits, especially for communication protocols, largely depend on non-functional requirements (i.e. temporal behavior) that have to be met by the system architecture. In this paper, we share our experience with a flexible SDR framework named Iris. We present an implementation of a Send-and-Wait Automatic Repeat reQuest (ARQ) protocol as well as a virtual network driver component which, in conjunction with Iris, form the core of our software defined radio networking testbed. To verify the practical suitability of the testbed and to evaluate the performance of the protocol, we are conducting end-to-end throughput and delay benchmarks.
