Wireless communication and networking is increasingly prevalent in everyday life. This project focuses on exploiting the substantial number of degrees of freedom that are increasingly available at the physical layer to design and build multihop wireless networks with enhanced capacity, robustness, and usability. Our central objective is to identify how to best leverage these tradeoffs and experiment with complementary medium access control (MAC) protocols that are capable of doing so.Our approach is an integrated one that focuses on cross-layer algorithm design and implementation. The focus is three fold: one, the development of a multi-hop wireless network prototype testbed - Hydra; two, the design and implementation of adaptive physical layer (PHY) modulation and coding schemes that significantly increase PHY flexibility; and three, the design and implementation of novel medium access control (MAC) algorithms that efficiently exploit the flexibility offered by next-generation PHYs. Our approach crosses the boundaries between both the physical layer and the networking layers and between theory and practice.Perhaps the greatest impact of our work comes from designing and building a working prototype. This allows us to generate results that are extremely well grounded in physical reality, taking us away from the simulation-oriented approach that currently dominates wireless networking. These results will help to enable more effective wireless networks, especially those where data takes multiple wireless hops. We will disseminate our results through the production of students as well as the usual publication venues.

无线通信和网络在日常生活中越来越普遍。 该项目的重点是利用物理层越来越多的自由度来设计和构建具有增强容量、稳健性和可用性的多跳无线网络。 我们的中心目标是确定如何最好地利用这些权衡，并尝试能够实现这一点的补充介质访问控制 (MAC) 协议。我们的方法是一种集成方法，专注于跨层算法设计和实现。 重点有三方面：一是开发多跳无线网络原型测试平台——Hydra；二、设计和实现自适应物理层（PHY）调制和编码方案，显着提高PHY灵活性；第三，新型媒体访问控制（MAC）算法的设计和实现，可有效利用下一代 PHY 提供的灵活性。 我们的方法跨越了物理层和网络层之间以及理论和实践之间的界限。也许我们工作的最大影响来自于设计和构建工作原型。 这使我们能够生成非常基于物理现实的结果，使我们摆脱目前主导无线网络的面向模拟的方法。 这些结果将有助于实现更有效的无线网络，特别是那些数据需要多个无线跳的网络。 我们将通过学生的作品以及通常的出版场所传播我们的成果。
