NeTS-ProWiN: Practical Use of Channel Information in Multihop Wireless NetworksThe explosion of cellular communications has lead to a tremendous body of work on sophisticated wireless communication techniques many of which require knowledge of wireless channel state information (CSI). However, very little of this work has been applied to wireless networks where nodes communicate over multiple hops and where distributed rather than centralized solutions are required.Taking advantage of this opportunity requires a marriage of physical layer, medium access control, and networking expertise to use CSI to improve network capacity, throughput, and reliability, and to reduce delay. New algorithms and protocols are being developed that span the protocol stack to provide effective sharing of CSI. These techniques are being validated by using a novel, open source, multihop, multiantenna, wireless network testbed - Hydra.Contributions will include:. Development of strategies for using feedback to effectively share CSI.. Development of multiuser channel models, both to aid in the dissemination of CSI and also to facilitate accurate network level simulation of feedback based systems.. Demonstrating the use of CSI to allow practical exploitation of the relay channel at the level of the network.In addition to the usual dissemination of research results through the production of students and scholarly papers, the Hydra prototype itself will be available to other researchers. Since Hydra is open source and based on inexpensive hardware, these outside groups will be able to test and build upon the results from this research program.

NetS-ProWiN：多跳无线网络中信道信息的实际应用蜂窝通信的爆炸式增长导致了有关复杂无线通信技术的大量工作，其中许多技术需要无线信道状态信息 (CSI) 的知识。然而，这项工作很少应用于无线网络，在无线网络中节点通过多跳进行通信，并且需要分布式而不是集中式解决方案。利用这个机会需要结合使用物理层、介质访问控制和网络专业知识。 CSI 可提高网络容量、吞吐量和可靠性，并减少延迟。跨协议栈的新算法和协议正在开发中，以提供 CSI 的有效共享。这些技术正在通过使用新颖的开源、多跳、多天线无线网络测试平台 Hydra 进行验证。贡献将包括：开发利用反馈有效共享 CSI 的策略。开发多用户通道模型，既有助于传播 CSI，又促进基于反馈的系统的精确网络级模拟。演示 CSI 的使用，以实现 CSI 的实际开发除了通常通过学生和学术论文传播研究成果外，Hydra 原型本身也可供其他研究人员使用。由于 Hydra 是开源的并且基于廉价的硬件，因此这些外部团体将能够测试并基于该研究计划的结果。
