NeTS-ProWiN: Practical Use of Channel Information in Multihop Wireless Networks

Nets-ProWiN：信道信息在多跳无线网络中的实际应用蜂窝通信的爆炸性增长导致了大量关于复杂无线通信技术的工作，其中许多需要无线信道状态信息(CSI)的知识。然而，这些工作很少应用于节点通过多跳通信且需要分布式而不是集中式解决方案的无线网络。要利用这一机会，需要物理层、介质访问控制和网络专业知识的结合，以使用CSI来提高网络容量、吞吐量和可靠性，并减少延迟。正在开发跨越协议栈的新算法和协议，以提供有效的CSI共享。这些技术正在使用一个新颖的、开源的、多跳、多天线的无线网络Tested-Hydra.进行验证。贡献包括：制定使用反馈有效分享CSI的策略。开发多用户信道模型，既有助于CSI的传播，也有助于基于反馈的系统的准确网络级模拟。演示了CSI的使用，以允许在网络层面上实际利用中继通道。除了通常通过学生和学术论文的制作来传播研究成果外，九头蛇原型本身将可供其他研究人员使用。由于九头蛇是开源的，并且基于廉价的硬件，这些外部团队将能够测试和构建来自该研究计划的结果。

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.
