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

NetTS-ProWiN：多跳无线网络中信道信息的实际应用蜂窝通信的迅速发展导致了大量关于复杂无线通信技术的工作，其中许多技术需要无线信道状态信息（CSI）的知识。然而，很少有这项工作已被应用到无线网络中的节点进行多跳通信，而不是集中式的解决方案是requires.Taking利用这一机会需要一个婚姻的物理层，介质访问控制，和网络的专业知识，使用CSI，以提高网络容量，吞吐量和可靠性，并减少延迟。正在开发新的算法和协议，其跨越协议栈以提供CSI的有效共享。这些技术正在通过使用一种新颖的、开源的、多跳的、多天线的无线网络测试平台- Hydra进行验证。制定利用反馈有效分享CSI的战略。多用户信道模型的开发，既有助于CSI的传播，也有助于基于反馈的系统的精确网络级仿真。演示CSI的使用，允许在网络的水平上的中继信道的实际开发。除了通常的研究成果，通过生产的学生和学术论文的传播，九头蛇原型本身将提供给其他研究人员。由于Hydra是开源的，并基于廉价的硬件，这些外部团体将能够测试和建立在这个研究计划的结果。

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.
