NeTS: Medium: Collaborative Research: Leveraging Physical Layer Advances for the Next Generation Distributed Wireless Channel Access Protocols

该项目旨在解决如何最大限度地提高访问无线介质的效率这一根本问题。近年来，出现了新的信息论解决方案，由于技术进步，其中一些现在可以实施。此外，长期根深蒂固的概念，如半双工，也受到了挑战。事实证明，通过物理层策略和信号处理的结合，全双工系统确实是可行的。这些发展从根本上改变了时空资源是什么的概念。这些发展需要彻底重新定义和评估本项目所述的有效利用问题。多年来，物理层社区和礼宾界的发展是并行的，有些孤立的。通过将这两个领域的广泛专业知识结合在一起，该项目设想在接入层无线网络方面取得根本性进展。核心挑战是如何尽可能有效地利用“空间”和“时间”这两种稀缺资源。此外，分布式操作、信道衰落、时变的信道条件以及传输机会和决策的快速时间尺度加剧了问题。该项目有可能在媒介获取科学方面取得变革性的进展。

This project aims at addressing the fundamental problem of how to maximize the efficiency of access to the wireless medium. In recent years, new information-theoretic solutions have emerged, some of which can now be implemented due to technological advances. Also, long engrained notions, such as half duplex, are being challenged. It has been shown that through a combination of strategies at the physical layer and signal processing, full duplex systems are indeed feasible. These developments have radically altered the very notion of what a spatio-temporal resource is. These developments have necessitated a thorough redefinition and appraisal of the problem of efficient access as addressed in this project.Over the years, developments have taken place in parallel and somewhat in isolation in the physical layer community and in the protocol community. By bringing together a broad-spectrum of expertise from both areas, this project envisages fundamental advances in wireless networking at the access layer. The core challenge is how to use the scarce resources of 'space' and 'time' as efficiently as possible. In addition, distributed operation, channel fading, time-varying channel conditions, and fast time-scales of transmission opportunities and decisions, exacerbate the problem. This project has the potential of making a transformative advancement in the science of medium access.
