NeTS: Small: Collaborative: PHY-Informed Networking (PHY-IN): Rethinking Wireless Protocol Design with the Knowledge of PHY

传统上，物理层(PHY)和网络堆栈的更高层的职责相互隔离，导致带宽受限的无线网络的效率严重低下。要弥补这些效率低下的问题，需要重新思考和重新设计无线协议，以便高层和物理层协同工作。本项目探索PHY信息网络(PHY-IN)框架下的三个方案。1)具有冲突通知的载波侦听多路访问(CSMA/CN)机制检测并中止冲突，脱离现有的基于冲突避免(CSMA/CA)的方案，例如802.11。2)基于星座的速率(CBAR)自适应方案跳跃到适合于变化的信道的最佳可行速率。3)重映射方案置换用于重传的比特到副载波分配，以提高其成功的机会。PHY-IN框架有可能影响未来无线网络协议的格局。除了指导本科生和研究生成为独立的研究人员外，这个项目，包括一所EPSCoR大学和一个研究实验室，也将有助于扩大参与和行业合作。

Traditionally, there has been an isolation of responsibilities of physical layer (PHY) and higher layers of the network stack leading to severe inefficiencies in bandwidth-limited wireless networks. Remedying these inefficiencies requires rethinking and redesigning wireless protocols such that higher layers and PHY work in synergy. This project explores three schemes under the PHY-Informed Networking (PHY-IN) framework. 1) Carrier Sense Multiple Access with Collision Notification (CSMA/CN) mechanism detects and aborts collisions, breaking away from the existing collision avoidance (CSMA/CA) based schemes such as 802.11. 2) Constellation BAsed Rate (CBAR) adaptation scheme jumps to the best feasible rate suitable for a varying channel. 3) Remap scheme permutes bit-to-subcarrier assignment for a retransmission to improve the chances of its success. The PHY-IN framework has the potential to impact the landscape of future wireless networking protocols. Apart from mentoring both undergraduate and graduate students into independent researchers, this project, involving an EPSCoR university and a research lab, will also help broaden the participation and industry collaboration.
