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.

传统上，物理层（PHY）和网络堆栈的较高层的责任隔离，导致带宽受限无线网络的严重效率低下。纠正这些效率低下需要重新思考和重新设计无线协议，以便在协同作用中较高的层和PHY工作。该项目探讨了PHY信息网络（PHY-IN）框架下的三个方案。 1）载波使用碰撞通知（CSMA/CN）机制检测和中止碰撞，从现有的避免碰撞（CSMA/CA）中脱离碰撞（例如802.11）。 2）基于星座的速率（CBAR）适应方案跳至适合不同通道的最佳可行率。 3）重新启动方案列出了位到鞋业的分配中，以重新提高其成功机会。 PHY-IN框架有可能影响未来无线网络协议的景观。除了指导本科生和研究生进入独立研究人员外，该项目涉及EPSCOR大学和研究实验室，还将有助于扩大参与和行业的合作。
