Traditionally, there has been an isolation of responsibilities ofphysical layer (PHY) and higher layers of the network stack leading tosevere inefficiencies in bandwidth-limited wirelessnetworks. Remedying these inefficiencies requires rethinking andredesigning wireless protocols such that higher layers and PHY work insynergy. This project explores three schemes under the PHY-InformedNetworking (PHY-IN) framework. 1) Carrier Sense Multiple Access withCollision Notification (CSMA/CN) mechanism detects and abortscollisions, 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 fora varying channel. 3) Remap scheme permutes bit-to-subcarrierassignment for a retransmission to improve the chances of its success.The PHY-IN framework has the potential to impact the landscape offuture wireless networking protocols. Apart from mentoring bothundergraduate and graduate students into independent researchers, thisproject, involving an EPSCoR university and a research lab, will alsohelp broaden the participation and industry collaboration.

传统上，在带宽有限的无线网络中，构成了身体层（PHY）（PHY）的责任（PHY）和较高的网络堆栈领先的Tosevere效率低下的责任。纠正这些效率低下需要重新思考并设计的无线协议，以使较高的层和PHY Works Insynergy。该项目探讨了Phy-informednetworking（PHY-IN）框架下的三个方案。 1）载波在通知（CSMA/CN）机制检测和流产的载体访问中，从现有的避免碰撞（CSMA/CA）方案（例如802.11）中断。 2）基于星座的速率（CBAR）适应方案跳至最佳可行速率合适的通道。 3）重新映射方案列入了位到垫片，以进行重新启动以提高其成功的机会。PHY-IN框架有可能影响景观offuture Wireless网络协议。除了指导大学生和研究生为独立研究人员外，涉及EPSCOR大学和研究实验室的ThisProject还将拓宽参与和行业的合作。
