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

点击翻译按钮获取中文摘要

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.
