Abstract:
This talk will provide an overview of the COSMOS testbed, that will be deployed as part of the NSF Platforms for Advanced Wireless Research (PAWR) program, and of one of the first testbed experiments that will focus on full-duplex wireless.
COSMOS (Cloud-Enhanced Open Software-Defined Mobile-Wireless Testbed for City-Scale Deployment) will be deployed in West Harlem (New York City) by Rutgers, Columbia, and NYU in partnership with NYC, CCNY, U. Arizona, IBM, and Silicon Harlem. It targets the technology “sweet spot” of ultra-high bandwidth and ultra-low latency, a capability that will enable a broad new class of applications including augmented/virtual reality and cloud-based autonomous vehicles. Realization of such high bandwidth/low latency wireless applications involves research not only on faster radio links, but also on the system as a whole including aspects such as spectrum use, networking, and edge computing. Hence, the key enabling technologies will include software-defined radios, mmWave radios, optical/SDN x-haul network, edge cloud, and testbed control and management software.
One of the first COSMOS pilot experiments will focus on full-duplex (FD) wireless, since FD communication, namely, simultaneous transmission and reception on the same frequency channel, can substantially improve spectrum efficiency. Within the Columbia Full-duplex Wireless: From Integrated Circuits to Networks (FlexICoN) project, we have been focusing on Integrated Circuit (IC) implementations that are appropriate for mobile and small-form-factor devices. We will present the FlexICoN Gen-1 FD transceiver that has been integrated in the ORBIT testbed. Then, we will present the FlexICoN Gen-2 FD transceiver and the obtained experimental results. We will also present analytical results regarding rate gains when considering these IC-based FD implementations, as well as results regarding scheduling in heterogeneous networks with both FD and legacy half-duplex users. Both the Gen-1 and Gen-2 transceivers will be integrated in the COSMOS testbed to allow experimental evaluations of FD-related algorithms at the higher layers.
The COSMOS testbed design and deployment is joint work with the COSMOS team (www.cosmos-lab.org). The full-duplex results are based on joint works with Tingjun Chen, Mahmood Baraani Dastjerdi, Jelena Diakonikolas, Jin Zhou, Javad Ghaderi, and Harish Krishnaswamy.
