The COSMOS Testbed – a Platform for Advanced Wireless, mmWave, Edge-cloud, and Optical Experimentation
This talk will provide an overview of the COSMOS testbed (www.cosmos-lab.org), that is being deployed as part of the NSF Platforms for Advanced Wireless Research (PAWR) program, and the supported experiments in advanced wireless, millimeter-wave (mmWave), full-duplex, edge cloud, and optical networking. COSMOS (Cloud-Enhanced Open Software-Defined Mobile-Wireless Testbed for City-Scale Deployment) is being 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 radio links, but also on the system as a whole including algorithmic aspects related to spectrum use, networking, and edge computing.
We will present an overview of COSMOS’ key enabling technologies, which include mmWave radios, software-defined radios, optical/SDN x-haul network, and edge cloud, followed by the deployment and outreach efforts. We will then describe our recently conducted extensive 28 GHz channel measurement campaign including over 40 million power measurements collected from over 2,600 links on 22 sidewalks in 4 different sites. We will also describe experiments on open-access full-duplex wireless and converged optical-wireless x-haul networking with edge cloud that we conducted in the COSMOS testbed.
The COSMOS testbed design and deployment is joint work with the COSMOS team (www.cosmos-lab.org). The mmWave measurement results are based on joint work with Manav Kohli, Tianyi Dai, Angel Daniel Estigarribia (Columbia), Tingjun Chen (Duke), Rodolfo Feick (UTFSM), Dmitry Chizhik, Jinfeng Du, and Reinaldo A. Valenzuela (Nokia Bell Labs). The full-duplex results are based on joint work with Tingjun Chen (Duke), Mahmood Baraani Dastjerdi, Manav Kohli, and Harish Krishnaswamy (Columbia).
