Wireless network testbeds are important for realistic, at-scale experimental evaluation of new radio technologies, protocols and network architectures. The NSF Platforms for Advanced Wireless Research (PAWR) COSMOS (“Cloud enhanced Open Software defined MObile wireless testbed for city-Scale deployment”) advanced wireless testbed is being deployed in New York City with technical focus on ultra-high-bandwidth and low-latency wireless communications with tightly coupled edge computing, and emphasis on millimeter-wave (mmWave) radio communications and dynamic optical switching. The COSMOS testbed already supports at-scale experimentation of novel advanced wireless broadband and communication technologies in both sub-6 GHz and mmWave frequency bands in West Harlem in New York City, which is representative of a densely populated urban environment. The testbed provides a mix of fully programmable software-defined radio (SDR) nodes for flexible wireless experimentation. It also includes novel 100 Gbps+ fiber backhaul interconnected with a software-defined network (SDN) switching fabric for minimum latency and flexibility in setting up experimental network topologies. The remote accessibility of COSMOS lowers the barrier for experimentation in the area of radio and wireless technology and thus improves education and research productivity. The goal of this tutorial is to provide an introduction to COSMOS testbed management framework OMF and measurement library OML and main technological capabilities. Thereby, it will allow community members that have not been using the testbed to use it for their future research and educational activities.
The first part of Session I will focus on the SDR aspects, where attendees will learn the basics of testbed usage and the OMF testbed management framework. These include how to manage reservations, image the nodes, orchestrate their experiments and collect measurements. Participants will be able to experiment with SDR-based wireless examples.
The second part of Session I will focus on the optical aspects, where attendees will learn how to use Mininet-Optical. Mininet-Optical was developed as part of the COSMOS and COSM-IC projects and adds optical network emulation and simulation capabilities to Mininet to support software emulation of optical and packet-optical networks, including modeling of optical transmission effects and impairments.
The first part of Session II will focus on the SDR aspects at mmWave frequencies, where attendees will learn the basics of the 28 GHz dual polarized, 64-element, 4 IC phased array antenna modules (PAAMs) developed by IBM Research and deployed in COSMOS. Attendees will also learn the basics of the Sivers 60 GHz through channel sounding demos and XY table mobility experimentation. The second part of Session II will focus on the optical aspects, using real hardware of the COSMOS testbed. Attendees will view a live experiment which uses the testbed to test various optical topologies.
