Architecture

Figure 1 presents a system view of the COSMOS testbed. It is based on a multi-layered computing system built in a bottom-up manner with commodity components, programmable hardware, and open-source software.

The collection of global testbed services are deployed on a pair of computing clusters located at WINLAB's ORBIT facility in North Brunswick, NJ and Columbia University CS data center (CRF) in West Harlem in New York City, NY.

COSMOS Testbed Architecture [br] Figure 1: COSMOS Architecture

These core services are supporting multiple experimentation domains. As is shown in Figure 1, each of the domains consists of the following components:

The core cloud for the large testbed domain (bed.cosmos-lab.org) is split across two locations in NYC: uptown CU CRF data center and downtown NYU data center at 32 AoA interconnected with the high-speed optical backbone.

In particular, COSMOS includes three types of radio nodes:

  • large (rooftop installed "multi-sector base station" (BS))
  • medium (building side or lightpole-mounted "microcellular BSs")
  • small (fixed or mobile).
