SCOPE Scenarios
These are a set of RF cellular scenarios to use with the Colosseum wireless network emulator. Scenarios have been designed in three different urban setups:
Rome, Italy
Boston, MA, US
Salt Lake City, UT, US (POWDER scenario)
For the Rome and Boston scenarios, the locations of the base station reflect real cell tower deployments taken from the OpenCelliD database. For the POWDER scenario, locations mirror the coordinates of the rooftop base stations deployed in the POWDER testbed in Salt Lake City.
Different versions of the above scenarios have been created for different numbers of base stations and users, different distances from the base stations users are deployed, and different mobility speeds of the users.
Available distances between users and base stations:
Close: users are deployed within 20 m from the base stations
Medium: users are deployed within 50 m from the base stations
Far: users are deployed within 100 m from the base stations
Available user mobility speeds:
Static: users do not move for the whole duration of the scenario
Moderate: users move at 3 m/s
Fast: users move at 5 m/s
Note
These scenarios cluster nodes in groups of 5. This means that nodes 1-5 are emulated to be closer to each other than they are to the other nodes of the scenario. The same holds for the remaining nodes, i.e., nodes 6-10, 11-15, 16-20, 21-25, 26-30, 31-35, 36-40, 41-45, and 46-50.
Rome Scenarios
The Rome scenario captures the dynamics of the city center of Rome, Italy. A total of 50 nodes are involved: 10 BSs and 40 UEs (4 UEs assigned to each BS randomly scattered around it). This is one of the densest scenarios in Colosseum and covers an area of 0.5 km².
