The objective of CityTwin is to realize the simulation of a digital twin system in the context of the smart city. In particular, we want to realize a system that is able to capture and represent in digital format the behavior of the various entities present within the city.

• Within the simulation, there will be two types of nodes: Mainstay and Resource.
• Mainstay nodes are the backbone of the entire system.
• Resource nodes represent abstractions of sensors, actuators, or more complex entities.
• The user can view the current state of the system, the data history, and any statistics.
• The user has the ability to interact with the system via GUI (E.g.: Intervention after the detection of a fire).

• Scala + SBT
• Akka
• MongoDB
• Docker

• Scala 3.3.0
• Java openjdk 17.0.7
• SBT 1.x
• Docker
• Docker Compose

Linux:

• unzip

Windows:

• Powershell
• tar

First of all, start the persistence service:

docker compose build
docker compose up

Then start the rest of the system in another terminal:

On Linux:

./scripts/startup.sh

On Windows:

./scripts/startup.bat
