Concept: Infrastructure as an Aries Agent In our system, the infrastructure plays a vital role as an Aries agent. But what does that mean exactly?

What is Aries? Aries is an open-source project that provides a set of tools and libraries for building self-sovereign identity (SSI) solutions. It enables secure, peer-to-peer communication between parties while ensuring privacy and data ownership.

Infrastructure as an Aries Agent In our context, the infrastructure refers to the network of physical elements such as road infrastructure, traffic lights, and other smart components deployed within an environment. By equipping these elements with Aries agent capabilities, we empower them to participate actively in the communication network.

Integration with FHWA Mobile App Agent One of the key interactions in our system is between the infrastructure and the FHWA (Federal Highway Administration) mobile app agent deployed in vehicles. When a new instance of the FHWA mobile app agent starts up in a vehicle, it initiates a connection process with the infrastructure.

Multi-Use Invitation The infrastructure exposes a multi-use invitation, essentially a shared access point for connecting with the infrastructure. This invitation allows multiple entities, such as vehicles running the FHWA mobile app agent, to establish connections with the infrastructure.

Dedicated Connection Despite being a single common invitation, each application connecting to the infrastructure through this invitation obtains a dedicated connection. This means that once established, the FHWA mobile app agent has its unique channel of communication with the infrastructure.

Benefits of Dedicated Connection By having a dedicated connection, the FHWA mobile app agent can seamlessly communicate with the infrastructure. This dedicated channel ensures reliability, security, and efficiency in message transmission between the vehicle and the infrastructure.

Communication with Vehicles With these dedicated connections in place, the infrastructure gains the capability to communicate effectively with vehicles within the network. It can send messages, receive data, and coordinate actions, thereby enabling advanced functionalities such as traffic management, safety alerts, and more. By treating infrastructure as an Aries agent and establishing dedicated connections with vehicles, we create a robust and efficient communication framework that enhances the overall capabilities and intelligence of the transportation system.

Steps to Run:

1. Run the setup script in the main folder to install dependencies.

./setup

If using Windows follow steps in setup.txt.

Also run

pip install -r requirements.txt

in the main folder.

eventlog Save the CSV file folder path as an environment variable CSV_PATH

2. In the docker folder there is manage script to build the docker images =======

main

If in Windows use Git Bash to run Shell scripts.

3. To run you have two options: A. Run the program on the port 8054 of your public IP. Your public IP should allow inbound traffic on port 8054. B. Open the port 8054 using ngrok.

For A

Run

./manage start-demo

For B

I. Create .env file in ngrok folder II. NGROK_AUTH_TOKEN=authtoken from ngrok III. Run

./start-ngrok.sh

If in Windows use Git Bash to run Shell scripts.

IV. In the docker folder Run

./manage start-dev

For both when

is an indication the program is running.

Note: To stop the program Run

./manage stop

To remove all containers and volume data

Run

./manage rm

4. Open a new tab to scripts folder. Go to invitation folder. Run

For Windows

python create-invitation.py

For Linux

python3 create-invitation.py

For enabling s3 Create .env file and provide ACCESS_KEY and SECRET_KEY provided for infrastructure S3 bucket

5. Go to multicast folder There are 3 scripts for testing I. Multicast: For sending complete data by selecting number of rows to send II. Mutlicast Cyclic: Continously send data until explictly stopped III. Mutlicast Events: Send data in range of the latitude and longtitude of the agent

For I

Run

python multicast_observer.py

NOTE

If you run rm to remove docker container re-run the invitation program in scripts/invitation to generate new invitation and reset the old link.
