A-Prometeus is a comprehensive emergency response system that addresses critical situations, particularly wildfires. One of its standout features is its ability to function independently of internet connectivity due to the use of Mesh networks which allow to distribute the information between chips. It is suitable for deployment in remote rural areas or during wildfire events that disrupt online services. The hardware part of the solution remains low-cost and simple in installation which can be seen on a diagram "The Final Circut" where it's shown how the chip is designed and connected to the street light system including the ability to switch nods (lights) on and of to produce the "wave effect" (available on GitHub). The A-Prometeus system comprises various components, including, microcomputers, chips, software, a graph database, and online capabilities.

The A-Prometeus completes several tasks, some simultaneously and others consequentially. Below it is described on the flowchart, which can be also found on the project's GitHub page.

1. Query to the FIRM and Meteo databases.

These two databases are used to obtain real-time data about fire positions, properties, and meteorological conditions.

2. Proximity and danger levels are computed.

Each node of the graph database representing a street light has the properties of latitude and longitude. The proximity to the fire is computed using the coordinates of the fire and of the street lights. It is computed the danger level using different atmospheric conditions and the proximity property previously computed. The danger level has two uses.

3. Heat Map

A heat map of the region is plotted. It can be easily transmitted to local authorities to complement their reasonings on how to manage safe zones and direct the local population.

4. Light Wave

The danger level is transformed in a frequency for street lights. A light wave will be formed to direct people near or on the streets to the safest zones. The path is chosen through an algorithm that minimizes the total danger level of the path.

Mesh networks

A mesh network is a type of network topology where each device (node) in the network is interconnected, allowing data to be passed from one node to another in a decentralized manner. The infrastructure in our streetlights is interconnected through a mesh network. Each streetlight has a communication range of approximately 100 meters. Importantly, every individual streetlight serves as a node within this mesh network and functions as a router. This design enables us to create an expansive and resilient network.
