FOVNET (Fog-based Vehicular Network)

Intelligent Road Safety with Fog Computing

This project implements a vehicular communication system based on Fog Computing, developed and tested using the Eclipse MOSAIC 25.0 simulation framework. The system enables reliable, low-latency data exchange between vehicles (OBUs), Road-Side Units (RSUs), and a Fog node, with the ultimate goal of improving road safety.

For a better understanding of the project please read the article.

🚗 Project Purpose

The aim of this project is to design and simulate a custom multihop forwarding protocol to ensure robust connectivity between vehicles and the Fog server. By leveraging ad hoc V2X communication and central Fog processing, the system is capable of:

• Creating a dynamic awareness map of neighboring vehicles,
• Optimizing forwarding paths based on proximity and hop count,
• Issuing real-time commands such as slow down, stop, or resume,
• Reacting to emergency vehicles in traffic scenarios.

🔧 Technologies and Tools

• Eclipse MOSAIC 25.0 — Co-simulation framework for mobility and communication networks.
• SUMO (Simulation of Urban Mobility) — Used to simulate traffic behavior.
• Java — Main programming language used for OBUs, RSUs, and the Fog node logic.
• Ad hoc Networking (V2X) — Communication model for vehicles and RSUs.

▶️ How to Run It

Requirements

• Installed and configured Eclipse MOSAIC version 25.0
• Linux shell or WSL (for compile.sh script)

Steps to Build and Run

1. Edit the build script compile.sh: Set the following variables:

   BASE_DIR="/path/to/Network-Dir"
   TARGET_DIR="/path/to/eclipse-mosaic/scenario"

2. Compile the project:

   ./compile.sh

3. Run the scenario: From within the Eclipse MOSAIC root directory, execute:

   ./mosaic.sh -s vehApp_1

This will launch the simulation where regular vehicles yield to an emergency vehicle based on messages generated by the Fog.

🔍 Features Demonstrated

• Dynamic neighbor map generation through Beacon and VehInfo messages
• Multihop routing based on proximity and hop optimization
• Emergency reaction through event-driven Fog messages
• Vehicle behavior adapted in real time in a SUMO traffic environment

🧪 Future Work

The following improvements are planned:

• Integration of knowledge-based opportunistic forwarding algorithms.
• Evaluation and filtering of message freshness to prevent outdated data usage.
• Unified message handling via abstract classes (e.g., Message superclass).
• Statistical performance evaluation with metrics such as latency, throughput, and packet delivery using federation output.
