Air-Traffic-Controller

Overview

This project is a simulation of an Air Traffic Control (ATC) system using POSIX-compliant C programs. The system includes several processes representing planes, airports, an air traffic controller, passengers, and a cleanup process. Each entity communicates using inter-process communication (IPC) techniques.

Project Structure

The system consists of the following components:

1. Plane Process (plane.c):

   • Simulates passenger and cargo planes.
   • Handles user inputs for plane details such as type, weight, and passenger information.
   • Manages IPC with passenger processes and the air traffic controller.

2. Air Traffic Controller Process (airtrafficcontroller.c):

   • Directs planes to airports and manages their journey.
   • Communicates with plane and airport processes via a single message queue.
   • Logs flight details and handles termination requests.

3. Airport Process (airport.c):

   • Simulates airports with multiple runways.
   • Manages plane arrivals and departures.
   • Ensures planes use the appropriate runways based on their weight.

4. Cleanup Process (cleanup.c):

   • Monitors the system and handles termination requests.
   • Ensures a graceful shutdown of the entire system.

Features

• Simulates both passenger and cargo planes.
• Utilizes multi-threading for airport operations.
• Ensures safe communication between processes using message queues and pipes.
• Includes a logging mechanism for tracking plane movements.

Compilation

To compile the programs, run:

gcc plane.c -o plane.out -lpthread
gcc airtrafficcontroller.c -o airtrafficcontroller.out -lpthread
gcc airport.c -o airport.out -lpthread
gcc cleanup.c -o cleanup.out -lpthread

Execution

1. Start the Air Traffic Controller:

   ./airtrafficcontroller.out

2. Start Airport Processes:

   ./airport.out

3. Start Plane Processes:

   ./plane.out

4. Start Cleanup Process:

   ./cleanup.out

Usage

Each program will prompt the user for the necessary inputs. Follow the on-screen instructions to simulate the operations of the ATC system.
