This repository contains the implementation details for the WLFB Car Park Application, a multi-threaded client-server system developed as a core assessment for the CS3004 Network Computing module. The primary objective of this project is to simulate a car park management system that dynamically tracks the number of available spaces as cars enter and leave.
The WLFB Car Park (WCP) system models a car park with two distinct entrances (EntA, EntB) and two exits (ExA, ExB). The system is designed to demonstrate key concepts in network computing, including client-server communication, multi-threading, and concurrency control using locking mechanisms.
Core Functionality:
Client-Server Architecture: The application is built upon a robust multi-threaded client-server model.
Car Park Management: The server maintains the current number of cars in the car park and the available spaces.
The car park is assumed to have five spaces for simplified testing.
Entrances (EntA & EntB):
Each entrance is implemented as a separate client with its own simple integer queue representing waiting cars.
Check_space: Clients can query the server for the current car park space.
Add_car: Clients instruct the server to add a car to the car park (if space is available), removing it from the entrance queue. Cars will queue if the car park is full.
Exits (ExA & ExB):
Each exit is also implemented as a separate client.
Remove_car: Clients instruct the server to remove a car from the car park, reducing the car count by one.
Server:
Manages the car park's state (number of cars) as a shared integer variable.
Responds to client requests (space checks, adding/removing cars).
Locking mechanisms are critically employed to ensure data integrity and thread safety across all client operations.
No user interface is required or implemented.
