CloudSim Scheduling Algorithms

This project simulates scheduling in a cloud computing environment using CloudSim. Multiple scheduling algorithms are implemented, allowing for flexibility in assigning tasks (cloudlets) to virtual machines (VMs).

Features

• Implemented scheduling algorithms:
  • Round Robin
  • First-Come-First-Serve (FCFS)
  • Shortest Job First (SJF)
  • Genetic Algorithm
  • Ant Colony Optimization (ACO)

How It Works

1. Create Datacenter and VMs: A datacenter with a pool of VMs is initialized.
2. Cloudlets: Multiple cloudlets (tasks) are created, each representing a unit of workload.
3. Scheduling: The user can select an algorithm to schedule cloudlets to VMs.
4. Algorithms: Based on the selected algorithm, the cloudlets are assigned to VMs in an optimized manner.
5. Simulation: The CloudSim engine runs the simulation and outputs the scheduling results.

Algorithms Usage

Enter the algorithm to be used: (roundrobin, fcfs, ant, genetic, sjf): genetic

Choose any of the following algorithms:

• roundrobin: Round-robin scheduling.
• fcfs: First-Come-First-Serve scheduling.
• ant: Ant Colony Optimization scheduling.
• genetic: Genetic Algorithm-based scheduling.
• sjf: Shortest Job First scheduling.

Requirements

• Java 8 or higher
• CloudSim library

Setup

1. Clone the repository:

   git clone https://github.com/Ravikisha/CloudSim-Examples.git

2. Add the CloudSim library to your project.
3. Compile and run the project:
