Dear Vi Hk

Certainly! Here's an example MATLAB code that demonstrates the implementation of the controller placement algorithm using Antlion optimization and PSO for an SDN network:

###matlab code starts

% Parameters

numControllers = 5; % Number of controllers to be placed

numAntlions = 50; % Number of antlions in the population

maxIterations = 100; % Maximum number of iterations

c1 = 2; % Cognitive coefficient for PSO

c2 = 2; % Social coefficient for PSO

w = 0.7; % Inertia weight for PSO

% Network Topology

% Define your SDN network topology (nodes, links, etc.)

% Fitness Function

fitnessFunction = @(controllers) calculateFitness(controllers, networkTopology);

% Initialization

antlions = initializeAntlions(numAntlions, networkTopology);

controllers = antlions(:, 1:numControllers);

% Antlion Optimization with PSO

bestFitness = Inf;

bestSolution = [];

iteration = 1;
