I have placed the super node in wsn in a specific position I want to add mobility with it across x-axis?

Xm=100 %value of x plane. 100=1 ym=100 %value of y plane. 100=1 Super.s_nodex=xm*0.5; super.s_nodey=ym*1.1;

I think one for loop is needed but I don't know how to add that anyone help me please?

Hey @Asad Ullah, To add mobility to a super node in a Wireless Sensor Network (WSN) across the x-axis, you can use a loop to update the x-coordinate of the super node over time. This can simulate movement across the x-axis. Here's a basic approach to achieve this in MATLAB:Steps to Simulate Mobility:

1. Define Parameters: Set the initial position and movement parameters for the super node.
2. Loop for Movement: Use a loop to update the position of the super node over time.
3. Plot the Movement: Visualize the movement to see the trajectory.

i have attached a simple example to demonstrate this below:

% Parameters
Xm = 100; % x dimension of the area
Ym = 100; % y dimension of the area
super.s_nodex = Xm * 0.5; % Initial x position of the super node
super.s_nodey = Ym * 0.5; % Initial y position of the super node
step_size = 1; % Step size for each movement
num_steps = 100; % Number of steps to move

% Create a figure for plotting
figure;
hold on;
axis([0 Xm 0 Ym]);
xlabel('X-axis');
ylabel('Y-axis');
title('Super Node Mobility');

% Plot initial position
plot(super.s_nodex, super.s_nodey, 'ro', 'MarkerSize', 10, 'DisplayName', 'Super Node');
legend;

% Simulate mobility across the x-axis
for step = 1:num_steps
    % Update x position
    super.s_nodex = super.s_nodex + step_size;
    
    % Check if the super node goes out of bounds and reverse direction if needed
    if super.s_nodex > Xm
        super.s_nodex = Xm;
        step_size = -step_size; % Reverse direction
    elseif super.s_nodex < 0
        super.s_nodex = 0;
        step_size = -step_size; % Reverse direction
    end
    
    % Plot the updated position
    plot(super.s_nodex, super.s_nodey, 'ro', 'MarkerSize', 10);
    pause(0.1); % Pause for a short time to visualize movement
end
