How to create a wireless sensor network in matlab?

Numerous procedures are involved in the process of developing a Wireless Sensor Network (WSN) simulation in the MATLAB environment. It encompasses specifying the network layers, simulation of the sensor node activity, and application of interaction protocols. MATLAB has robust visualization and computational abilities. Specifically when the MATLAB is integrated with its Simulink model-related design environment, it provides an appropriate platform for simulations.

Based on the development of a fundamental WSN simulation in MATLAB, we offer an explicit instruction below. Creation of sensor nodes, simulation of their sensing and interaction processes, and visualization of network will be included in the following instance:

Step 1: Define Network Parameters

First, the parameters of your WSN like the dimension of the simulation area, the total count of nodes, and other important parameters have to be specified.

numNodes = 50; % Number of sensor nodes

areaSize = [100, 100]; % Size of the area [width, height]

commRange = 25; % Communication range of each node (in meters)

Step 2: Generate Node Positions

Within the defined area, allocate the sensor nodes in a random manner. Note that every node will have a coordinate that is named as X and Y.

nodePositions = rand(numNodes, 2) .* areaSize;

Step 3: Simulate Sensor Node Behavior

In order to simplify, enable the simulation of activity in which every node sensing its platform over time. To encompass particular sensing inference in terms of the objectives of your simulation, you can extend this simulation process.

% Example of a simple periodic sensing simulation

sensingInterval = 1; % Time in seconds between each sensing action

simulationTime = 60; % Total simulation time in seconds

for t = 0:sensingInterval:simulationTime

% Placeholder for sensing logic

% For example, each node could measure temperature

temperatures = 20 + (5*rand(numNodes, 1)); % Random temperatures between 20 and 25 degrees

end

Step 4: Implement Communication Between Nodes

Regarding the range of communication, every node transmits data to all the other nodes. Consider the simulation of this fundamental communication. This instance will verify for nodes that are within the range of communication but will not transmit real data.

for i = 1:numNodes

for j = 1:numNodes

if i ~= j

distance = norm(nodePositions(i,:) – nodePositions(j,:));

if distance <= commRange

% Nodes i and j can communicate

% Placeholder for communication logic

end

Step 5: Visualize the Network

To visualize the network along with the range of communication and nodes, utilize the plotting functions of MATLAB.

figure;

hold on;

for i = 1:numNodes

plot(nodePositions(i,1), nodePositions(i,2), ‘bo’); % Plot nodes

viscircles(nodePositions(i,:), commRange, ‘Color’, ‘g’, ‘LineStyle’, ‘–‘); % Plot communication range

end

xlim([0 areaSize(1)]);

ylim([0 areaSize(2)]);

xlabel(‘X Position (m)’);

ylabel(‘Y Position (m)’);

hold off;
