How to Simulate Line Topology Projects Using MATLAB

To simulate line topology in MATLAB has needs to replicate a line topology includes to positioned nodes in a line and introducing connections among adjacent nodes. In a Line Topology, nodes are associated in a single line, in which each node is associated to its immediate neighbor(s). This topology is usual in simple, linear interaction structures, like chain or bus networks.

Here is a procedure to simulate the line topology in MATLAB.

Steps to Simulate a Line Topology in MATLAB

1. Define the Network Structure
   • Positioned each node in a linear arrangement.
   • Associate each node to its immediate neighbor(s) to create a line.
2. Simulate Data Transmission
   • Execute data transmission among adjacent nodes.
   • Establish latency or packet loss as required to replicate network conditions.
3. Visualize the Topology
   • Generate the nodes and association to demonstrate the line topology.
4. Evaluate Performance Metrics
   • Evaluate the parameters like total data routed, delay, or packet loss via the line.

Example MATLAB Code for Simulating a Line Topology

Here’s a MATLAB script which replicates a line topology with data transmission among adjacent nodes.

% Parameters

numNodes = 6;                     % Number of nodes in the line

nodeSpacing = 10;                 % Distance between adjacent nodes

nodePositions = [nodeSpacing * (0:numNodes-1)’, zeros(numNodes, 1)]; % Position nodes in a line

dataPackets = randi([50, 100], 1, numNodes-1); % Data packets to send to each adjacent node

transmissionDelay = 0.5;          % Delay per transmission (in seconds)

% Plot the line topology

figure;

hold on;

for i = 1:numNodes-1

% Draw lines between each pair of adjacent nodes

plot([nodePositions(i,1), nodePositions(i+1,1)], [nodePositions(i,2), nodePositions(i+1,2)], ‘k–‘);

end

% Plot each node

for i = 1:numNodes

plot(nodePositions(i,1), nodePositions(i,2), ‘bo’, ‘MarkerSize’, 8, ‘DisplayName’, [‘Node ‘, num2str(i)]);

end

xlabel(‘X Position’);

ylabel(‘Y Position’);

grid on;

axis equal;

hold off;

% Step 1: Simulate Data Transmission between Adjacent Nodes

disp(‘Data Transmission Simulation:’);

for i = 1:numNodes-1

fprintf(‘Node %d sends %d packets to Node %d…\n’, i, dataPackets(i), i+1);

pause(transmissionDelay); % Simulate delay

fprintf(‘Node %d received data from Node %d\n’, i+1, i);

end

% Step 2: Display Network Metrics (Example: Total Data Transmitted)

totalDataTransmitted = sum(dataPackets);

disp([‘Total data transmitted along the line: ‘, num2str(totalDataTransmitted), ‘ packets’]);

Explanation of Code

1. Node Positioning and Connections:
   • Nodes are placed in a straight line with equal spacing (nodeSpacing).
   • Every pair of adjacent nodes is associated with a dashed line to create the line topology.
2. Topology Visualization:
   • Nodes are denoted as blue circles, and lines among them shows connections, that generates a linear chain.
3. Data Transmission Simulation:
   • Every node sends data packets to its immediate neighbour that replicates data flow beside the line.
   • Latency is established for each transmission to replicate real-time data transfer.
4. Network Metrics Calculation:
   • The amount of data routed via the line is estimated and showed at the end of the simulation.

Extensions and Variations

1. Bidirectional Communication:
   • Execute bidirectional data transmission by enabling every node to transmit and receive data from both neighbours where it applicable.
2. Introduce Packet Loss or Variable Delays:
   • Incorporate a possibility of packet loss or random transmission latency to generate more realistic scenarios.
3. Evaluate Additional Performance Metrics:
   • Measure the delay, throughput, or packet loss via the line to measure network performance.
4. Dynamic Network Changes:
   • Replicate the accumulation or removal of nodes beside the line to learn the effects on network performance.

Visualization of Data Transmission

To demonstrate the data packets each node transmits to its neighbour, we can utilize a bar plot.

% Plot the number of packets each node sends to its right neighbor

figure;

bar(1:numNodes-1, dataPackets);

xlabel(‘Node Index (Sending Node)’);

ylabel(‘Packets Sent to Next Node’);

grid on;

Advanced Simulation Scenarios

1. Multi-Hop Transmission:
   • Enable nodes to transmit data to non-adjacent nodes by communicating the packets via intermediate nodes that replicate multi-hop communication.
2. Traffic Analysis:
   • Establish to changing traffic loads via the line to measure on how congestion impacts the packet delivery and delay.
3. Fault Tolerance:
   • Replicate the node or connection failures and evaluate on how the network activities is impacted, specifically in environment in which the interaction depends on a single line of nodes.
