How to Simulate Proactive Protocols Projects Using MATLAB

To simulate proactive routing protocols in MATLAB has usually includes to generating a network simulation scenarios in which proactive protocols such as Optimized Link State Routing (OLSR), Destination-Sequenced Distance Vector (DSDV), or any other protocol are executed and validated in numerous network conditions.

Here’s a basic procedures on how to simulate proactive routing protocols in MATLAB:

Steps to Simulate Proactive Routing Protocols in MATLAB

1. Define the Network Topology:
   • Configure the network nodes with positions such as 2D or 3D coordinates.
   • Describe the communication range of each node (this is utilized to generate the network links).
   • We can utilize random placement or certain arrangements according to the study.

Example:

numNodes = 10;

nodePositions = rand(numNodes, 2) * 100;  % Random positions in a 100×100 area

commRange = 20;  % Communication range

2. Initialize the Routing Table:
   • For a proactive protocol, all nodes sustain a routing table to every other node in the network.
   • Adjust routing tables according to node positions (and communication range if nodes are in range).

Example of routing table initialization:

routingTable = inf(numNodes, numNodes);  % Infinite distance initially

for i = 1:numNodes

for j = 1:numNodes

if i ~= j

dist = norm(nodePositions(i, 🙂 – nodePositions(j, :));

if dist < commRange

routingTable(i, j) = dist;  % Direct link distance

end

end

end

end

3. Implement the Proactive Routing Algorithm:
   • Select a proactive protocol such as OLSR, DSDV, or any other protocol.
   • Execute the algorithm logic to occasionally interchange routing information among the nodes.

For instance, in DSDV, all nodes occasionally broadcasts routing table updates, and distances are modernized according to received information.

Example (simple distance vector update):

function routingTable = updateRoutingTable(routingTable, newUpdates, nodeID)

for i = 1:length(newUpdates)

for j = 1:length(newUpdates)

% Update routing table with the new distances

if routingTable(nodeID, j) > routingTable(nodeID, i) + newUpdates(i, j)

routingTable(nodeID, j) = routingTable(nodeID, i) + newUpdates(i, j);

end

end

end

end

4. Simulate Data Transmission:
   • Utilize the routing table to replicate the transmission of information among nodes.
   • Select an origin and destination node, and observe the path using the routing table.

Example:

srcNode = 1;

dstNode = 7;

path = findPath(routingTable, srcNode, dstNode);  % Implement path finding based on routing table

5. Update Routing Tables Periodically:
   • Proactive protocols update routing tables occasionally, so we required replicating this in a loop with time steps.

Example:

for t = 1:simTime

for node = 1:numNodes

% Get updates from neighboring nodes and update routing table

newUpdates = receiveUpdatesFromNeighbors(node);

routingTable = updateRoutingTable(routingTable, newUpdates, node);

end

end

6. Analyse Results:
   • After the simulation, evaluate the performance of the protocol.
   • We can measure the parameters such as average path length, routing overhead, end-to-end delay, or packet delivery ratio.

Example of performance metrics calculation:

avgPathLength = mean(nonInfPaths);  % Calculate average path length for all source-destination pairs

routingOverhead = totalControlPackets / totalDataPackets;  % Example metric

7. Visualization (Optional):
   • Utilize MATLAB’s plotting functions to envision the network topology, routing paths, and key parameters.

Example of basic network topology visualization:

figure;

plot(nodePositions(:, 1), nodePositions(:, 2), ‘bo’);

hold on;

for i = 1:numNodes

for j = i+1:numNodes

if routingTable(i, j) < inf

plot([nodePositions(i, 1), nodePositions(j, 1)], [nodePositions(i, 2), nodePositions(j, 2)], ‘r-‘);

end

end

end
