To simulate Zone Routing Protocol (ZRP) in MATLAB, it is a hybrid routing protocol which integrates proactive and reactive techniques for efficient routing in wireless ad hoc networks. The proactive approach is utilized in a defined local zone, since the reactive approach is utilized for communication outer the zone. In MATLAB, replicate the ZRP which include dividing the network into zones, executing both proactive (intra-zone) and reactive (inter-zone) routing protocols, and evaluating the the overall routing behaviour.
Here is a high level guide on how to simulate the Zone Routing Protocol (ZRP) in MATLAB:
Steps to Simulate ZRP in MATLAB
- Define Network Topology
- Initiate by describing a set of nodes signifies the network, with each node allocated to a random position. Each node will have a zone in terms of a predefined radius.
Example of defining nodes and their positions:
numNodes = 10; % Number of nodes
networkArea = 100; % Size of the area (e.g., 100×100 meters)
nodePositions = rand(numNodes, 2) * networkArea; % Random positions of nodes
zoneRadius = 20; % Define the radius of each zone (in meters)
- Determine Node Connectivity
- Each node can interact with other nodes in its communication range. Describe the links among nodes using the distance among them and the communication range.
Example of estimating the distances among nodes and describing connectivity:
communicationRange = 30; % Communication range (in meters)
adjacencyMatrix = inf(numNodes); % Initialize adjacency matrix with infinite distances
% Calculate distances and establish links within communication range
for i = 1:numNodes
for j = i+1:numNodes
distance = norm(nodePositions(i,:) – nodePositions(j,:));
if distance <= communicationRange
adjacencyMatrix(i,j) = distance; % Set link cost (distance)
adjacencyMatrix(j,i) = distance; % Symmetric link
end
end
end
- Zone Formation
- Each node describes its zone by classifying that nodes fall in the zone radius. Interior the zone, proactive routing is implemented, since for nodes outer the zone, reactive routing is utilized.
Example of identifying nodes within each zone:
zoneTable = cell(1, numNodes); % Cell array to store zones for each node
for i = 1:numNodes
for j = 1:numNodes
if i ~= j
distance = norm(nodePositions(i,:) – nodePositions(j,:));
if distance <= zoneRadius
zoneTable{i} = [zoneTable{i}, j]; % Node j is within node i’s zone
end
end
end
end
- Implement Proactive Intra-Zone Routing (e.g., DSDV)
- Within each zone, a proactive routing protocol is utilized, like Destination-Sequenced Distance Vector (DSDV) or Optimized Link State Routing (OLSR). Nodes sustain a routing table with latest information concerning other nodes in their zone.
Example of proactive routing table generation:
function routingTable = proactiveRouting(adjacencyMatrix, zoneNodes)
% Basic distance-vector approach for intra-zone routing
numNodes = length(zoneNodes);
routingTable = inf(numNodes); % Initialize with infinite distances
for i = 1:numNodes
for j = 1:numNodes
if i ~= j
routingTable(i, j) = adjacencyMatrix(zoneNodes(i), zoneNodes(j));
else
routingTable(i, j) = 0; % Distance to itself is 0
end
end
end
end
- Implement Reactive Inter-Zone Routing (e.g., AODV)
- For communication external to the zone, a reactive routing protocol such as Ad hoc On-Demand Distance Vector (AODV) is utilized. Nodes will begin a route discovery process to identify a path to the destination by flooding route requests (RREQ).
Example of reactive route discovery:
function route = reactiveRouting(adjacencyMatrix, src, dst, communicationRange)
numNodes = size(adjacencyMatrix, 1);
visited = false(1, numNodes);
queue = [src]; % Breadth-first search queue
parent = zeros(1, numNodes); % Track the path
while ~isempty(queue)
currentNode = queue(1);
queue(1) = []; % Dequeue the next node
if currentNode == dst % Destination reached
route = [dst]; % Trace back the path
while parent(currentNode) ~= 0
route = [parent(currentNode), route];
currentNode = parent(currentNode);
end
return;
end
% Explore neighbors within the communication range
for neighbor = find(adjacencyMatrix(currentNode,:) < inf)
if ~visited(neighbor)
queue = [queue, neighbor]; % Enqueue
parent(neighbor) = currentNode;
visited(neighbor) = true;
end
end
end
route = []; % No route found
end
- Simulate Data Transmission
- According to the ZRP framework, intra-zone communication utilizes proactive routing, since an inter-zone communication utilize reactive routing. Data is routed from an origin to a destination according to the route exposed.
Example of prioritizing the routing mechanism and routing data:
srcNode = 1;
dstNode = 10;
if any(zoneTable{srcNode} == dstNode) % Check if destination is within the same zone
% Use proactive routing
intraZoneNodes = zoneTable{srcNode};
routingTable = proactiveRouting(adjacencyMatrix, intraZoneNodes);
path = intraZoneNodes(routingTable == min(routingTable));
else
% Use reactive routing
path = reactiveRouting(adjacencyMatrix, srcNode, dstNode, communicationRange);
end
if ~isempty(path)
disp([‘Route from ‘, num2str(srcNode), ‘ to ‘, num2str(dstNode), ‘: ‘, num2str(path)]);
else
disp(‘No route found’);
end
- Evaluate ZRP Performance
- After replicating ZRP routing, measure the parameters like average path length, routing overhead, packet delivery ratio, or end-to-end delay. These parameters will supports you to evaluate on how efficiently ZRP transmit packets among nodes.
Example of calculating average path length:
totalPathLength = 0;
pathCount = 0;
for i = 1:numNodes
for j = i+1:numNodes
if any(zoneTable{i} == j)
% Use proactive routing
intraZoneNodes = zoneTable{i};
routingTable = proactiveRouting(adjacencyMatrix, intraZoneNodes);
path = intraZoneNodes(routingTable == min(routingTable));
else
% Use reactive routing
path = reactiveRouting(adjacencyMatrix, i, j, communicationRange);
end
if ~isempty(path)
totalPathLength = totalPathLength + length(path);
pathCount = pathCount + 1;
end
end
end
avgPathLength = totalPathLength / pathCount;
disp([‘Average path length: ‘, num2str(avgPathLength)]);
- Visualize the Network Topology
- Envision the network and the routes seized by the nodes. MATLAB plotting tools can supports you to demonstrate the node positions, connections, and routes.
Example of visualizing the network:
figure;
plot(nodePositions(:,1), nodePositions(:,2), ‘bo’); % Plot nodes
hold on;
% Plot the links between nodes
for i = 1:numNodes
for j = i+1:numNodes
if adjacencyMatrix(i,j) < inf
plot([nodePositions(i,1), nodePositions(j,1)], …
[nodePositions(i,2), nodePositions(j,2)], ‘r-‘);
end
end
end
