matlab代码加载“lab1data.txt”文件,设置距离阈值为225米,在flooding路由协议中,每个传感器 节点都可以向其225米半径范围内的所有邻居发送数据包,从首节点开始发送数据包,一旦所有节点收到数据包,数据包转发 立刻停止计算上述条件下所需的跳数

以下是可以实现上述功能的 MATLAB 代码:
```matlab
% Load data from file
data = load('lab1data.txt');
% Set distance threshold
threshold = 225;
% Initialize variables
numNodes = size(data, 1);
distances = zeros(numNodes, numNodes);
nextHop = zeros(numNodes, numNodes);
% Calculate distances between nodes
for i = 1:numNodes
for j = 1:numNodes
if i == j
distances(i, j) = 0;
else
distances(i, j) = norm(data(i,:) - data(j,:));
end
end
end
% Find neighbors for each node
neighbors = cell(numNodes, 1);
for i = 1:numNodes
for j = 1:numNodes
if distances(i, j) <= threshold
neighbors{i} = [neighbors{i} j];
end
end
end
% Initialize queue with first node
queue = [1];
% Flood data to all nodes
while ~isempty(queue)
currentNode = queue(1);
queue(1) = [];
for i = 1:length(neighbors{currentNode})
neighborNode = neighbors{currentNode}(i);
if nextHop(1, neighborNode) == 0
nextHop(1, neighborNode) = currentNode;
queue = [queue neighborNode];
end
end
end
% Calculate number of hops
numHops = max(nextHop(1,:));
% Display result
disp(['Number of hops: ' num2str(numHops)]);
```
注意:这只是一个简单的实现,实际应用中可能需要考虑更多的因素。
