在下面的Matlab代碼中,使用節點N=10
,您將以概率P= .25
將隨機選取的節點標記爲紅色節點。Matlab,找到不參與邊緣的節點?
nodeN = [];
nodeM = [];
N=input('No. of Nodes:');
P=input('probability of cluster head : ');
R=input('range of cluster head: ')
data = rand(N,2) % Randomly generated n no. of nodes
x = data(:,1);
y = data(:,2);
plot(x,y,'b*')
hold on
index = (rand(N,1) <= P); %# to choose cluster head out of N nodes with probability P
selected = data(index,:) % nodes which are now cluster head
length(selected) % no. of nodes which are cluster head
not_selected = data(~index,:) % remaining nodes which would be cluster members(out of N nodes)
length(not_selected) % no. of remaining nodes
plot(x(index),y(index),'r*'); % cluster head will be colored red in figure
for i=1:length(selected);
for j=1:length(not_selected);
dist_ij = sqrt(sum((selected(i,:)- not_selected(j,:)).^2)) % distance between selected cluster heads and remaining nodes
if(dist_ij<=R)
nodeN = [nodeN; selected(i,:)]
nodeM = [nodeM; not_selected(j,:)]
end;
end;
end;
if size(nodeN,1)~=0 && size(nodeN,2)~=0 && size(nodeM,1)~=0 && size(nodeM,2)~=0
X1=[nodeN(:,1)' ; nodeM(:,1)']
Y1=[nodeN(:,2)' ; nodeM(:,2)']
plot(X1,Y1)
hold on
end;
如何找到它們不在範圍內,不要使用紅色節點中的任意邊緣並繪製這些節點綠色那些剩餘的藍色節點矩陣?
非常感謝我的朋友,它工作正常 – gurwinder 2009-12-16 12:24:05
它解決了我的問題,但你能告訴我這個bitar在代碼中做了什麼? – gurwinder 2009-12-16 18:00:16
