Arul - why not just add a third column to the clusterHeads and clusterNodes matrices. From the link you provided, just modify the code to something like the following
clusterData = cell(size(X,2),1);
for k=1:size(clusterData)
clusterData{k}.clusterHead = [X(k) Y(k) E(k)];
clusterData{k}.clusterNodes = [];
end
for k=1:size(S,2)
x = S(k).xd;
y = S(k).yd;
energy = S(k).ENERGY;
minDist = Inf;
at = 0;
for u=1:size(X,2)
dist = sqrt((x-X(u))^2+(y-Y(u))^2);
if dist<minDist
minDist = dist;
at = u;
end
end
if at>0
clusterData{at}.clusterNodes = ...
[clusterData{at}.clusterNodes ; [x y energy] ];
end
end
Note that the above is untested, and assumes that you have created an E energy array in the manner that you created the X and Y arrays i.e.
X(cluster)=S(i).xd;
Y(cluster)=S(i).yd;
E(cluster)=S(i).ENERGY; % <-- add this line

k sir thank you , but according to author which ever has the higher residual energy that's going to be the cluster head and even in basic LEACH algorithm also saying the same thing. so please sir try this one please.
Don't ignore this code please tell the mistake in my code please...
