I have used the following code to create a wsn virtual structure with 4*4 grid-cells and have deployed 100 nodes in it. Each cell is headed by a cluster-head which is in center of the cell i.e their are a total of 16 cluster-heads.Now the whole wsn area is also headed by a single "Area-header" which is in the center of the whole wsn area. Now,how will the cluster-heads collect the information from the nodes of their respective cells? Please help.

 % WSN Grid structure with 4*4 cells made
NrGrid = 4;                        
x = linspace(0, 100, NrGrid+1);
[X,Y] = meshgrid(x);
figure(1)
plot(X,Y,'k')
hold on
plot(Y,X,'k')
hold off
set(gca, 'Box','off', 'XTick',[], 'YTick',[])
axis square                                          
% grid formation ends
% Nodes deployment started
NrGrid = 4;                                     
coords = rand(100,2) * NrGrid + 1;
scatter(coords(:,1),coords(:,2));
set(gca, 'XTick', 1:NrGrid+1, 'YTick', 1:NrGrid+1)
grid on                                            
% Nodes deployment ends
%All good upto here
%cluster head selection on basis of most near to the center
[XC, YC] = ndgrid(1/2:NrGrid+1/2, 1/2:NrGrid+1/2); 
center_idx = zeros(NrGrid, NrGrid);
k=16;
for K = 1 : numel(XC)
  xc = XC(K);
  yc = YC(K);
  dists = sqrt((coords(:,1)-xc).^2 + (coords(:,2)-yc).^2);
  [mindist, minidx] = min(dists);
  center_idx(k) = minidx;
  end
%cluster head selection ends
energy(1:100) = sqrt(7) /2E7;    % Energy given to all the nodes around 0.5 joules
