% 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

[mindist, minidx] = sqrt(sum((coords - NrGrid/2).^2,2));
coords(minidx,:) is the closest node to the center.

[mindist, minidx] = min(sqrt(sum((coords - NrGrid/2).^2,2)));
