how to create a 4*4 cell-grid structure in wsn using matlab and randomly deploy nodes in it.please help.

I am creating a wsn structure wth 4*4 cell grids.I have used the following code to create the 4*4 cell-grid structure but now i have to randomly deploy 100 nodes in them.how could it be done?please help.

maNrGrid = 4;                                 % Number Of Grids

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

maNrGrid = 4;
coords = rand(100,2) * maNrGrid + 1;

The K'th sensor is located at (coords(K,1), coords(K,2)), and each of those will be a value from a hair over 1 to a hair less than 5.

scatter(coords(:,1),coords(:,2));
set(gca, 'XTick', 1:maNrGrid+1, 'YTick', 1:maNrGrid+1)
grid on
