Draw a line between nodes which are conected.

 num1 = input('Enter the no of nodes you want to consider in your WSN'); 
      radius = 30;
      i=num1;   
  Adj = zeros(i,i);
         for i= 1:num1
             X = randi([0 200],1,num1);
             Y = randi([0 200],1,num1);
         end
      X      
      Y  
plot(X1,Y1,'gx','LineWidth',4,'MarkerSize',15)

can we give numbering to nodes and create a line to show that they are connected. Let assume all nodea are connected

Find the attached code below

total_number_of_nodes = 10;

for i=1:1:total_number_of_nodes
    S(i).xd=rand(1,1)*500;                             
    S(i).yd=rand(1,1)*500;                            
    S(i).ID=i;                                        
 
    
    
    plot3(S(i).xd,S(i).yd, 0 ,'mo',...                           % Plot all the nodes in 3 dimension 
    'LineWidth',1.5,...                                          % Size of the line
    'MarkerEdgeColor','k',...                                    % The color of the outer surface of the node. Currently it is set to black color. "k" stand for black. 
    'MarkerFaceColor',[1 1 0],...                                % The color of the inside of the node. Currently it is set to yellow color. "[1 1 0]" is a code of yellow color
    'MarkerSize',10), ...
     box on
xlabel(' Length (m)')                                            % X-label of the output plot
ylabel(' Width (m)')                                             % Y-label of the output plot
zlabel(' Height (m)')                                            % Z-label of the output plot
title(' Random deployment of the sensor nodes in the network')   % Title of the plot
grid on                                                          % Activate the grid in background of the plot
% Hold figure 1
hold on
text(S(i).xd+0.01, S(i).yd+0.01, 0+0.01,["Node", num2str(i)]);   % To show ID number of each node

end
