How can i move one node or (n) nodes to anothor location in Each time period ?

        clear ; clc; close all;
        Num_nodes = 50; 
        Range = 16; % Determine the transmision range.
        X_position = [5 56 90 73 10 75 30 75 15 15 20 85 55 88 5 2 30 95 65 95 25 20 40 74 65 44 30 45 85 20 65 45 50 95 30 80 65 60 30 45 95 85 70 2 55 55 42 75 35 10];
        Y_position = [5 25 50 70 90 85 1 25 50 70 99 95 5 25 55 80 90 85 10 34 55 80 90 5 35 56 75 99 5 40 60 75 90 15 40 60 74 93 15 40 65 75 99 20 45 65 20 45 64 30];

        figure; clf ;hold on;          xlabel('X-axis ');          ylabel('Y-axis ');

        for i = 1:Num_nodes
                 plot(X_position(i), Y_position(i),'o','markersize',15,'Color','m','linewidth',1); 
                 text(X_position(i), Y_position(i), num2str(i));
                 axis([1,100,1,100]); % draw the nodes inside the figure
             for j = 1:Num_nodes
                 distance_nod = sqrt((X_position(i) - X_position(j))^2 + (Y_position(i) - Y_position(j))^2);
                 if distance_nod <= Range && i ~= j 
                     connection_matrix(i, j) = 1; % To know the joins between nodes according to the transmision range.
                     line([X_position(i) X_position(j)], [Y_position(i) Y_position(j)], 'LineStyle', '-.'); 
                     grid on;
                 else
                     connection_matrix(i, j) = inf; % There is no a link
                 end
             end
        end

How can I move a single node or a set of nodes ( in Each time period) from their current position to another location but not far from their original location, and must be that the move node connect to the node that has become within the transmission range after moving to new position.

% selct nodes to move
movenodes = [46 26 45 40] ;
dx = 0.3;  % move by this along x 
dy = 0.5 ; % move by this along y 

X_position(movenodes) = X_position(movenodes)+dx ;
Y_position(movenodes) = Y_position(movenodes)+dy ;
