Hi..
could i have a look at your code or examples. so that i can try to modify and make it work with the GUI ?. perhaps after doing so i might get and new idea of how to implement mine. because now that you talk about sensor networks, i also need my program to sense when something is too close to a base station, for example. if there are 2 base stations but there is a third which is not needed and is making contact with the other two, it could be deleted or disable or something.
thanks
hi can u plz send me pseudocode for pegasis?? i need it for my thesis work under wireless sensor networks

Hi ellobazo,
What do you mean by "to move it around"? Do you want something with a graphical user interface?
I'm currently working on a project where I randomly place nodes in a two-dimentions space. It's useful in Wireless Sensor Networks simulations. Let me know if this is useful and I can share it with you (it's a very simple code)
Hi ellobazo,
Wireless Sensor Networks (WSN) is different than the Cellular Networks as I mentioned earlier.
A WSN is composed of a large number of sensor nodes that communicate using a wireless medium (air).
The sensor nodes are deployed randomly in the environment to be monitored.
The sensor nodes distributed in ad hoc structure.
In WSN there is no base station and not all nodes hear each other.
The WSN is a multi-hop network.
Basic part of my code is to randomly place the sensor nodes in the given space then connecting each two nodes if the distance between them less than or equal to the communication radius. Please check Matlab code below.
clear;
noOfNodes = 50;
rand('state', 0);
figure(1);
clf;
hold on;
L = 1000;
R = 200; % maximum range;
netXloc = rand(1,noOfNodes)*L;
netYloc = rand(1,noOfNodes)*L;
for i = 1:noOfNodes
plot(netXloc(i), netYloc(i), '.');
text(netXloc(i), netYloc(i), num2str(i));
for j = 1:noOfNodes
distance = sqrt((netXloc(i) - netXloc(j))^2 + (netYloc(i) - netYloc(j))^2);
if distance <= R
matrix(i, j) = 1; % there is a link;
line([netXloc(i) netXloc(j)], [netYloc(i) netYloc(j)], 'LineStyle', ':');
else
matrix(i, j) = inf;
end;
end;
end;
hi.. m doing thesis in wireless sensor network.. ...how to create sensor node forwarding circle ...plz me some basic code

Hi ellobazo,
plz tell how to create circle every node given range...plz reply me
