Stimulate wireless sensor nodes in matlab

You can simulate your Wireless Sensor networks using Matlab. As your question regarding implementation is already answered by Professor C.P. Ravikumar. Test-bed implementation (Hardware platform) require different types of sensors for examples BT-Node platform, TelosB sensor node, MICAz 2.4 GHz etc. Each type of sensor has different features and compatible with different platforms. Some of the known implemented platforms used for several projects include:

Accsense

Ambient Systems mesh networks

Atlas

BEAN Project

BTnode

COTS Dust

Fleck

Glacsweb

iSense hardware platform 

Hoarder Board -Open Hardware Design

MeshScape

Mica Mote (Crossbow) 

Newtrax Technologies, Inc

openPICUS - Open Hardware

Particles (Particle Computer) 

PicoCrickets

Redwire Econotag

Sensor Webs

Smart Dust

TIP Mote

Tyndall Motes

Waspmote (Libelium)

Sensor Internet Project

Global Sensor Networks 

 

 #Simple Example of generating the nodes in MATLAB:

Here is example to create node manually in MATLAB.

BeconX=500;

BeconY=500; axes(handles.axes1);

gca; hold on;

hbecon=plot(BeconX,BeconY,'s') set(hbecon,'color','red','LineWidth',8);

Basic part of 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. Kindly check  following Matlab code .

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;
