Abstract
a wierless sensor network consists of spatially distributed autonomous sensor to cooperatively monitor physical or environmental conditionsm such as tempreture, sound, vibration, pressure, motion or pollutants. diffirent approaches have used for simulation and modeling of SN (sensor network) and WSN. Traditional approaches consist of various simulation tools based on different languages such as C, C++ and Java, In this paper , MATLAB (7.6) Simulink was used to build a complete WSN system. Simulation procedure includes building the hardware acchitecture of the transmitting nodes, modeling both the communication channel and the receiving master node architecture. Bluetooth was chosen to undertake the physical layer communication with respect to different channel parameters (i.e. signal to Noise ratio, Attenuation and Interference). the simulation model was examined using diferent topologies under various conditions and numerous results were collected. this new simulation methodology proves the ability of the simulink MATLAB to be a useful and fexible approach to study the effect of diferent physical layer parameters on the performence of wierless sensor network.
