Résumé
<p>Power line communications technology was developed after the establishment of the power distribution network, it is considered to be one of the promising means of data transfer for home networks, and is a medium of shared transmission. Our study was based on the effectiveness of the CSMA/CA method, the collision occurs when the modems transmit at the same time, the transmitters draw the same backoff (a random waiting time) after another transmission. After the backoff, the modems check, before transmitting, that the channel is free to base themselves on the detection of preamble symbols which identify a competing transmission. The proposed simulation approach is based on the estimation of the power level in the channel between the hybrid and default channel listening process. The solution is based on the transfer function used in the modeling</p>
