Performance of Cooperative Relaying Techniques Over Different Fading Channels in Industrial Wireless Sensor Networks

Abstract

In the dynamic and disorganized industrial environment monitoring and controlling, strict reliability of applications and reducing delays is a major challenge for wireless communication. The industrial wireless sensor network is a very useful technique, but the efficiency of the sensor node’s energy and data packet from one node to the other node is very low. That is, the destination node goes into the outage. In this paper, AF-DF releasing techniques are used to deal with this problem. Therefore, the performance of wireless sensor networks can be optimized. To see its performance, the BER of AF-DF is compared to the BER of the direct communication link. BER performance has been observed in Nakagami-m fading and Rayleigh feeding channels, and the results of simulations show that the BER is decreasing by using these techniques.
