On the Performance of Cooperative Transmission Schemes in Industrial Wireless Sensor Networks

Abstract

This paper studies the performance of six transmission schemes, namely single-hop, multihop, selective decode-and-forward, amplify-and-forward, incremental decode-and-forward (IDF), and incremental amplify-and-forward (IAF) schemes. For a fair comparison, these schemes are constrained in terms of maximum outage probability and end-to-end throughput. In this paper, we investigate the impact of propagation channel conditions including both line-of-sight and non-line-of-sight environments by exploiting Nakagami-m fading channel. Our simulation results show that, by utilizing a return channel, the IDF and IAF cooperative schemes achieve better performance than the other schemes in most cases.
