Collaborative transmission schemes in industrial Wireless Sensor Networks

Abstract

This paper analyzes the outage probability, energy efficiency, energy efficiency-spectral efficiency trade-off, through-put performance, energy efficiency-throughput gain trade-off and derives the optimal transmission power of Single-hop, Multi-hop, Decode-and-Forward (DF) and Incremental Decode-and-Forward (IDF) schemes in order to find out what extent collaborative communication can save energy consumption for successful transmission. Based on the Nakagami-m fading channel, this paper provides a generalized impact of energy saving in both Line-of-Sight (LOS) and Non line-of-sight (NLOS) environments. Simulation results show that IDF protocol, allowing assistant node help relay information, achieves better performance than the other techniques.
