摘要

分析了中断概率、能源效率、能源效率-频谱效率权衡、吞吐量性能、能源效率-吞吐量增益权衡,并推导出单跳、多跳、DF(译码转发)和IDF(增量译码转发)方案的最优传输功率,以找出协同通信在多大程度上可以节省能源以成功传输。基于Nakagami-m衰落信道,本文给出了在视距(LOS)和非视距(NLOS)环境下节能的一般影响。仿真结果表明,IDF协议允许辅助节点帮助中继信息,比其他技术具有更好的性能。

Collaborative transmission schemes in industrial Wireless Sensor Networks
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.
