摘要
文中针对目前基于时分多址复用接入方式的无线供电传感网频谱利用率不足,影响系统吞吐性能的问题进行了研究和分析。考虑结合频谱复用和相继干扰消除技术提升吞吐性能。对基于两种技术的系统最大化吞吐问题,提出了一种基于列生成方法的有效问题求解算法。通过仿真试验,发现结合两种技术的网络与基于时分多址复用方式的网络相比,吞吐性能提升了30%左右。
The spectrum efficiency is not enough by Time-division-multiple-access（TDMA） in wireless powered sensor network（WPSN）, which causes the system throughput performance is not high. In this paper, we consider combining the techniques of spectrum multiplexing and successive interference cancellation to analyze the system throughput. We solve the problem efficiently based on the column generation algorithm. Through the simulation test, it is found that the network with the two technologies improves the throughput performance by 30%, compared with the network based on TDMA.
