通过合理设计频谱感知间隔优化。在多信道条件下,理论推导了单频谱机会发现情况和多频谱机会发现情况的平均机会发现时间及能耗关于感知间隔的函数,并通过仿真分析说明了感知间隔选择问题和信道数目对感知速度的影响问题,为网络实用提供了理论基础。
Through rational design spectrum sensing interval optimization. Under multi-channel conditions, the average opportunity discovery time and the energy consumption perceptual interval function of single-spectrum opportunity discovery and multi-spectrum opportunity discovery are deduced theoretically. And by the simulation analysis, it is shown that the perception interval selection problem and the number of channels influence the perceived speed The impact of the problem for the network to provide a practical basis for the theory.
