| 摘 要： | 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。

| Abstract: | Explore the method of reasonable plans of sensing interval to solve the issue.We deduce the function of the discovery delay and the energy consume as the increase of the sensing interval in multi-channel condition.And also we explain the selection problems of the interval and the channel number through the simulation,which will be a great contribution to the realization of the CRSN. |
