- W2390553882 abstract "An energy efficient secondary user was designed based on the spectrum prediction.The frame structure of the secondary user was redesigned,and the prediction slot was added before the sensing slot to select channel for sensing only from the channels predicted to be idle.Consequently,the sensing energy is saved and the energy efficiency is improved compared to the traditional secondary user.It is further found that the energy efficiency is determined by prediction energy,prediction duration,traffic intensity and the number of channels in cognitive radio networks(CRN).Simulation results show that to improve energy efficiency,prediction energy should be controlled less than 32 mW and prediction duration should be cut shorter than 15 ms.Furthermore,increasing traffic intensity and channel amount of the cognitive radio networks improves the energy efficiency of secondary user." @default.
