| Abstract: | To enhance energy efficiency of battery powered wireless access devices,the power efficiency for sleep operation is researched with established the Markov chain model of the sleep mode in IEEE802.16e,and the relationship is analyzed between the power consumption and the mean delay.Then,a dynamic algorithm is proposed to adapt randomization traffic of mobile station.Theoretical analysis and the NS2 simulations results show that the proposed algorithm can save more energy of the terminal. |
