    The IEEE 802.16j standard introduces Relay Station(RS) based on the IEEE 802.16e standard.RS sleep mode is essential for power saving.The parameters have great impact on the effect of RS sleep mode,namely average energy consumption and average frame delay.In this paper,the system models for the energy consumption and the average frame delay affected by RS sleep mode are built using statistics.By analyzing the parameters,an improved algorithm that dynamically changing parameters based on traffic stream are proposed.The average energy consumption and average frame delay are analyzed by simulation results at last of the paper.
