Abstract :
Performance of the IEEE 802.16 e power management is mainly affected by two operating parameters: the minimum sleep interval (T min) and the maximum sleep interval (T max), in sleep-mode operation. To enhance the performance, this letter proposes a new power saving mechanism, which adaptively controls these parameters by considering the request period of each initiation of awakening (Tint)- The numerical analysis and simulation results show that this mechanism can achieve better energy conservation with reasonable response delay of Medium Access Control (MAC) Service Data Units (SDUs) than the standard operation.
