Abstract

In order to reduce the power consumption of a mobile station and the air interface resources utilization of serving base stations, IEEE802.16e introduced the sleep mode during which a mobile station stops its normal service. By predicting the next downlink inter-packet arrival time, a novel efficient power saving mechanism (PSCI-ED) is proposed in this paper to improve both energy efficiency and packet delay. Simulation results reveal that the proposed mechanism can achieve much better results on reducing the power consumption and the packet delay due to the consideration of the traffic characteristics and rate changes, compared with the sleep mode algorithm recommended by IEEE802.16e.
