  • In the 802.16e system, when multiple Mobile Stations (MS) with real-time services enter sleep mode, the efficiency of power saving is impacted by the competition of the data scheduling in the overlapping listening windows. This paper analyzes the impaction and proposes an enhanced sleep mode management scheme. The proposed scheme tries to make the listening windows of different MS lie dispersedly and balance the system load among OFDM frames by adjusting the start time of sleep mode of the new connection. The simulation result shows the proposed scheme not only improves the energy efficiency but also decreases the signaling overhead as well as improves the QoS of the network.
