Abstract

This paper targets to investigate the interaction between IEEE 802.16e scheduling algorithms and sleep-mode operations. To achieve high energy efficiency, an energy-efficient scheduling architecture is first proposed. Based on this architecture, a state transition mechanism is designed for IEEE 802.16e mobile subscriber stations (MSSs) to switch their real-time connections between awake mode and sleep mode. The proposed energy-efficient scheduling algorithm is different from the existing scheduling algorithms in terms of the scheduling priority order and the state transition mechanism for MSSs. The simulation results highlight that with proper scheduling priority and state transition mechanism, scheduling algorithms can effectively improve QoS for IEEE 802.16e networks while achieving high MSS energy efficiency.
