چکیده
In order to reduce the power consumption of a mobile station, IEEE802.16e introduced the sleep mode to extend the standby time of battery-powered mobile stations. However, existing mainstream simulation platforms do not yet support the sleep mode. Since simulation tools play increasingly important role in the design, research of network protocols, products and applications, it is of high importance to also have sleep mode support in the popular simulation platforms. This paper describes the design and implementation of a simulation module for sleep mode of IEEE 802.16e mobile WiMAX based on OPNET WiMAX module. Simulations on downlink web business of sleep mode under wireless communications scenario are performed. Simulation results show that the sleep mode can greatly reduce energy consumption of a mobile station while maintaining its quality of service.

A Dynamic Sleep Interval Decision Scheme for Power-Saving with Minimum Delay in IEEE 802.16e Mobile WiMAX
We observe that the state-of-the-art power-saving mechanisms (PSM) for IEEE 802.16e is neither optimal in terms of delay nor in terms of energy consumption. We propose a new PSM which achieves the optimality in terms of the average buffering delay without increasing energy consumption. In order to do so, we derive a formula which relates the average buffering delay to sleep intervals. Simulatio...
