Power saving is one of the most important issues in mobile wireless broadband access system. The IEEE 802.16e standard proposes an energy saving mechanism that named ``sleep mode" for conserving the power of the mobile stations. To model the operating mechanism of the sleep mode for downlink traffic in the type I power saving class, a discrete-time Geom/G/1 queueing model with a close-down time and multiple vacations is
built. Using an embedded Markov chain method and Little's law, we analyze the queueing model and get the performance measures of the energy saving rate and the mean packet delay time for the sleep mode in the IEEE 802.16e. Finally, numerical results are given to demonstrate the dependency relationships between the system performance measures and the system parameters and a cost model is developed to determine the optimum length of the close-down time. |
