IEEE 802.16e is the latest broadband wireless access standard
designed to support mobility. In mobile networks, how to control
energy consumption is one of the most important issues for the
battery-powered mobile stations. The standard proposes an energy
saving mechanism that named "sleep mode" for conserving the power
of the mobile stations. According to the operation mechanism of
the sleep mode for downlink traffic in the type I power saving
class, a discrete-time Geom/G/1 queueing model with close-down
time and multiple vacations is built. By employing an embedded
Markov chain method and Little's law, the average queue length,
the average sojourn time and the average busy cycle of the
queueing model are derived. Correspondingly, we get the
performance measures of the energy saving rate and the average
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. Furthermore, a cost model is developed to
determine the optimum length of the close-down time for minimizing
the total system cost.
