Abstract
A power management scheme for use in a wireless device reduces the power consumption of the network interface module of the wireless device by selectively putting the network interface module into a low-power state for an idle time. The length of the idle time is calculated such that the amount of delayed traffic data accumulated is expected to be less than or equal to a pre-selected threshold when the network interface module is put in the low-power state for the calculated idle time. The amount of delayed traffic data as a function of the idle time is modeled using average inter-arrival and service rates that are derived from traffic statistics data.
