For the battery-powered wireless stations, power saving is one of
the significant issues in IEEE 802.11 wireless local area network
(WLAN). Recently, Lei and Nilsson investigated the power save mode
in IEEE 802.11 infrastructure mode by an M/G/1 queue with bulk
service. They obtained the average packet delay and lower and upper
bounds of the average Percentage of Time a station stays in the Doze
state (PTD). In this paper, the further investigation of power save
mode is done; simple derivation of the average and the variance of
packet delay and the exact value of PTD are obtained. Numerical
results show that our analytic results for PTD match quite well with
simulation results. Using our performance analysis, we can find the
maximal listen interval which minimizes the power consumption of a
station while satisfying the required quality of service (QoS) on
the average and the variance of packet delay.
