This paper proposes a scheme for the distributed power saving mechanism of IEEE 802.11e networks in consideration of the Quality of Service requirement. In the proposed protocol, each station enters into sleep-mode and active-mode periodically according to the appropriate trigger interval. For obtaining the appropriate trigger interval, this paper presents the objective function of power consumption in consideration of the acceptable delay required by each access category. Each station optimizes its trigger interval according to the objective function. Simulation results show the effectiveness of the proposed scheme.
