Integrated Power-Saving Scheduling for IEEE 802.16e Networks

Abstract

The mobility of IEEE 802.16e introduces an important issue for battery-powered mobile station to extend the operational lifetime. Although the sleep-mode operation in power management helps to increase the life of mobile station by saving energy consumed, since the sleep-mode operation is not fully integrated with the scheduling mechanism, the energy-saving efficiency is not utilized due to the reciprocal effect between the connections. In order to effectively use the channel bandwidth and provide energy efficiency for wireless mobile station, this research developed a scheduling method, in attempt to provide energy saving based on the premise of different service delayed restrictions.
