Integrated Load-Based Power Saving for BS and MSS in the IEEE 802.16e Network
In the authors' previous paper, the limitation of standard type I and II power saving in IEEE 802.16e was discussed and the idea of Load-Based Power Saving (LBPS) was proposed. LBPS measures traffic load and adaptively generates proper sleep schedule for the current load. Three LBPS schemes has been proposed for MSS (Mobile Subscriber Station) power saving. In this paper, BS power saving is taken into consideration, and their previously proposed LBPS schemes are revised in order to integrate both BS (Base Station) and MSS in sleep scheduling.
