In IEEE Standards 802.16e (air interface standard for MWiMAX) and 802.16m (evolution of MWiMAX for IMT-Advanced), power saving is one of the important issues for battery-powered mobile stations (MSs) due to mobility. According to the IEEE 802.16e standard, when an MS switches from awake mode to sleep mode, the MS is required to send a sleep request (MOB-SLP-REQ) message and to receive a sleep response...
The IEEE 802.16e mobile WiMAX technology aims to provide with an energy efficient communication platform for various mobile applications. In the standard, the sleep mode feature with three Power Saving Classes (PSCs) is designed to compensate for the power saving as the target. Prior work has shown that the proposed Markov Decision Process (MDP) approach can achieve the optimal performance in terms...
Sleep mode is a key feature introduced in IEEE 802.16e standard, which ensures power-efficient operation of battery operated mobile devices. The 802.16e standard does not define when to take decision to trigger sleep mode. However to the best of our knowledge some published works define waiting time threshold as a time for which mobile subscriber station (MSS) waits before entering into sleep mode,...
