The emerging IEEE 802.16m standard provides a new sleep mode operation for Mobile Stations (MSs). It evolves from the sleep mode operation in the IEEE 802.16 standard but with more advanced features, e.g., the listening window may be extended and the sleep cycle length is adjustable. To fully exploit these advancements, we conduct a comprehensive analytical study on the power consumption and average packet delay under the new sleep mode operation. Then, based on the analytical results, we propose a novel adaptive sleep mode management scheme called Adaptive Sleep Mode Management (ASMM), which adjusts an MS's sleep cycle and listening window in an adaptive manner based on online monitoring and estimation of the traffic condition. The goal is to minimize the power con- sumption by the MS while limiting the average packet delay under a user-specified level. The effectiveness of ASMM is demonstrated via simulation-based performance evaluation. 2011 Elsevier B.V. All rights reserved.

    ABSTRACT: Power saving mechanisms with sleep-mode operations have been used in IEEE 802.16e in order to extend the battery lifetime of mobile devices. The standard sleep-mode operation needs to meet a given delay constraint. However, it may incur unnecessary energy consumption due to frequent state transitions. In this paper, we propose a new energy-efficient sleep-mode operation while meeting a given delay requirement. We apply an M/G/1 queue model with multiple vacations for downlink traffic in an error-free environment in order to evaluate the energy efficiency performance of the proposed sleep-mode operation in terms of packets/Joule. We compare the proposed sleep-mode operation with the standard sleep-mode operation. The results show that our proposed sleep-mode operation improves the total energy efficiency consumption per unit frame time by 35% and energy efficiency by 21% while meeting a given delay requirement.

    ABSTRACT: So far, many studies have been made for the 802.16m sleep mode operations. However, in the previous work, the equation derivations are too complicated to be used or analytical models are not accurate. We introduce an accurate analytical model through simple derivations in case when a sleep cycle is constant assuming M/G/1 queuing model.
