To overcome the flaw of energy efficiency drop in broad band wireless communication with the short time sleep, the energy-saving mechanism of the sleep mode operation was researched in IEEE 802.16e. In this paper we propose a dynamic algorithm to tune the ratio of the sleep windows and receive windows according to the traffic load. Then, a Markov chain model was set up to analyze the energy efficiency...
To enhance the energy efficiency of broadband wireless access devices based on battery power, a traffic-aware based adaptive sleep mode operation was proposed for IEEE 802.16e power saving mechanism. By analyzing the behaviors of a mobile station working in the sleep mode operation with a Markov chain model, we explore the relationship among traffic, energy consumption and delay. Based on the analytical...
To enhance power efficiency of battery powered wireless access devices, the behaviors of the mobile stations (MS) working in the sleep mode operation in IEEE 802.16e was researched with a method of the Markov chain model. By exploring the relationship among traffic load, power consumption and delay, we present a cross-layer design-based algorithm to tune the initial sleep window according to the randomization...
In this paper, we propose a dynamic traffic load-aware sleep mode operation to improve the power efficiency of battery powered IEEE 802.16e devices. By analyzing the sleep mode operation with a Markov chain model, we explore the relationship among traffic load, power consumption and idle check time. Based on the analytical results, we propose a dynamic algorithm to tune the idle check time according...
