Improving IEEE 802.11 power saving mechanism
This paper presents a mechanism that improves the energy efficiency of PSM (Power Saving Mechanism) specified for DCF (Distributed Coordination Function) in IEEE 802.11. In PSM, time is divided into beacon intervals. At the start of each beacon interval, every node stays awake for a duration, called the ATIM Window. During the ATIM window, nodes exchange control packets to determine whether the...
متن کاملAn Effective Power Saving Mechanism for IEEE 802.11 PSM in Double-layered Mobile P2P Systems
In this paper, we propose a scheme for double-layered mobile P2P systems that enhances energy efficiency by modifying PSM(Power Saving Mode) defined in 802.11. The proposed scheme lengthens the beacon interval adaptively and adopts a known power saving scheme for more power saving. The experimental results showed that the proposed scheme improved 58.3% in terms of the average energy saving and ...
متن کاملModeling and Simulation of Power Saving Mechanism for IEEE 802.16e Mobile WiMAX
In order to reduce the power consumption of a mobile station, IEEE802.16e introduced the sleep mode to extend the standby time of battery-powered mobile stations. However, existing mainstream simulation platforms do not yet support the sleep mode. Since simulation tools play increasingly important role in the design, research of network protocols, products and applications, it is of high import...
متن کاملEnhanced Power Saving Mechanism to Maximize Unavailability Interval in the IEEE 802.16 Mobile WiMAX
In this paper, an energy conservation mechanism to maximize the unavailability interval and to improve the energy efficiency for the Power Saving Class in WiMAX are proposed. The proposed method can be implemented in commercial fields and is fully compatible with the 802.16 standard. It provides a systematic way to adjust the start frame number of the first sleep window, one of the relevant par...
متن کاملPower-saving mechanism with delay bound for Mobile WiMAX systems
In Mobile WiMAX, the power saving mechanism (PSM), which operates alternately in sleep and awake modes, works to extend the lifetime of mobile stations (MSs), though it concurrently induces a medium access control (MAC) service data unit (SDU) response delay. In this paper, we derive the analytical models for two of the most important performance metrics: the average power consumption and the a...
