Effect of Power Saving Techniques on the Quality of VoIP

Abstract

Power saving techniques in wireless networks have an effect on the quality of VoIP applications. These techniques are used to reduce the consumption of power when mobile terminals are used for VoIP. This paper will introduce a study on the effect of different techniques (used to reduce power consumption at various layers of the wireless network) on voice quality of service (QoS). The study will concentrate on jitter and delay of voice packets. Current standards for power saving techniques, at each network layers, will be discussed, and their effectiveness will be analyzed. WLAN is used in this study to fully analyze the effect of these power saving techniques on the voice packets jitter and delay. Simulation results are presented to demonstrate the analysis. © 2017, Springer International Publishing Switzerland.
