Can we reduce Wi-Fi energy consumption during VoIP calls?

Published: 10 December 2007 Publication History

Abstract

In this paper we examine if any energy savings are possible by letting the Wireless LAN interface transition to sleep mode during a VoIP call considering the real time nature of voice. Using our proposed energy saving algorithm Green-Call, we show that it is possible, and quantify the possible savings through both empirical and trace based simulation experiments.
