Perceived voice quality is mainly affected by IP network impairments such as delay, jitter and packet loss. Adaptive smoothing buffer at the receiving end can compensate for the effects of jitter based on a tradeoff between delay and loss to archive a best voice quality. This work formulates an online loss model which incorporates buffer sizes and applies the ITU-T E-model approach to optimize ...

Time, day, location and instantaneous network conditions largely dictate the quality of Voice over IP calls. In this paper we present results of VoIP quality mainly in terms of packet jitter and loss. This work revisits our objective of measuring VoIP quality in 1999 enabling us to make comparisons with the results we obtained three years ago. It also allows us to improve the measurement infra-...

This paper reviews existing power management techniques on wireless LAN and verifies the effects of different power management techniques applied to the case for VoIP over WiFi through experiments. Voice communication imposes timely constraints such as short time interval between packets and the need to be always listening for potential incoming connections. It also poses opportunities related ...

Abstract This article is based on an interview study of workers in Sweden’s healthcare and educational sectors who raise or withhold concerns about conditions at the workplace.
