NCTU-VT: a freeware for wireless VoIP performance measurement
نویسندگان
چکیده
Voice over IP (VoIP) is a promising low-cost voice communication over thewireless IP network. To provide satisfactoryVoIP services, theQuality of Service (QoS) of thewireless network should be guaranteed. This paper proposes aVoIP performance measurement freeware called NCTU VoIP Testing Tool (NCTU-VT). We compare NCTU-VT with two commercial tools SmartVoIPQoS and IxChariot in terms of packet loss, latency, and Mean Opinion Score (MOS) of the VoIP sessions in Wi-Fi network. Our study indicates that these three tools can accurately measure VoIP performance in Wi-Fi environment. Copyright © 2010 John Wiley & Sons, Ltd.

A client-side design and implementation for push to talk over cellular service
This paper proposes a client architecture for the Push to Talk over Cellular (PoC) service based on the Open Mobile Alliance (OMA) PoC specifications v1.0 release. We show that most standard VoIP modules can be reused for the PoC client, and the VoIP software can be easily extended to support PoC service. Then we present the detailed message flows between the PoC client and other network entiti...

متن کاملPerformance Study of Objective Speech Quality Measurement for Modern Wireless-VoIP Communications
Wireless-VoIP communications introduce perceptual degradations that are not present with traditional VoIP communications. This paper investigates the effects of such degradations on the performance of three state-of-the-art standard objective quality measurement algorithms—PESQ, P.563, and an “extended” E-model. The comparative study suggests that measurement performance is significantly affect...
