摘要: Voice over IP (VoIP) is a promising low-cost voice communication over the wireless IP network. To provide satisfactory VoIP services, the Quality of Service (QoS) of the wireless network should be guaranteed. This paper proposes a VoIP 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 (c) 2010 John Wiley & Sons, Ltd.
