Voice over Internet Protocol (VoIP) is a transmission technology that allows voice to be delivered over the Internet with support of Internet Protocol. Recently, the integration of VoIP and Wireless Local Area Network (WLAN) has become popular, driven by mobility requirements of the users. However, WLAN architecture was primarily designed to carry data and not for voice. Hence, there is a need to...
Multi-homed Mobile nodes (MNs) are very likely to traverse several different WLANs at anytime and at any location during communication. Thus, a single voice over Internet protocol (VoIP) application can experience several handovers between WLANs, which the quality of the communication may be degraded due to packet loss. The handover scheme proposed in this paper employs the delay over WLAN as an indicator...
The deployment of wireless mesh paradigm was meant to extend Internet access without a consideration of delay sensitive applications. None the less, since voice over IP (VoIP) services are rapidly increasing in popularity, IEEE 802.11 based wireless mesh networks are challenged with the provision of guaranteed quality VoIP calls. In this paper, the disquiet on VoIP systems caused by physical (PHY)...
