摘要

Most of the Future Internet users will be wirelessly connected to IP clouds through different types of wireless networks. Thus, the number of applications and devices will be increased, and IPv6 insists to be applied. Voice over IP (VoIP) is one of the most popular Internet applications which provide real time voice communications between different parties and network systems. The Quality of Service (QoS) for VoIP influenced by the performance metrics which are signaling, bandwidth, packet loss, delay, and jitter. The signaling is the main parameter that manages and controls VoIP calls. One of the most efficient signaling systems for VoIP is the Session Initiation Protocol (SIP). MANETs consist of changeable bandwidth with considerable delays which affects the VoIP QoS. The first stage of my PhD research is to evaluate the performance metrics of the SIP based VoIP applications over IPv6 MANET using OPNET modeler with different voice Codecs and Mobility Models. The evaluation results showed considerable differences in the performance of the real-time applications between different MANET routing protocols. In conclusion, SIP acts poorly in IPv6, and both SIP signaling and IPv6 need to be enhanced for real time applications over MANET.
