Voice over IP (VoIP) applications such as Skype, Google Talk, and FaceTime are promising technologies for providing cheaper voice calls to end users over extant networks. ireless networks such as WiMAX and Wi-Fi focus on providing perfection of service for VoIP. However, there are numerous aspects that affect quality of voice connections over wireless networks [13]. The adoption of Voice over Wireless Local Area Network is on tremendous increase due its relief, non-invasive, economicexpansion, low maintenance cost, universal coverage and basic roaming capabilities. However, expansion Voice over Internet Protocol (VoIP) over Wireless Local Area Network (WLAN) is a challenging task for many network specialist and engineers. Voice codec is one of the most critical components of a VoIP system. In this project, we evaluate the performance analysis of various codecs such as G.711, G.723 and G.729 over Wi-Fi networks. NS2 WiFi simulation models are designed. Performance metrics such as Mean Opinion Score (MOS), average end-to-end latency, and disconcert are evaluated and discussed [13]. 1. In this paper, our area of interest is to compare and study the performance analysis of VoIP codecs in Non-mobility scenarios by changing some parameters and plotting the graphs throughput, End to end Delay, MOS, Packet delivery Ratio, and Jitter by using Network Simulator version. 2. In this paper we analyze the different performance parameters, Recent research has focused on simulation studies with non- mobility scenarios to analyze different VoIP codecs with nodes up to 5. We have simulated the different VoIP codecs in non-mobility scenario with nodes up to 300.
