Abstract

Voice over Internet Protocol (VoIP) communication over Wireless LAN (WLAN) is the fastest growing technology in this era of globalization. This is due to its cost efficiency and its high resource utilization. The latest wireless standard specification endorsed by IEEE is 802.1 ln-2009 has been said that can increase reliability and promotes higher data rates compare to previous standard such as 802.1 lg. However, despite the powerful 802.1 In standard deployment, VoWLAN still imposes drawbacks especially in term of its quality of services (QoS). In this thesis, we will analyze the performance of two speech codec namely G.711 as per ITU-T recommended speech codec and Speex as an open source codec in 802.1 In draft wireless environment. The performance analysis will be focusing on the QoS parameters such as packet jitter, loss, R-factor and MOS Score. The experimental procedure is based on Markov method and divided into three experiments; Experiment 1: Client 1 talks, Client 2 silent; Experiment 2: Client 1 silent, Client 2 talks and Experiment 3: Client 1 and Client 2 talks. After obtaining the result, we will analyze the result and compare it accordingly based on our research objectives that have been outlined in Chapter 1.
