Voice over Internet Protocol (VOIP) is one of the most notable applications of internet. Some other well known terms used for VOIP in literature include IP telephony or Internet telephony. It can be a better replacement for the traditional telephone systems because of its high resource utilization as well as low cost. Beside this, wireless LAN Network (WLAN) has emerged as a robust networking technology. Hence, the combination of these two popular technologies is growing so fast all over the world. Voice over WLAN (VoWLAN) will be an infrastructure to provide low-cost wireless voice services. However, similar to other wireless applications, VoWLAN has also faced numerous challenges that need to be considered. Quality of Service (QoS) is one of the essential challenges in all kind of wireless applications. In this study, we have critically reviewed the most important QoS requirement; the challenges imposed by these applications as well as some of the QoS enhancement methods.
