Performance study of Voice in Wireless Mesh Network

The wireless meshed technology is one of the most advanced technology and can be viewed as the technology of the future. This article deals with aspects like performance metrics i.e. delay, R-Factor and Mean Opinion Score (MOS) that have a direct influence on the performance of the wireless mesh network. In this paper voice quality is analyzed in terms of R-Factor and MOS in Wireless Mesh Network by performing simulations using Qualnet. Another issue addressed in this paper is the effect of increasing mesh points on voice transmission in wireless mesh network. The results show that the voice quality matrices R-Factor and MOS degrades and the average delay increases, with increase in number of hops in the Wireless Mesh network.
