Quality of Service (QoS) in Wireless Network, VOIP Simulation Environment
A Quality of Service (QoS) is determines if a wireless technology can successfully deliver high value services such as voice and video. The PHY and MAC layers of 802.16 are described in detail with regarding their QoS. The relations and interactions of these QoS mechanisms are described to give an understanding them. The UGS service flow can handles the traffic generated by VOIP calls in the most optimum way. Wireless networking has the potential for use in broadband Internet services, video and audio streaming, and as an alternative to the PSTN for voice service.
