Performance Evaluation of IMS Multimedia Over WiMAX
Source: University of Cape Town
Telecommunication networks have evolved steadily to meet the ever increasing demand of users. Hence, the Internet Protocol Multimedia Subsystem (IMS) will make it possible to provide ubiquitous computing to the end-user. WiMAX is based on the IEEE 802.16 standard engineered to provide wireless broadband access, but the main focus of this paper, is the use of fixed WiMAX as a backhaul for VoIP and IPTV. A performance evaluation of VoIP and IPTV quality of service was done over the WiMAX network. The authors examined the performance of these services over various codecs, analyzing the key performance metrics such as delay, latency, jitter and packet loss. With respect to VoIP sessions, the quality of the service was measured using the ITU-T E Model.
