Simulative Investigation of QoS parameters for VoIP over WiMAX networks
WiMAX is a wireless broadband access technology which provides high data rates, long coverage and IP based connectivity to the stationary as well as mobile users. Voice over Internet Protocol (VoIP) through WiMAX is found to be very promising. In this paper, simulative investigations have been done to identify the suitable voice codec for the same. In doing so, silence suppressed voice signal are also used. Investigations have been done in terms of Quality of Service parameters like jitter, packet end to end delay and Mean Opinion Score. Extensive simulations have been done to shortlist the suitable audio codec for VoIP over WiMAX.
Keywords: WiMAX, VoIP, OPNET, QoS, voice codec.
