IEEE 802.16e, a broadband wireless access technology that provides high speed internet access andmultimedia services has seen very significant growth in recent times. With the due rapid deployment ofWiMAX, there would be a growing demand for efficient support of voice applications. The performanceof Voice over IP services depends on a proper scheduling algorithm combined with a proper Voiceencoder scheme. The contribution of this work is two fold. The first is that we present an efficientscheduling algorithm that can be used for VoIP services in IEEE 802.16e. We then implement thealgorithm in various CODECS and compare the performance of the codec’s i.e.G.728, G.711, G.723,G.729, G.726, GSM-EFR, GSM-HR under similar load conditions for Interactive voice over WiMAX byenabling the Speech Activity Detection (SAD). We analyze the system throughput and delay to evaluatethe performance of our algorithm and the primary metrics that were used in the comparison for choosingthe right vocoders for the algorithm were Jitter, MOS, and packet end to end delay. |
