Abstract :
WiMax networks based on Release 1.0 were known for efficient support of data traffic, but were considered inefficient for VoIP capacity, i.e. for supporting a large number of simultaneous VoIP users, due to large control overhead associated with VoIP. Persistent scheduling is a mechanism that was adopted in mobile WiMax Release 1.5 to reduce MAP (control) overhead for VoIP traffic and improve VoIP capacity. This paper presents a performance analysis of persistent scheduling in WiMax. Our simulation results show that persistent scheduling can increase VoIP capacity by 15%.
