2009 Fourth International Conference on Communications and …, 2009•ieeexplore.ieee.orgIEEE 802.16 based WiMAX is fast emerging as a representative last-mile broadband
wireless access technology. In this paper, a novel uplink performance analysis model
focusing on the VoIP services in TDD-OFDMA based WiMAX network is proposed. Based on
the analysis model, the effect of scheduling and resource allocation on the VoIP
performance is discussed. The numerical results show that the packet aggregation in MAC
layer and a reasonable polling interval both can improve the VoIP capacity in WiMAX …
