| Abstract | ||||
| In this paper some WiMAX MAC layer parameters will be optimized to improve applications performance. The study is aimed to show, via simulation, the effect of Automatic Repeat Request (ARQ) parameters on the WiMAX performance. Also, it is aimed to verify the effectiveness of Unsolicited Grant Service (UGS), Real Time Polling Service (rtPS), and Enhanced Real Time Polling Service (ertPS) in managing voice traffic and their effect on data traffic which use Best Effort (BE) service. The results show that the video delay will be increased by from 5 ms to 24 ms when enabling ARQ protocol on WiMAX network. It also give the optimum parameters for ARQ protocol to improve the WiMAX network performance. The research also shows that the best scheduling service for voice is UGS; but it reduces the throughput for BE data. | ||||
