UDP Connectivity Performance in VoIP over WiMAX

In the recent years, WiMAX technology is widely used for wireless communication systems in many countries because it has rich set of features with promising broadband wireless access networks. The paper is introducing many cells with the Mobile WiMAX and Fixed WiMAX networksfor better performance over the network protocol UDP. In paper, performance evaluation of WiMAX is done on software opnet. Various real life scenarios have been created to see how different factors such as distance, number of subscriber stations, different modulation schemes and packet size affect the performance of the WiMAX networks. Simulation of performance is carried out for UDP protocol traffic over fixed as well as mobile WiMAX. Throughput, average delay and average jitter are used as performance metrics in this study.
