摘要：The Worldwide Interoperability for Microwave Access (WiMAX) is a set of technical standards based on IEEE802.16 standard, WiMAX is an alternative solution for the deployment of broadband networks in the territories, whether or not covered by other technologies such as ADSL or cable In this paper the performance of various QPSK and QAM modulation techniques by applying the many mobility patterns sch as static, random, and trajectory for Video on Demand (VoD) over WiMAX Network. The work is done in terms of the traffic sent, throughput and traffic received by using OPNET simulator 14.5. Simulation result indicates that when nodes are moving by SVC codec scheme in WiMAX, the best result is obtained and total performance of QPSK modulation technique is better as compared to QAM modulation.
