Abstract:
This project is to study, analyze, plan, design, simulate and evaluate performance of Voice over Internet Protocol through WiMAX network using Opnet software program to detect the acceptable number of nodes which provide less than over packet loss, jitter delay and end to end delay.The object is reduce time delay and data loss and evaluate parameters to achieved good quality of service. Design environment of simulation on Opnet software program and testing each scenario change number of nodes according to packet loss, jitter delay and end to end delay.
