Abstract :
Wireless networks are growing day by day due to the increased demand of using it, so it has become very necessary to improve the quality of service (QoS). The aim of this paper is to study QoS of voice over internet protocol (VOIP) over WiMAX for fixed and mobile WiMAX networks in different power ranges. The basic parameters of QoS which were studied in this paper are the end to end delay , throughput and jitter. Different scenarios were created using computer simulator to evaluate the performance, the study used different numbers of nodes, for three and five cell. The analysis of the results shows that WiMAX networks give a high efficiency using both fixed and mobile nodes for all studied parameters. The influence of transmitter power on the results of end to end delay is approximately not noticed when cells number and mobile nodes increased. The results achieved the required goal of the study.
