Performance Evaluation of Qos in WiMAX Network

Quality of Service is an essential parameter to judge performance of any Network. Our paper focuses on analyzing essential QoS parameters for Wimax Network. Essential QoS parameters like delay, Jitter, Packet delivery Ratio (PLR), Packet Loss Ratio (PLR) and throughput have been calculated for 500 mobile nodes in a WiMax network. The worldwide interoperability for microwave access (WiMAX) is one of the newest technologies developed for broadband wireless network which offers high data rates, long coverage area and several types of quality of services to the users. The results are helpful in analyzing QoS parameters for WiMax Network and it has been found that an optimum value of QoS parameters is obtained with increasing number of mobile nodes for WiMax Network.. It is concluded that our models shorten the time quite a bit for obtaining the performance measures of an end-to-end delay as well as throughput can be used as an effective tool for this purpose.
