Performance analysis of QoS for WiMAX using OPNET

In this paper, the performance of quality of services for an IEEE 802.16 based WiMAX access network is analyzed. WiMAX is an emerging broadband wireless communication standard used as a mode of transmission and high speed internet access. WiMAX is a technology which provides more bandwidth, better QoS, better security, greater coverage and has low infrastructure cost. The quality of service related parameters i.e jitter, throughput etc. are evaluated in this study using opnet modeler 14.5. QoS is collective effectiveness of the service as perceived by the user. The simulation results provided in the paper gives a better choice of WiMAX´s service classes and these are investigated in the terms of various QoS related metrics.
