Performance Analysis of QoS Model in Mobile WiMAX System1

In this paper, the QoS(Quality of Service) model in mobile WiMAX system is suggested. For making QoS model in mobile WiMAX system, we have adapted the interworking network model between the mobile WiMAX network and diffserv based on internet. It is confirmed that the QoS level degradation due to handoff events by high speed moving users have effect on the quality of the model in the experimental results. Also, the performance of the suggested model by three experimental metrics is analyzed and estimated.
