The authors contribute to the spectrum of quality of experience (QoE) research by defining simulation platform for evaluation of VoIP quality of experience over a wireless WiMAX link. In particular the authors show how the Matlab/Simulink and ns2 integration can be facilitated to tackle the QoE aspects in a comprehensive manner. Furthermore the process of measuring QoE using an off-line implementation...
Although by default the Network Simulator 2 (NS2) does not implement the IEEE 802.16 networks, a few patches are available, that provide WiMAX specifications at different fidelity level. The ns2 environment is useful for system-level evaluation, but mainly with respect to wired networks. In order to provide an adequate QoS provisioning to different service flows and to prevent base station (BS) from...
WiMAX (worldwide interoperability for microwave access) based upon the IEEE 802.16 standards is a promising technology for the ??last mile?? wireless Internet access. In order to provide required QoS level to different service flows and to prevent base station (BS) from running out of resources dedicated connection admission control (CAC) algorithm has to be implemented. Since the introduction of...
