With the IEEE 802.16e standard for Mobile WiMAX the course for new 4G mobile radio communication systems is set. It offers significantly higher data rates than GSM or WCDMA/UMTS and supports different handover mechanisms and QoS features in contrast to WiFi (IEEE 802.11g) on the OSI-layer 2 (L2). Since WiMAX-devices are hardly available today and protocol optimizations are strongly restricted with commercially available devices, a simulation model is not far to seek. Thus, the authors developed and implemented a simulation in OMNeT++ based on the INET framework in order to investigate and evaluate the performance of the new Mobile WiMAX protocol.
