Executive Summary

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.
