System level evaluation for WiMAX IEEE 802.16m

This paper presents a system level simulator for the evaluation of WiMAX IEEE 802.16m technologies in a multi-cellular environment. This simulator is a quite powerful tool which allows quantifying the benefits of proposed air interface technologies on overall system performance using several metrics. As a case of study, the paper conducts performance evaluation of WiMAX IEEE 802.16m contiguous and distributed sub-channelization modes. The results obtained show a clear advantage for the distributed mode in term of system throughput but not in term of number of simultaneously active users. Similarly, many different cases of study can be further conducted using this simulation platform, which will yield crystal clear conclusions on the performance of WiMAX IEEE 802.16m system.
