Study of data scheduling methods in the WiMAX mobile metropolitan wireless networks

The paper discusses basic assumptions of the WiMAX Mobile system. It also presents and analyses the results of simulation tests run for selected data scheduling methods and subcarrier allocation. Based on the test results, the authors have prepared a comparative analysis of two popular data scheduling methods, i.e. WRR and PF, and their own method CDFQ which uses information about the current channel situation for the queuing processes and data allocation. The tests have been conducted with a simulator designed by the authors, based on work defined quality criteria.
