Opis

This research proposes a quality of service (QoS)§architecture for WiMAX, including a contention period§management algorithm and a price-based scheduling§framework. With a derived probability-based optimal§contention window (P-OCW), we were able to devise a§contention slot allocation algorithm to allocate§contention minislots to flows based on P-OCW. In§addition, a price-based scheduling framework was§developed to provide price differentiation among§users. This scheduling framework was designed to work§using the TDD mode to take advantage of the adaptive§subframe size as well as schedulers of adaptive§price-based deficit round robin (AP-DRR) and§price-based distributed deficit round robin (APDDRR).§From simulation results, we strongly recommend the§use of our contention slot allocation algorithm and§adaptive price-based scheduling framework.
