QOS aware resource allocation for heterogeneous multiuser OFDM wireless networks

Abstract

We consider a heterogeneous multiuser OFDM wireless network serving both QoS constrained high-priority users and best-effort users. We investigate resource allocation to maximize the total network utility by specifying two different utility functions for the two user classes. Our strategy is to first maximize the number of satisfied high-priority users before allocating the remaining resource among the best-effort users. Our results show significant improvement of overall user satisfaction among both user classes.
