Fair Resource Allocation in an Uplink OFDMA System

This paper looks at the fairness achievable in an OFDMA system. Based on the results, an online resource allocation algorithm is defined for a reservation-based OFDMA system where the frame duration is much shorter than the duration of a call. Simulations show that the algorithm leads to a considerable reduction in the probability of outage. A protocol is introduced for fair resource allocation between two nodes in an ad hoc system. The minimum required overhead is shown to depend on the level of fairness required, and the bounds that are derived.
