In this paper, we propose an adaptive resource allocation algorithm for multiple traffic orthogonal frequency division multiple access (OFDMA) which distributes the sub-carriers and bit loading among the users according to their different Quality of Service (QoS) requirements and traffic class. From simulation results we can see that our proposed scheme decreases the outage probability for users which requires real-time transmission without impact on the systems spectrum efficiency.
