BPF and MPF-based packet scheduling for AMC-based OFDMA wireless communication systems

Abstract

Two novel packet scheduling algorithms, the basic and modified priority and fairness (BPF and MPF)-based packet scheduling algorithms, are proposed in this paper for adaptive modulation and coding (AMC)-based orthogonal frequency division multiple access (OFDMA) systems. In the proposed algorithms, various user traffics are transmitted in a sequence determined by their priorities on subchannels while jointly considering fairness among users and subchannels. Simulation results show that the proposed algorithms increase the number of supported users satisfying the same underlying quality of service (QoS) requirements than some existing packet scheduling algorithms in literature.
