Abstract:

To satisfy different service requirements of multiple users in the orthogonal frequency division multiple access wireless local area network(OFDMA-WLAN)system downlink transmission, a resource allocation algorithm based on fairness and quality of service(QoS)provisioning is proposed. Different QoS requirements are converted into different rate requirements to calculate the QoS satisfaction level. The optimization object is revised as a fairness-driven resource optimization function to provide fairness. The complex resource allocation problem is divided into channel allocation and power assignment sub-problems. The sub-problems are solved by the bipartite graph matching and water-filling based method. Compared with other algorithms, the proposed algorithm sacrifices less data rate for higher fairness and QoS satisfaction. The simulation results show that the proposed algorithm is capable of providing QoS and fairness, and performs better in a tradeoff among QoS, fairness and data rate.
