Dynamic Subcarrier-based Resource Allocation Algorithm in Wireless Networks
This paper proposes a resource allocation algorithm for wireless systems. The algorithm is developed for orthogonal frequency division multiple access (OFDMA) system with frequency hopping and adaptive subcarrier-based assignment. The best subcarriers are assigned to each user by applying multiuser diversity. The proposed two-phase algorithm trades off between system throughput and fairness among users. Data transfer for three users has been simulated in the model. The proposed method shows significant improvement over water filling (WF) and proportional fairness (PF) methods.
