Multi-Level Queue based Resource Allocation in Downlink of OFDMA Wireless Cellular Networks

Objectives: Optimizing the resource allocation to improve throughput in the downlink of OFDMA based wireless cellular networks. Method/Statistical Analysis: In the proposed method, a multi-level queue based resource allocation is proposed where different classes of users will be assigned different queues and different algorithms can be applied to them. The algorithm is implemented and its performance is analyzed and the results are collected and compared with the existing solutions to evaluate the algorithm behavior under different channel conditions. Findings: The algorithm improves the performance and ensures the fairness among the various classes of users based upon the chosen parameters. Also, the algorithm can be configured to either improve the throughput or ensure the fairness depending on the requirements. Applications/Improvement: The algorithm improves the performance and provides a way for different classes of users to be assigned different priorities.
