Title
Weighted Network Utility Maximization Aided By Combined Queuing Priority In Ofdma Systems
Abstract
Network Utility Maximization (NUM) is an effective tool in cross layer design. This paper extends the traditional NUM into a more general framework of Weighted Network Utility Maximization (WNUM) and studies the multi user resource allocation problem in Orthogonal Frequency Division Multiple Access (OFDMA) networks. Combined Queuing Priority is introduced to serve as a tool which helps to configure the weight parameters. Mathematical solutions to WNUM with various constrain sets in OFDMA systems are also provided. The presented WNUM optimization helps to reduce the complexity in cross layer design and is capable of making trade offs, between efficiency and fairness. Numerical results show that the WNUM scheme can outperform Throughput-Optimal scheme in both average queue length and average delay time.
