FAIRNESS FOR OPTIMIZATION IN COOPERATIVE WIRELESS CELLULAR NETWORKS
Cooperative communication can improve the performance of cellular mobile networks. The optimization techniques based on duality theory, decomposition and subgradient method were applied for such wireless cellular cooperative systems. It was shown that the joint optimization and resource allocation problem can be solved efficiently within a network utility maximization framework. A concept of proportional fairness was used to achieve fair distribution of quality of service among users. Simulation results confirm the validity of the theoretical work.
