Optimizing Adaptive Modulation in Wireless Networks via Multi-Period Network Utility Maximization

  title={Optimizing Adaptive Modulation in Wireless Networks via Multi-Period Network Utility Maximization},
  author={Daniel O'Neill and Ekine Akuiyibo and Stephen P. Boyd and Andrea J. Goldsmith},
  journal={2010 IEEE International Conference on Communications},
We present a crosslayer technique to find and characterize optimal control policies for wireless networks operating at different time scales at the upper layer and physical layer. The technique can also be directly applied to networks carrying traffic with different time dependencies such as data or video. Our approach combines network utility maximization and adaptive modulation over an infinite discrete time horizon using a class of performance measures we call time smoothed utility functions… CONTINUE READING
