Optimizing Adaptive Modulation in Wireless Networks via Utility Maximization
Optimizing Adaptive Modulation Wireless Networks via Utility Maximization
2015/7/9
We investigate adaptive modulation using the network utility maximization framework. We derive new crosslayer optimal power and rate adaptation policies for several practical modulation schemes. The b...

Optimizing Adaptive Modulation Wireless Networks via Multi-Period Network Utility Maximization
2015/7/9
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 al...
We consider the problem of choosing the data flow rate on a wireless link with randomly varying channel gain, to optimally trade off average transmit power and the average utility of the smoothed data...
