Interference-Aware Energy-Efficient Power Optimization

Since battery technology has not kept up with the demand for battery capacity on mobile devices, power optimization techniques are becoming increasingly important in wireless system design. Power optimization schemes are critical to interference management in wireless systems as interference usually results from aggressive spectral reuse and high power transmission and severely limits system performance. In this paper, the authors develop energy-efficient power optimization schemes for interference-limited communications. They consider both circuit and transmit powers and focus on energy efficiency over throughput. Because power optimization problem in the presence of interference is intractable, they first study a simple two-user network with ideal user cooperation and then develop a non-cooperative game for energy-efficient power optimization.
