TCP-aware power control in wireless networks

Hui Zang, Majid Ghaderi, Ashwin Sridharan
2009 2009 17th IEEE International Conference on Network Protocols  
Modern cellular networks commonly deploy rapid channel rate adaptation to vary the wireless capacity in response to channel conditions while maintaining a fixed target error rate (typically 1%).  ...  In this work, we show that elastic traffic, in particular TCP, benefits greatly from the perspective of power efficiency when we also incorporate target error rate adaptation.  ...  Our contributions can be summarized as follows: 1) We propose a TCP-aware power control mechanism that exploits the presence of large buffers in wireless networks to improve power efficiency. 2) We develop  ...
