Intelligent Packet Dropping for Optimal Energy-Delay Tradeoffs in Wireless Downlinks

  title={Intelligent Packet Dropping for Optimal Energy-Delay Tradeoffs in Wireless Downlinks},
  author={Michael J. Neely},
  journal={IEEE Transactions on Automatic Control},
We explore the advantages of intelligently dropping a small fraction of packets that arrive for transmission over a time varying wireless downlink. Without packet dropping, the optimal energy-delay tradeoff conforms to a square root tradeoff law, as shown by Berry and Gallager (2002). We show that intelligently dropping any non-zero fraction of the input rate dramatically changes this relation from a square root tradeoff law to a logarithmic tradeoff law. Further, we demonstrate an innovative… CONTINUE READING
