Optimal Packet Scheduling in an Energy Harvesting Communication System
  • Jing Yang, S. Ulukus
  • Computer Science, Mathematics
  • IEEE Transactions on Communications
  • 6 October 2010
We develop optimal off-line scheduling policies which minimize the time by which all packets are delivered to the destination, under causality constraints on both data and energy arrivals. Expand

Transmission with Energy Harvesting Nodes in Fading Wireless Channels: Optimal Policies
We consider optimization of point-to-point data transmission with an energy harvesting transmitter which has a limited battery capacity, communicating in a wireless fading channel. Expand

Achieving AWGN Capacity Under Stochastic Energy Harvesting
We show that the information-theoretic capacity of the AWGN channel with such stochastic channel input constraints is equal to the capacity with an average power constraintequal to the average recharge rate. Expand

  • Computer Science, Mathematics
  • IEEE Trans. Inf. Theory
  • 24 September 2012
We study the secure degrees of freedom (d.o.f.) of one-hop wireless networks by considering four fundamental wireless network structures: 1) Gaussian wiretap channel; 2) gaussian broadcast channel with confidential messages; 3)Gaussian interference channel with confidentiality messages; 4) Gaussie multiple access wiretap channels.
