Optimal Energy and Data Routing in Networks with Energy Cooperation
Berk Gurakan, Omur Ozel, Sennur Ulukus
We consider the delay minimization problem in an energy harvesting communication network with energy cooperation. In this network, nodes harvest energy from nature for use in data…
Optimal Policies for Wireless Networks with Energy Harvesting Transmitters and Receivers: Effects of Decoding Costs
Ahmed Arafa, Sennur Ulukus
We consider the effects of decoding costs in energy harvesting communication systems. In our setting, receivers, in addition to transmitters, rely solely on energy harvested from n…
Energy Harvesting Transmitters that Heat Up: Throughput Maximization under Temperature Constraints
Omur Ozel, Sennur Ulukus, Pulkit Grover
Motivated by damage due to heating in sensor operation, we consider the throughput optimal offline data scheduling problem in an energy harvesting transmitter such that the resulti…
Secure Degrees of Freedom of Multi-user Networks: One-Time-Pads in the Air via Alignment
Jianwei Xie, Sennur Ulukus
We revisit the recent secure degrees of freedom (s.d.o.f.) results for one-hop multi-user wireless networks by considering three fundamental wireless network structures: Gaussian w…
Secure Degrees of Freedom of One-hop Wireless Networks with No Eavesdropper CSIT
Pritam Mukherjee, Jianwei Xie, Sennur Ulukus
We consider three channel models: the wiretap channel with helpers, the -user multiple access wiretap channel, and the -user interference channel with an external eavesdr…
Secure Degrees of Freedom Region of the Two-User MISO Broadcast Channel with Alternating CSIT
Pritam Mukherjee, Ravi Tandon, Sennur Ulukus
The two user multiple-input single-output (MISO) broadcast channel with confidential messages (BCCM) is studied in which the nature of channel state information at the transmitter…
Energy Harvesting Wireless Communications: A Review of Recent Advances
Sennur Ulukus, Aylin Yener, Elza Erkip +4
This article summarizes recent contributions in the broad area of energy harvesting wireless communications. In particular, we provide the current state of the art for wireless net…
