Ensuring confidentiality of communication is fundamental to securing the operation of a wireless system, where eavesdropping is easily facilitated by the broadcast nature of the wireless medium. By applying distributed beamforming among a coalition, we show that a new approach for assuring physical layer secrecy, without requiring any knowledge about the eavesdropper or injecting any additional cover noise, is possible if the transmitters frequently perturb their phases around the proper…

The feasibility of using distributed antenna systems to facilitate the deployment of IoT devices is discussed and the preliminary results demonstrate that this energy ball has a great potential to be leveraged to solve many fundamental problems in IoT and enable exciting IoT applications.

Towards flexible wireless charging for medical implants using distributed antenna system

In-N-Out can continuously charge a medical implant residing in deep tissues at near-optimal beamforming power, even when the implant moves around inside the human body, and is sufficient to wirelessly power a range of commercial medical devices.

Pushing the Range Limits of Commercial Passive RFIDs

PushID is presented, a system that exploits collaboration between readers to enhance the range of commercial passive RFID tags, without altering the tags whatsoever, and resolves the chicken-or-egg problem of inferring the optimal beamforming parameters to beam energy to a tag without any feedback from the tag itself.

Energy-Ball

This paper presents a new power transfer approach by aligning the phases of a collection of radio frequency energy chargers at the target receiver device, referred to as Energy-Ball, which can ship energy over tens of meters and to mobile targets.

Enabling Concurrent IoT Transmissions in Distributed C-RAN

A distributed C-RAN is built which has tens of distributed radio frontends using USRP N210s in a 20 × 20 × 3 m3 area and can potentially decode collided signals from low-end IoT devices with all signal processing been done on the cloud.

QoS-Based Transmit Beamforming in the Presence of Eavesdroppers: An Optimized Artificial-Noise-Aided Approach

This paper proposes a secret transmit beamforming approach using a quality-of-service (QoS)-based perspective, and proves that SDR can exactly solve the design problems for a practically representative class of problem instances; e.g., when the intended receiver's instantaneous CSI is known.

This paper considers the problem of secret communication between two nodes, over a fading wireless medium, in the presence of a passive eavesdropper, and assumes that the transmitter and its helpers (amplifying relays) have more antennas than the eavesdroppers.

Improving Wireless Physical Layer Security via Cooperating Relays

Novel system designs are proposed, consisting of the determination of relay weights and the allocation of transmit power, that maximize the achievable secrecy rate subject to a transmit power constraint, or minimize the transmit powersubject to a secrecy rate constraint.

The utility of user cooperation in facilitating secure wireless communications is established and an outer-bound on the optimal rate-equivocation region is derived and the novel noise-forwarding strategy is used to illustrate the deaf helper phenomenon.

Secrecy Wireless Information and Power Transfer With MISO Beamforming

This paper addresses the new physical-layer security problem in a multiuser multiple-input single-output (MISO) SWIPT system where one multi-antenna transmitter sends information and energy simultaneously to an IR and multiple ERs, each with one single antenna.
