RF Energy Harvesting in Wireless Networks with HARQ [PDF]
2016 IEEE Globecom Workshops (GC Wkshps), 2016 In this paper, we consider a class of wireless powered communication networks using data link layer hybrid automatic repeat request (HARQ) protocol to ensure reliable communications. In particular, we analyze the trade-off between accumulating mutual information and accumulating RF energy at the receiver of a point-to-point link using HARQ with ...

Harvesting or scavenging the RF(Radio Frequency) energy, better known by its engineering name — “RF energy Scavenging”, is one of the emerging fields, with very good research opportunities. It is a technique, by which, we utilize the RF energy present in the external atmosphere, by scavenging, and convert it into an useful electrical output for driving

Rectenna for RF energy harvesting
2016 International Conference on Advances in Electrical, Electronic and Systems Engineering (ICAEES), 2016This paper presents the design of rectenna for RF energy harvesting system. The resonance frequency of the different parts of the rectenna such as the antenna and rectifier circuit is 2.45 GHz. The Microstrip patch antenna was designed using commercially available CST software. The patch antenna was then fabricated and tested using Network Analyzer. In

IEEE Transactions on Microwave Theory and Techniques, 2014
This paper discusses harvesting of low-power density incident plane waves for electronic devices in environments where it is difficult or impossible to change batteries and where the exact locations of the energy sources are not known. As the incident power densities vary over time and space, distributed arrays of antennas with optimized power ...

Device-Selective Energy Request in RF Energy-Harvesting Networks
IEEE Communications Letters, 2021In a Wireless Local Area Network (WLAN), devices have limited battery capacity. To improve the energy efficiency, we propose a new Medium Access Control (MAC) protocol to perform selective energy transfer request based on the amount of residual energy of a device in a WLAN with IEEE 802.11 Distributed Coordination Function (DCF).

Electronic devices have different power requirements. The devices which operate continuously require continuous power supply. Some devices operate periodically such as WSN node, which are powered on for particular time and remains in sleep mode otherwise. These nodes require power in $\pmb{\mu} \mathbf{W}$ to $\mathbf{mW}$ , The power density of the
