“…The model considered by authors in [30] and [31] aim to maximize the overall SNR of the CC system by proposing an adaptive power splitting protocol. To enhance the harvested energy, authors in [32] have also proposed a dynamic power split receiver and proposed moving the Information Decoding load to a different circuitry. However, the above cited works mostly considers a system with a dynamic WPS.…”

Next generation wireless systems include battery operated devices which demand higher throughput and a better reliability in an energy efficient fashion. To fulfil these requirements, In this paper, we propose a novel scenario where we include a dynamic Wireless Power Splitting (WPS) factor for Energy Harvesting (EH) at nodes in a Drone Assisted Network Coded Cooperation (DA-NCC) system. The dynamic WPS factor used for EH in DA-NCC system is made more realistic by determining through the probability of Line-of-Sight (LoS) occurrence. Analytical framework is developed for residual Analog Network Coding (ANC) noise and variance of ANC-noise in EH scenario. We also derive the average rate and average outage probability expressions for the proposed channel model. Various algorithms are developed for deciding the Air-to-Ground (A2G) channel distributions, harvesting the energy at relay and source nodes and evaluating the performance metrics of our proposed work. Our investigations reveal that the use of EH in DA-NCC improves the lifespan of the network. Our findings play important roles in disaster management scenarios where cellular connections to base stations are disrupted due to natural calamities and battery constrained drones are deployed for assistance.

“…Energy harvesting (EH) is a process defined by the capture and conversion of ambient energy like sound, radio frequency (RF) signals, solar power, and so forth and using it to offset power requirements by the devices and equipments. RF‐EH 2 is based out of the fact that information and energy can be carried simultaneously by RF signals in 3 KHz–300 GHz band. EH by using RF signals allows the recharge of storage elements like battery or super‐capacitors from the ambient RF signals 3 and enables them to be free from requirements of fixed electricity grids and traditional energy sources.…”

A dual-hop time-switched (TS) energy harvesting (EH) amplify forward (AF) relay system has been considered, which comprises three nodes: source (S), destination (D), and an energy harvesting relay (R), respectively. Besides the relay link, the proposed architecture has an additional direct link between the source and destination node. For this model, we derive the expressions for system outage probability and throughput. The proposed architecture shows significant performance increments in terms of system outage probability and throughput when compared with a traditional EH relay system having no direct link.

Powering Wireless sensor networks (WSN) is one of the most researched topics in the wireless field. Due to the density of such networks, conventional power sourcing using wires is not feasible. Furthermore, a sensor node (SN) in a WSN consumes small amounts of energy. Therefore, the SN can be charged wirelessly using a radio frequency (RF) power transmitter. This paper presents a solar-powered simultaneous wireless information and power transfer (SWIPT) transmitter design with dynamic power allocation (DPA). Moreover, a receiver design with separate energy harvesting (EH) and information decoding (ID) circuitries is adopted. DPA carries the communication signal on low-power subcarriers around the carrier frequency, while the energy signal is carried on a highpower continuous wave (CW) centered at the carrier frequency. DPA reduces the interference to external networks by limiting the high power signal to a few subcarriers. Furthermore, the split receiver design increases the harvested power at the EH circuit reservoir.
