Cognitive Relaying With Wireless Energy Harvesting and Accumulation
IEEE Systems Journal, 2021In this article, we propose a cognitive relaying (CR) scheme with both the secondary source (SS) and the secondary relay (SR) capable of harvesting wireless energy. Along with the data transmission of primary system, a power beacon actively transfers wireless power to SS and SR.

Throughput of wireless networks powered by energy harvesting
2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2011Designing mobile devices for harvesting ambient energy such as kinetic activities or electromagnetic radiation (EMR) will enable mobile networks to self sustain besides alleviate global warming. The throughput of a mobile ad hoc network powered by energy harvesting is analyzed in this paper using a stochastic-geometry approach. The transmitters powered
