Maximizing Average Throughput of Cooperative Cognitive Radio Networks Based on Energy Harvesting

Sensors, 2022
Energy harvesting (EH) and cooperative communication techniques have been widely used in cognitive radio networks. However, most studies on throughput in energy-harvesting cooperative cognitive radio networks (EH-CCRNs) are end-to-end, which ignores the ...

Accurate supercapacitor modeling for energy-harvesting wireless sensor nodes

, 2011
Supercapacitors are often used in energy-harvesting wireless sensor nodes (EH-WSNs) to store harvested energy. Until now, research into the use of supercapacitors in EH-WSNs has considered them to be ideal or over-simplified, with non-ideal behavior ...
