Passing through the transformation of wood to coal then to oil and gas, we find ourselves
fortunate to witness the next major transformation, which will lead us to the “New Energy …

In this paper, a two-hop amplify-and-forward relaying system, where an energy-constrained
relay node entirely depends on the energy scavenged from the source signal, is …

The popularity of the electric vehicles has been growing due to the concern of increase in
environmental pollution. In order to overcome the environmental issues, electric vehicles …

Wireless power transfer and energy harvesting have attracted a significant research
attention in terms of their application in cooperative relaying systems. Most of existing works …

This article illustrates the conclusions drawn from the development of Internet-of-Things (IoT)
systems intended to monitor the ambient parameters, including the quality of the air in …

Piezoelectric energy harvesters have great potential for achieving inexhaustible power
supply for small-scale electronic devices. However, the insufficient power-generation …

In Internet of Things (IoT) networks for carrying out environment monitoring tasks,
maintaining low energy consumption of IoT devices can prolong the lifetime of IoT but the …

Wireless sensor networks (WSNs) are spatially distributed sensor systems used to collect
precise data from a large area of interest. WSN is usually deployed in the off-grid, and its …

The existing passive wake-up receivers (WuRxs) are radio frequency identification (RFID)
tag based, which incur high cost and complexity. In this paper, we study cost-effective and …

This paper proposes a coordinated ambient/dedicated (CA/D) protocol where backscatter-
enabled combination sensors are optimized to harvest energy from intended radio …
