Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 This paper focuses on the design of an optimal resource allocation scheme to maximize the energy efficiency (EE) in the wireless‐powered backscatter communication networks (WPBCN) with decode and forward (DF) relaying. The two different devices are supported to operate in different modes, the harvest‐then‐transmit (HTT) mode and backscatter ...

Throughput Maximization for Wireless Powered Buffer‐Aided Successive Relaying Networks
Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 In this paper, we consider a wireless powered cooperative network, where two energy‐constrained buffer‐aided relays harvest energy from the source to assist the information delivery to the destination. To improve the spectral efficiency, a wireless powered successive relaying (WPSR) protocol is proposed to allow both relays to receive the information ...

Modeling and Performance Analysis of ECS‐HTCARQ Protocol in Interference Scenario
Journal of Electrical and Computer Engineering, Volume 2022, Issue 1, 2022., 2022 To extend the lifetime of energy‐constrained wireless networks, this paper proposes a three‐node model of the wireless‐powered cooperative communication network (WPCCN). The model consists of an energy‐constrained source node, an energy‐sufficient relay node, and a destination node and considers two different cochannel interference (CCI) sources at the

Deep Learning‐Based Scheduling Scheme for IEEE 802.15.4e TSCH Network
Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 IEEE 802.15.4e time‐slotted channel hopping (TSCH) is one of the most reliable resources of the Industrial Internet of Things (IIoT). TSCH operates on the slot‐frame structure consisting of multiple channel‐offsets and multiple slot‐offsets. It is gaining acceptance due to its simple architecture and consume low power in industrial applications.

IET Communications, Volume 15, Issue 16, Page 2097-2110, October 2021., 2021 Abstract As a contention‐free channel access protocol, Time Division Multiple Access (TDMA) is widely applied in Energy Harvesting Wireless Sensor Networks (EH‐WSNs) due to ease of implementation. TDMA scheduling in EH‐WSNs faces the problem of low channel utilization since time slots assigned to some nodes may not be used by them due to shortage of ...
