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 ...

A novel model to eliminate the doubly near‐far problem in wireless powered communication network
IET Communications, Volume 15, Issue 12, Page 1539-1547, July 2021., 2021 Abstract In this paper, the newly emerging wireless powered communication network is studied. In doing so, the performance of the global controller (GC) is evaluated, which coordinates the wireless energy transmissions between two sensor nodes. Both the sensors have the same harvested energy for uplink (UL) transmission of information through time ...
