QL-TSCH-plus: A Q-learning Distributed Scheduling Algorithm for TSCH Networks

2023 IEEE 9th World Forum on Internet of Things (WF-IoT), 2023
Addressing the requirements of Industrial Internet of Things (IIoT) in Industry 4.0, the Time Slotted Channel Hopping (TSCH) protocol of the IEEE 802.15.4e amendment has been proposed. However, the lack of a defined scheduling procedure in the standard remains an open research area. Existing reinforcement learning-based scheduling proposals demonstrate

Characteristics and Variability of Precipitation Across Different Sectors of an Extra‐Tropical Cyclone: A Case Study Over the High‐Latitudes of the Southern Ocean

Journal of Geophysical Research: Atmospheres, Volume 128, Issue 22, 27 November 2023., 2023
Abstract Shipborne observations from the CAPRICORN‐2018 field campaign were used to investigate the characteristics and variability of precipitation across different sectors of an extra‐tropical cyclone on 16 February 2018, over the Southern Ocean (SO). Three distinct time periods—frontal, post‐frontal, and cyclone—were identified during the day.

An Efficient Anycast Mechanism for 802.15.4‐TSCH to Improve QoS in IIoT

Journal of Sensors, Volume 2023, Issue 1, 2023., 2023
The Industrial Internet of Things (IIoT) has emerged as a technology that automates industrial processes. In IIoT networks, data are collected from various nodes and sent to a base station for managerial purposes. However, in the industrial environment, network reliability and delay are significant challenges due to the high likelihood of packet loss ...

Biases in the thermodynamic structure over the Southern Ocean in ERA5 and their radiative implications

International Journal of Climatology, Volume 42, Issue 15, Page 7685-7702, 15 December 2022., 2022
The ERA5 reanalysis under‐represents the number of inferred cloud layers at high latitudes over the Southern Ocean. Cloud layers inferred from the ERA5 profiles are geometrically thinner and shallower than those inferred from the observed soundings. A fine‐resolution representation of thin multiple cloud layers can help reduce the shortwave radiation ...
