Relay Selection for Capacity Increase in Underwater Acoustic Sensor Network

Sensors, 2021
In long distance sensor nodes, propagation delay is the most crucial factor for the successful transmission of data packets in underwater acoustic sensors networks (UWAs). Therefore, to cope with the problem of propagation delay, we propose examining and

Exploring Topological Semi-Metals for Interconnects

Journal of Low Power Electronics and Applications, 2023
The size of transistors has drastically reduced over the years. Interconnects have likewise also been scaled down. Today, conventional copper (Cu)-based interconnects face a significant impediment to further scaling since their electrical conductivity ...

Investigation of the Effect of Intra-Cavity Propagation Delay in Secure Optical Communication Using Chaotic Semiconductor Lasers

Photonics, 2019
The influence of intra-cavity propagation delay in message encoding and decoding using chaotic semiconductor lasers is numerically investigated. A message is encoded at the transmitter laser by a chaos shift keying scheme and is decoded at the receiver ...

Analysis of flight delay propagation characteristics based on complex network propagation dynamics [PDF]

Journal of Hebei University of Science and Technology
In order to address the problem that the existing susceptible-infected-recovered(SIR) model does not consider the impact of the topology of the airport network on the flight delay propagation, the topological characteristic index of the airport network ...

Joint Algorithm for Multi-Hop Localization and Time Synchronization in Underwater Sensors Networks Using Single Anchor

IEEE Access, 2021
In this study, an effort to synchronize and localize the underwater sensors simultaneously in a multi-hop environment is considered. Underwater Sensor Networks (UWSNs) has limited range and connectivity due to propagation delay and limited bandwidth.
