Pilot and Numeric Relaying

Pilot and Numeric Relaying

Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Light Acquisition

Light Acquisition

In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Carrier Transport

Carrier Transport

The generation of electrical current in semiconductors is fundamentally driven by two mechanisms: drift and diffusion. These processes are essential for the functionality and performance of semiconductor-based devices.
Drift Current:
The drift of charge carriers is started by an external electric field (E). Charged particles, such as electrons and holes, experience an acceleration between collisions with lattice atoms. For electrons, this results in a drift velocity (vd) given by:

Area of Science:

Wireless Communication Systems
Aerial Networks
Optical Wireless Communication

Background:

Conventional radio frequency (RF)-based unmanned aerial vehicle (UAV) swarm networks face challenges in achieving timely and reliable communication for aerial relay applications.
Existing RF solutions struggle to meet the stringent demands of ultra-reliable and low-latency communication (URLLC).

Purpose of the Study:

To investigate the integration of Light Fidelity (LiFi) as a supplementary wireless system for UAV swarm communication.
To analytically derive and evaluate the performance of LiFi-enabled UAV swarms, focusing on reliability, throughput, and latency.

Main Methods:

Analytical derivation of the average block error probability (ABEP) using Chebyshev approximation, including lower and upper bounds.
Development of expressions for key performance metrics (reliability, throughput, latency) as functions of the derived ABEP.
Numerical analysis exploring the impact of parameters such as blocklength, packet size, inter-UAV distance, signal-to-noise ratio (SNR), and light-emitting diode (LED) semi-angle.

Main Results:

The proposed LiFi system successfully meets the stringent requirements of ultra-reliable (99.99%) and low-latency (sub-millisecond) communication (URLLC).
These URLLC requirements are achievable even at low signal-to-noise ratio (SNR) values.
The study quantifies the influence of various operational parameters on system performance.

Conclusions:

LiFi offers a promising solution to overcome the limitations of RF-based communication in UAV swarms.
The findings demonstrate the feasibility of LiFi for supporting critical URLLC applications in aerial networks.
Further exploration of system parameters provides insights for optimizing LiFi deployment in UAV swarms.
