Design Example: Design of an Irrigation Channel

162
Trapezoidal channels are widely used in irrigation systems due to their cost-effectiveness and efficiency in conveying water. Trapezoidal channels feature a flat bottom and sloping sides, making them stable and easier to construct compared to other shapes. The bottom width and side slope ratio are determined based on the required flow capacity and site conditions. The side slope is kept gentle for unlined channels to prevent soil erosion.Hydraulic parameters in channel design include the flow...

Pilot and Numeric Relaying01:21

Pilot and Numeric Relaying

120
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:

Background:

  • Smart agriculture integrates traditional farming with advanced technologies like IoT, cloud computing, and AI.
  • This integration introduces significant information security challenges, particularly for resource-constrained IoT devices.

Purpose of the Study:

  • To propose and evaluate lightweight cryptography techniques for securing IoT ecosystems in smart agriculture.
  • To address the urgent need for robust information security in precision agriculture.

Main Methods:

  • Integration of lightweight cryptography into the IoT ecosystem for smart agriculture.
  • Adoption of the Expeditious Cipher (X-cipher) for secure communication channels within the Message Queue Telemetry Transport (MQTT) protocol.
  • Case study focused on smart irrigation systems to protect sensor data and irrigation decisions.

Main Results:

  • The X-cipher protocol demonstrated improved power consumption, execution time, and memory usage compared to the Advanced Encryption Standard (AES).
  • X-cipher outperformed the PRESENT lightweight encryption protocol in throughput and memory usage.
  • Secure channels protected sensor data from eavesdropping and unauthorized modifications, and secured irrigation decisions.

Conclusions:
