What does "Relay Node" mean?
Table of Contents
A relay node is a device used in wireless communication to help send data from one place to another, especially when the direct path has issues. These nodes act as helpers to improve connection quality when signals are weak due to long distances or obstacles like buildings or trees.
How Relay Nodes Work
When a device wants to send information but cannot do so directly, it can use a relay node. The relay node receives the data and then sends it to the intended destination. This process helps ensure that the information arrives safely and correctly, even in challenging situations.
Importance of Relay Nodes
Relay nodes are important because they enhance the reliability of communication networks. By using these nodes, connections can be stronger and more stable, which is especially useful in environments where obstacles might disrupt signals. This allows for better data transmission in various applications, including agriculture, remote monitoring, and more.
