How to Achieve Energy-Efficient Communication in LoRaWAN? COV Algorithm Explained with Manthink Practice

In LoRaWAN-based IoT systems, reducing power consumption while maintaining data accuracy is critical. The COV (Change of Value) algorithm enables event-driven communication by transmitting data only when significant changes occur. This article explains the working principle of COV and demonstrates how Manthink implements it in EdgeBus and ThinkLink to optimize energy efficiency and network scalability.

1. Why Energy Efficiency Matters in LoRaWAN

As LoRaWAN deployments scale across smart cities, energy management, and industrial IoT, three challenges emerge:

Short battery life

Channel congestion

Limited scalability

The root cause:

👉 Excessive periodic data transmission

1. What is the COV Algorithm?

COV (Change of Value) is a threshold-based reporting mechanism.

👉 Data is transmitted only when changes exceed a predefined threshold

Example:

±0.5°C → No transmission

±2°C → Trigger transmission

This is also known as:

👉 Event-driven communication
