IoT – CoAP, MQTT & Energy Consumption Analysis

This repository, covering Wireshark packet sniffing for CoAP/MQTT and energy consumption estimation for IoT devices based on measured data.

Project Overview

The project has two main parts:

1. Packet Sniffing & Analysis (Wireshark)

   • CoAP confirmable/non-confirmable GET and PUT requests
   • MQTT client connections, subscriptions, and Last Will messages
   • Topic filtering with/without wildcards
   • Retained MQTT publishes

2. Energy Consumption Estimation

   • Analysis of CSV power measurement files:
     • transmission_power.csv
     • deep_sleep.csv
     • sensor_read.csv
   • Computation of:
     • Cycle duration
     • Energy per cycle

Features

• Wireshark Filters for isolating specific CoAP/MQTT traffic patterns.
• Statistical results for:
  • Failed confirmable PUT requests
  • Equal confirmable & non-confirmable GET counts
  • MQTT client ID extraction
  • Last Will topic analysis
  • Retained message count

Key Results

• Packet Analysis:
  • 22 failed confirmable PUT requests
  • 3 resources with equal confirmable & non-confirmable GET requests
  • 4 MQTT clients using multi-level wildcards
  • 1 MQTT client with a "university" Last Will topic
