LightWeight, energy-efficient, and end-to-end secure Publish-Subscribe system based on MQTT (LWPubSub)

Application code of the paper: "Junior, N., Silva, A., Guelfi, A., Azevedo, M., & Kofuji, S. (2021). Lightweight and Secure Publish-Subscribe System for Cloud-Connected Ultra Low Power IoT Devices. Journal of Communication and Information Systems, 36(1), 110–113. https://doi.org/10.14209/jcis.2021.11"

This repository contains:

• LWPubSub application for Constrained Wireless IoT devices (CWIoT)
• LWPubSub IoT Agent (based on FIWARE IoT Agent for MQTT)
• FIWARE-based cloud platform

• Install docker and docker-compose
• Create the container images:

cd cloud_platform; ./cloud-platform-services create

• Using 'terminator' (on Ubuntu: apt-get install terminator):
  • Open 5 "sub-terminals":
    • 1st for cloud-platform commands (start and provision device)
      • Inside 'cloud_platform/' directory, execute: ./cloud-platform-services start
    • After, run: ./new-provisioning.sh to provision the CWIoT (Sensortag, Remote, Native)
      • 2nd for local MQTT Broker - use mosquitto_sub (view all specific MQTT messages)
        • Execute: mosquitto_sub -t "#" -v
      • 3th to check IoT Agent messages:
        • Execute: ./view_logs.sh
  • 4th to run the device:
    • Native target simulates the CWIoT. It is required to insert the lwpubsub_system inside the examples/ folder of Contiki-NG (we use the version 4.4)
    • After installing Contiki-NG, we need to compile the code, running ./make_lwpubsub_native-cloud_cwiot.sh
    • Then execute: sudo ./lwsec-pubsub-system.native
      • 5th to check delivered MQTT messages to the cloud platform
