Built a custom MQTT (Message Queuing Telemetry Transport) broker from scratch using C programming language to understand low-level network programming, packet composition, and concurrent client handling.

Key Learning Objectives:

  • Understanding C programming fundamentals and memory management
  • Learning packet composition and protocol implementation
  • Exploring client-server connection management
  • Implementing multithreading for concurrent client handling
  • Gaining experience with socket programming and TCP/IP networking

Technical Implementation:

  • Core MQTT Logic: mqtt.c and mqtt.h for protocol implementation
  • Network Layer: network.c and network.h for connection management
  • Packet Handling: pack.c and pack.h for message composition and parsing
  • Socket Programming: Low-level TCP/IP socket implementation
  • Concurrent Processing: Multithreading support for multiple client connections
  • Protocol Compliance: Custom implementation of MQTT messaging protocol

Skills Developed:

  • Low-level C programming and system-level networking
  • Understanding of IoT communication protocols
  • Socket programming and network architecture design
  • Concurrent programming and thread management
