IoT Wireless Networking Projects

Selected wireless networking and IoT systems projects from CS4222 Wireless Networking.

Overview

This repository collects three embedded wireless systems projects built with Contiki-NG and the TI SensorTag CC2650 platform. The projects focus on sensor-driven state machines, low-level wireless communication with NullNet, and link-aware data transfer over intermittent wireless contact.

Projects

• Project 1: Sensor State Machine Sensor-driven buzzer control and event handling using motion and light thresholds.
• Project 2: NullNet Unicast Communication One-to-one packet transmission and reception with RSSI logging on Contiki-NG.
• Project 3: Link-Aware Sensor Data Transfer Discovery, link evaluation, and ACK-based chunked transfer of sensor data between wireless nodes.

Platform and Tools

• C
• Contiki-NG
• NullNet
• TI SensorTag CC2650
• Embedded sensing and radio communication

Notes

• The code was originally developed for CS4222 Wireless Networking.
• The repository focuses on source code and rewritten documentation rather than coursework submission artifacts.
• Build instructions depend on a Contiki-NG workspace and SensorTag CC2650 target configuration.
