SensorTag Project for Wireless Networking course

Background: Purpose of project is embedded software development where we implement proximity detection and seperation between two CC2650 sensortags
Tools used C, Contiki OS and Cooja, CC2650 SensorTag and UniFlash
****

Specific requirements:

1. Discover pair of devices with contact times of 15s or more with high probability
2. Estimate the total duration in which two nodes are in proximity
3. Discover that a node in proximity has moved away for 30s or more with high probability
4. Reduce power consumption as much as possible
