Our project uses IPv6 (TCP/IP) stack for connectivity between nodes and connectivity to our server which handles most of the data.

Sensor node is connected to to internet via border router. We are writing a separate guide how to setup the border router with our setup.
This project is implemented using IoT-LAB M3 mcu boards and they have AT86RF231 radio chip. Radio chip is designed for IEEE 802.15.4 (LR-WPAN) standard (Low-rate wireless personal area networks).
6LoWPAN (IPv6 over Low-Power Wireless Personal Area Network)
Provides neighbor discovery, header compression like features and it is designed for low power devices with limiting processing capabilities.
RPL (Routing protocol for low power and lossy networks)
RPL is an IPv6-based routing protocol designed for energy-efficient communication in low-power and resource-constrained networks, commonly used in the Internet of Things (IoT) and industrial settings.

The Constrained Application Protocol (CoAP) is a lightweight and efficient communication protocol designed for resource-constrained devices in the Internet of Things (IoT). It operates over UDP and enables simple, low-power devices to exchange information in a RESTful manner.
