7 Thread

The Thread protocol is a wireless personal area mesh networking protocol based on IEEE 802.15.4, IPv6 over Low-Power Wireless Personal Area Networks (6LoWPAN) and several Internet Engineering Task Force standards. Thread is maintained by the Thread Group, which ensures continuity between versions of the Thread protocol specification and certifies device interoperability.

A Thread network begins when a router-eligible device turns on but does not find an existing network. This device may then become the leader of a new Thread network, to which other devices may connect through a standard commissioning process as end devices. If an end device is router-eligible, it may be promoted to router within the Thread network as topology changes require.

Any router within the Thread network must be capable of being the leader. Routers within the Thread network participate in the forwarding and routing of network messages and are elected from the pool of router eligible end devices already in the network. End devices connect to routers and do not route for the Thread network. These end devices may operate as sleepy devices to save battery power.

The TI SimpleLink CC13x2 and CC26x2 SDK has a certified implementation of the Thread Protocol based on OpenThread. OpenThread is an open source implementation of the Thread protocol created and maintained by Google.
