I have created a mesh network algorithm for embedded systems. This implementation is released be released under MIT License.
Me and a friend have started an Internet Of Things project and we wanted to have a radio module to our microcontroller for communication. The radio module we choose was the NRF24L01+.
One question might arise: Why not use the NRF24Mesh[1] solution that’s already been developed? I’ve looked at the design and noticed that it could be improved which are mentioned in the features, and I also wanted to create it by myself, because I can 🙂
In this post I will discuss about the architectural design of the Mesh Network.
Features of this implementation:
Address range: ~2^18 addresses (262144).
Decentralized network topology: a master is needed, all grouping and addressing will be decentralized, which means that the closest “parent” is responsible to address it’s children’s.
Mesh with multiple routes: All the nodes in the network has always a “default” route to master. Nodes can also pair to other nodes in the network that is physically close. If node A and node B needs to communicate with each other they don’t need to send the packet via the master node, if there is an opportunity to send the packet to a physically near node, and the number of hops is less than via the master, the packet will be sent to that neighbour, which will route it onwards.
