AUTOMATIC ROUTING IN A MESH NETWORK OF WIRELESS MESSAGING DEVICES

A method of routing communication between nodes of at least one network including a mesh network is provided. The method includes each node of the mesh network advertising a hop distance relative to a head node of the mesh network. The hop distance is a measure of how many hops the node is from the head node, the head node having a hop distance of zero. Respective subscriber nodes of at least one subscriber node of the mesh network each transmit via an upstream route to the head node a request to subscribe to a topic of a plurality of possible topics, the upstream route being determined based on the hop distance advertised by first routing nodes included in the upstream route. Each first routing node records routing information that identifies the first routing node's adjacent downstream first routing node. The respective subscriber nodes subscribe to the corresponding topic for which it transmitted a request to subscribe. Subscribing to the corresponding topic provides the respective subscriber nodes with the ability to access contents of a published message associated with the corresponding topic.
