Abstract: A set of wireless nodes is provided, in which a subset of the wireless nodes are also wired nodes. A method of processing the set comprises performing a node initialisation, thereby linking nodes in the set of wireless nodes, performing a link evaluation, thereby determining a quality characteristic of links between nodes, and segmenting the nodes into partitions, each partition comprising at least one wired node and each node in a partition having a link to another node in the same partition with the determined quality characteristic above a predetermined threshold.
