A method and a node for allocating spectrum efficiently in clusters of nodes

A computer program product comprising a non-transitory computer readable storage medium having computer readable program code embodied in the medium, the computer readable program code comprising computer readable code to perform:

• determining recursively a plurality of clusters of nodes by recursively increasing a size of the clusters, starting with clusters of size one and determining clusters with the increased size until all nodes are associated with a cluster;
• and assigning a bandwidth to each cluster, based on the size of the cluster.

A non-transitory computer readable memory configured to store executable instructions for a controlling node, the executable instructions when executed by one or more processors cause the controlling node to perform:

• determining recursively a plurality of clusters of nodes by recursively increasing a size of the clusters, starting with clusters of size one and determining clusters with the increased size until all nodes are associated with a cluster;
• and assigning a bandwidth to each cluster, based on the size of the cluster.

A controlling node comprising a processing circuitry, the processing circuitry comprising memory and a processor connected thereto, the memory containing instructions that, when executed, cause the processor to:

• determine recursively a plurality of clusters of nodes by recursively increasing a size of the clusters, starting with clusters of size one and determining clusters with the increased size until all nodes are associated with a cluster;
• and
• assign a bandwidth to each cluster, based on the size of the cluster.
