Perform the nucleus graph of a WCDS graph.
[Go] = NL_G_WCDSNucleus(G,N)
WCDS graph.
List of master nodes (nucleus).
Output graph.
NL_G_WCDSNucleus computes the virtual topology between the master nodes N of the WCDS graph G (WIKIPEDIA). Two nucleus are connected together if they are direct neighbors or if there exists one slave node between them.
