The idea of cooperative communication is to improve reliability of a wireless link between a source and a sink node by support of a third node, a relay node.
Say when nodes ϑ1 and ϑ3 interact not only through a third node, ϑ2, but also by means of a direct interaction.
The figure shows that the Gleason score values are inversely correlated with the expression levels of the module, defined by the first node of the hierarchical tree (red line on the figure), just like the four other regulators.
The second proposal of this work is forwarding data from a device out of communication range to the coordinator in real-time by a second type of relay node.
By convention, the first node receives the number zero (typically, this node denotes the class containing the application's main method).
Then, backtracking from the root to the leaves, we identify the corresponding clusters by picking the first node X, for which Q(X) = Q max (X).
Categorized text components were then condensed node by node a second time into shorter sentences [ 48].
As a result, the original digraph was derived into six disjointed components as shown in Fig. 6: one digraph with 11 nodes (A, C, D, E, L, R, M, J, S, T, U); a second digraph composed by three nodes (H, I and N); a third digraph with two nodes (B and F)); node K; node P; and node Q.
Alternatively, by introducing a second set of nodes representing the reactions, the hypergraph can be transformed into a bipartite graph with directed one-to-one edges (cf. Figure 1).
