Hi all,

Is there a way to make only one communication at a time for each node.

Here is what I want to do: I have three nodes, node1, node2, and node3 connected between them.

At instant 't1', node1 sends bundles to node2 during [t1,t1+ΔT].

At another instant t2 ∈ [t1,t1+ΔT], node3 sends bundles to node1 and node2. Consequently at that time, I want : - node1 rejects the bundles of node3 because node1 is receiving bundles (is already in communication) - node2 reject the bundles of node3 because node2 is sending bundles to node1.

So, I want that a node can reject bundles if it is in communication (exchanging bundles with other node(s)).
