[ibr-dtn] [IBR DTN] Notification about at the beginning of a bundle reception

Hello all,

I am using a scenario in which there are 2 nodes (node 1 and node 2) running the IBR DTN project. In this scenario, I have node 1 will send a bundle for node 2 at instant "t1". Suppose, that the bundle will be received by node 2 at instant "t1+Δt".

My question is, is it a way for the node 2 to know at an instant 't2' if it is receiving a bundle from a neighboring node (node 1 in this case)?

So in this scenario, I want to get these information :

1/ at t2 ∉ [t1,t1+Δt] ==> node 2 checks and discovers that it is not receiving bundles from neighboring nodes 2/ at t2 ∈ [t1,t1+Δt] ==> node 2 checks and discovers that it is receiving a bundle from neighboring nodes

Best Regards, Farouk
