In ns-3, there is no difference between the initial node position and
the changes in the node position and/or velocity. They are all reported
as a set of events which indicate that a new position/velocity is about
to take effect at a specific time. So, initial node positions are
usually reported as events for time 0.0.

In ns-3, you have to register with each layer for its packet events so,
the network layer is implicit when you get a packet event. The other
items might be problematic depending on your definition:
a) involved parties
c) packet comment
I assume that b) refers to a layer 4 port number. That number could be
made available to you but, only in layer 4 events. i.e., in the wifi
layer, you won't be able to read the layer 4 port number.
I have no idea what a) and c) really are so, I can't comment further.

We have no energy models in ns-3, so, the following is not relevant.

We have two types of links:
- point to point links: duplex with one pair of nodes interconnected.
- non-point to point links: multiple nodes potentially talking to all
We can, of course, report both of these to you: how do you want that
information to be formatted ?

We can easily tell you which nodes are potentially "interconnected"
through a wireless network. This does not mean that packet transmissions
between the two nodes will always (or ever) be successful though.
