Setting up router agent to use custom PHY (phy2) to send data from simulated modem to real modem

Question

I am working on an attribute based routing protocol, where source node (Node A) collect attributes from two neighbor nodes (Node B and C) and based on ranking, Node A decides,to forward its data either to Node B or Node C

Now, to test this algorithm in testbed with only two real UnetStack modems, as per the answer (by Prof. Mandar Chitre) to my previous post Is there a way to trasnmit and receive data between simulated and real modem in UnetStack I have implemented a phy2 PHYSICAL agent, using UnetSocket, as a proxy to send data to real modem.

However, now I am able to send data from Node B (gateway node) in simulation subnet to Node B in another subnet from phy2, but I want to send data using router. Please let me know, how I can setup router agent to use phy2.

Answer 1

The acoustic channel is not shared between the simulated and real modem, since the simulated modem can't transmit real sound in water, and so a real modem can't "hear" the simulated modem.

However, you could consider sending your information over a different link (e.g. UdpLink) that can send messages between a simulated node and a real modem, as long as both are connected to the same subnet over IP.

In fact, if you wanted a even closer simulation to your network, you could add an agent to the modem that would listen to the DatagramNtf from UdpLink and send an equivalent RxFrameNtf to topic(phy), simulating a frame that came over the acoustic channel.
