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.

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.
