EMANE topology changes using democtl-host script #195

Open szl0144 opened 3 years ago

szl0144 commented 3 years ago

Hi,

I am trying to create a multi-hop topology where the traffics goes from node-1 to node-2, then goes from node-2 to node-3. Can I use the democrats-host script in the demo-start file to let the emanenode0 bridge only connects with node 1 (pass the node number parameter 1 into the script). Then adding a static route from node-1 to node-2 in the routing table of node 1 as well as adding a static route from node-2 to node-3 in the routing table of node 2? I am not sure if node-1 and node-2 will forward packets if I just connect one node to the emanenode0. Can you please give me some suggestions? Thanks!

Best, Shaoyi

You can use pathloss events or locations events (when using freespace or 2ray) to change topology. You can use static routes or you can use a MANET routing protocol. The emane-tutorial uses olsr. The letce2-tutorial uses batman-adv by default.

Hi,

Thank you for your suggestions. I am using static routes method to change the topology. I notice the source of the traffic generated by MGEN is port 5001 without the IP address. Without a source IP, It seems MGEN generates traffic for all three nodes through the port. Can you please tell me how to only let node-1 send packets? I can set the DST address (10.100.0.3/5001) for node-3 in MGEN right now.

Thank you very much. Best,
