Hello, I am doing simulation for 20 wireless nodes. Node 0 broadcasts a packet. I want to create a wormhole link between Node 18 and Node 19, where they are located far from each other. Before creating node 18, I have set Pt value higher to increase the transmission power of Node 18, but still the packet does not reach to Node 19 directly from Node 18. What may be the reason? If I increase the value more, for some of the cases, I get Segmentation Fault (Core Dump) error. I have created Nodes with agent Agent/Messagepassing. Is it possible to do only if I create the Nodes withe Agent/TCP? In that case, which node is required to be the agent of ACP and which should be of TCPSink for the same case? Thank you, Dhara Buch
