[ns] Assigning a port to a packet

2009-07-17 Thread Τσιλιγγίρης Γεώργιος
Hi to all, I implemented an agent that creates packets and sends them to nodes. The agent changes the destination of each packet in its IP header like this: hdrip-dest_.addr_=2 (or 3 or 4 etc.) It works fine with wired simulations but in wired-wireless scenarios I also have to declare the

Hi to all. I have two questions: Can I predefine the IP addresses of the nodes in my simulations? If I allocate a packet with an agent, change the destination address in the IP header and send it, will it go? Does the agent have to be connected to another one? George.
