Daniel, Thanks for the reply! I read your paper (Unified Development and Deployment of Network Protocols). If I understand this correctly, it looks like it does not encapsulate the MAC layer. In the firmware I need to simulate, it has its own MAC and custom packet structure. I really need to simulate the MAC with my network protocol, is it possible to use GEA for this? If so, what modifications would be required?

To do so we implemented a small adaptation library called GEA. Maybe this could be of help for you. But it would require some modifications to your code (depending on the way the firmware is implemented). There is also a project/extension that allows to use the native TCP/IP stacks of different operating systems in ns-2 (called network craddles). I do not know more about this but you will find a link on the Contributed Code page in the ns-2 wiki. Maybe this could be a solution. The last chance would be to use network emulation. Daniel.
