[ns] One interface with two channels

[Miguel Pereira]

Hello

I'm trying to implement a new mac protocol, similarly with 802.11. Now I
need to create one uplink channel and one downlink channel, to have
simultaneously transmissions.
To achieve that, I only found the perspective multi-channel with
multi-interface, that is not what I want. What I really want is one
interface with support to two channels, because I need to preserve just one
mac layer per node.

Is this possible?
What I need to change to achieve this?

I'm thinking to create a new add-interface method on ns-mobilenode.tcl, with
two channels for one interface, is this valid?


Thanks for any feedback and any help.
