[ns] Multi-interface support howto

[Laurent Paquereau]

Ramón,

I have been reading your how-to and as your statements and concerns are 
quite similar to a subset of those we presented last year in [1], you 
might find interesting reading this paper.

[1] Laurent Paquereau and Bjarne E. Helvik, "A Module-based Wireless 
Node for ns-2", in Proceedings of the first Workshop on NS2: the IP 
network simulator (WNS2), Pisa, Italy, 2006.

A Module-based Wireless Node (MW-Node) is a Node with wireless and 
mobile capabilities added by means of modules. It is not a new node 
object derived from Node. Rather it is a new layout of mostly existing 
components. The aim is to provide a flexible support for wireless and 
mobile networking and in particular:
  * support for multiple interfaces/multiple channels, and
  * a common basis for the implementation of wireless routing protocols.

The code is distributed as a patch for ns-2.30 and is now available 
online with the documentation at: http://www.q2s.ntnu.no/~paquerea/ns.html

Feedback and comments are much appreciated.

Best regards,

Laurent Paquereau
