Due to the rapid growth of Wireless Communications devices, it is now believed that the relevance of Multi-Radio devices will highly increase in the near future. The research community has been trying to extend their analysis and simulation models so as to include this type of nodes.



This is also the case of the Network Simulator fr a mework, and there has recently been quite a large interest from its community to extend its mobile node architecture so as to be able to include more than one radio interface to work simultaneously.



After analyzing the different solutions that were available, we propose a set of changes to be done, so as to be able to use devices having multiple interfaces within the ns-2 fr a mework. These changes and modifications are summarized in the howto "Adding Multiple Interface Support in NS-2",
