Re: [ns] multicast support for wireless nodes



I get it. are you by any chance implying that i meant to say to use the same
multicast protocol for both wired and wireless. that was not my intention. i
meant that the folks at isi have implemented ODMRP, a multicast protocol for
ad hoc networks, on ns. So we can use that for multipcast in the wireless
domain. you would still have to use traditional protocols in the wired
domain and a combination of both in mixed scenarios. in fact, as part of our
class project we are implementing ODMRP and are almost done with it modulo
perfect validation.
