Re: [manet] AODV Question
See now I can't help myself either ;-)

I presume you mean why would anyone want to communicate with a node
255 hops away.
I don't think it is in the realm of science fiction to envisage much
larger networks
using MANET technology (such as those envisaged in pervasive or
ubiquitous
computing scenarios).
I know you disagree on this by the way as I was there for the
presentation of
your very good paper at PWC arguing this point*.
However, it can be argued that the uses of ad hoc networking technology
can be
envisaged to extend beyond the current focus of extending the reach of
base
stations and for use in laptops and PDAs. There is an argument (which I
hear
_alot_ from non-MANET people) which goes, why try to do this, surely
soon
the world will be one big hotspot?

Maybe an even
more important question is, would that route be usable? I think not...
Only extremely large ad hoc networks would have a radius of 255 hops
unless they are very stretched out. Besides, as people have already
pointed out, the IP ttl is already an 8-bit field.
On the above we totally agree.
