[ns] IP spoofing of DSR route errors

[Salvo Danilo Giuffrida]

Hello, is it possible to send DSR Route Errors packets with source IP
addresses of other nodes? What I want to do, is to send Route Errors
from node X, but with source IP addresses of X's neighbors...It has to
do with a University project, to modify DSR in order for nodes to
relieve themselves when they reach a low level of energy, by forcing
nodes which generate traffic to use other routes (possibly, luckily,
which do not include the dying node). X will still be able to
send/receive/forward traffic, but hopefully won't be stressed too
much, if there are other routes to the intended destination, whose
nodes might have more energy...
Think of it like survival instinct, but the problem is that REERs are
normally sent from neighbors of X, when they sense (through the lack
of data-link ACKs) that the link Y->X is broken. If I'd simply shut
down X for an amount of time of 0.1-0.3 sec., this would happen
automatically, but I'd prefer to use a more "clean" approach, also
because X should still be able to communicate for a while, just not
too much, so it's better if it receive updates about the network
topology, such as RERRs from other nodes, etc...
Have you ever tried this approach? I'm asking this because I don't
have much time left, so I'd prefer not to waste time into ways that
will prove to be unfeasible...
Thanks a lot
