Hello,
I want to forward AODV messages over a tunnel (don't worry, it's not for a
wormhole attack).
its ok, but if it was my AODV network I will be worried. Tunneling is
not understood only if I know what network are you tunneling through!!
In the RFC3561 I can't find information about how to deal with the packet at
the tunnel endpoint.
IMHO, normal ways of packet tunnel
Should I increment the hopcount of a RREQ by one or by
the number of hops the tunnel has?
RREQ is not a packet, your question was on packets, that increment of
RREQ is done by AODV node received. So I think only once, because one
tunnel and between two aodv-nodes only.
Furthermore I'm wondering about which
address to use for the previous node at the tunnel endpoint. Should this be
the entrance of the tunnel or the "real" previous node?
nothing is real when you are tunneling, so use the node address of
tunnel start. Overall I think the routing performance will not be good
only if the network elements of the tunnel is not mobile.
If the tunnel entrance is used as previous node and the hopcount is only
incremented by one, the tunnel would be prefered compared to a connection
without a tunnel (like in wormhole attacks).
Not correct, you don't say your reason, so I don't know how to respond.
Is there some information on how to deal with a tunnel?
In MANET documents I don't think there is importance of using
tunneling, I think it is not prefered. If used it will be an attack so
I am worried about what are you doing :-)
