Hi all,

The ship example below is an example of a MANET application scenario that we have experienced in Saudi Aramco. We have a maintenance barge that is primarily connected to the network via a relatively low-speed VSAT (satellite) link but could take advantage of the proximity to infrastructure to connect via WiMax and achieve higher data rates and lower latency. It is true that we're currently using OSPF for that, but that's just because the area where this particular ship roams within is confined in a way that enables us to do so using a distributed VLAN. A more flexible and general design to opportunistically take advantage of the vicinity to fixed communication facilities (hosted in a fiber connected offshore platform) would require a MANET protocol. A MANET protocol would also enable maintenance and security boats to relay traffic through boats closer to the maintenance ship or the fixed infrastructure (usually an offshore platform). This is a very real business application where the value of MANET is in opportunistically establishing better connectivity for moving vessels.

Jens,

If you are only worrying about the LAN at the fringe of the internet,
then your logic is entirely correct.
        (LAN is defined as reach from last router to end systems; don't get
sidetracked into geo footprint definitions).

But increasingly we have a radio-WAN problem where the RF network is
purely a router-router interconnect problem.  End systems are on the
other side of at least one router.  A fairly mature example is a ship
which may have many end systems within the ship (a LAN problem).  But it
needs to interconnect ashore -- a router in the radio shack on the ship
connected to a router at the communications station ashore.
        There are other good examples of the radio-WAN  problem, and many more
so if your crystal ball is in operating order.  Consider a large size
disaster response -- a multi-engine fire response is a good case.  The
fire engine may host multiple end systems, so it's analogous to the ship
in the anecdote above.  So the routers on each engine need to be able to
form a radio-WAN that reaches back to the cabled internet at first
opportunity.
        How long until this is the case in your private automobile.  Right now
you have an end system -- a cellphone or PDA so we tend to visualize it
as a LAN problem.  But instrument a few more things and export the data
from a few more of those things and you're into the LAN-in-car mode and
a radio-WAN router-router interconnect problem to the rest of the
internet.
