Dear folks,

I'm currently starting some research on MANETs. My first impression
was, that there have been many protocols designed for a
wide variety of scenarios and preconditions, but that there was
not that much evaluation and simulation, that actually compared these
protocols, and is based upon scenarios that would be encountered in a real
applications.

One of the papers, that dealt with that issue is
"Scenario-based Performance Analysis of Routing Protocols
  for Mobile Ad-hoc Networks"[1], that was submitted to Mobicom 1999,
by Per Johannson et.al.
Then there have been some comparisons by Josh Broch et. al[2],
S.Das, C.Perkins, E.Royer[3] and S.Das, R.Castañeda, J.Yan[4].
Sung-Ju Lee also did some comparisons in [5].

Further there is some experience with a real testbed, built
by the Monarch project at CMU[6], and invidual simulations
presented along with the proposal of most of the routing
protocols.

Apart from these, I did not discover any other work, that focuses
on comparison and simulations. Especially with more sophisticated
movement and traffic models, like [1]. In [1], the authors state,
that this paper was just the advent of more simulations to come, comparing
more protocols and using other traffic models.
Unfortunately I was not able to find any papers about such
subsequent work.

If there is indeed more such work, I would be glad for a hint,
who did it, and where to get access to it.

My plans are, to develop a set of applications scenarios, that
model real situations and movements patterns as close as
possible. Further to use more sophistic traffic models,
e.g. TCP On-Off Traffic. Then, see how far this can be used
with simulations software (ns2, GloMoSim) in terms of acceptable
duration and data generated. If things worked out, I will do
actual simulations, to find what protocols are most suitable
for which situations.

Thanks for your help.

Best regards,
  Daniel
