Hi mohamed abas
to generate mobility models for NS2 you can use BOONMOTION tool, it's free for download

Good morning

I am working in PHD degree (Ad Hoc Multicasting) , and I want to know how to Generate Mobility Models and use it in NS-2

Thank you for your support

This is the mailing list for the MANET WG of the IETF, working
on stanadardisation of ad hoc routing protocols rather than on
MANETs in general, so only some of your questions are in scope
here. For those

Is there any working group or interest group in this area?

Yes, this one, but in the limited sense of working on specific
proposals, not a general open-ended interest group.

How the metrics are standardised?

One of the two unicast routing protocols that this WG is
producing, OLSRv2, has a proposal for metrics with rough
consensus to incorporate into the draft, that proposal being
draft-dearlove-olsrv2-metrics-04 - that deliberately however
does not answer some of your questions, as it explains.
For the other unicast routing protocol this WG is working on,
DYMO, I will leave someone more up to date with the latest
state to answer.

Be careful with the random waypoint model. When wrongly tuned, it has  
been shown to have no stable configuration and average node speeds  
decrease and even freeze when the simulation last for too long time.  
In order to avoid this you must set the minimum speed parameter well  
above zero. Unfortunately most simulations results published so far  
does not satisfy this recommandation and are utterly wrong.

Hi

Reading [RFC2501] might be useful. In my opinion, establishing QoS metrics depends on the purpose of your MANET i.e. the guarantees you want to provide. 

[RFC2501] defines metrics to gauge routing efficiency and effectiveness for a general context MANET.

Arvind

There is a second problem with random waypoint that is not solved by
setting a high minimum speed. Take a random waypoint model, with
waypoints distributed independently and uniformly across an area (e.g.
a rectangular area). Now run it and collect whatever statistics you are
interested in - even for some ideal process. Now reduce the speed towards
zero and plot the trend. Then scatter the nodes statically across the area
and do the same. The liniting case of the first is not the second - because
while the waypoints are uniformly distributed, the node positions aren't,
they have a bias towards the centre.
