Dear Faisal :
 
We are currently working on an intersting project called PAN (programmable ad hoc networks), that  investigates 
the  issues related to dynamically deploying/switching/modifying services/protocols in an MANET environmnet.  
Our objective is to come up with a context-aware middleware that can facilitate programmability in dynamic MANETs. 
We argued in our IM 2005 paper (see below for paper details) that this kind of programmability is important in MANET, 
as in MANETs the network  itself needs to be self-created, self-managed, self-optimised and so on. The above features 
of MANETs often require the ability to rapidly create, deploy and manage services and protocols in response to user 
demands and context. For example, while routing and Quality of Service (QoS) conform to standardised frameworks and 
protocols in fixed IP networks, there are many potential solutions for ad hoc networks that depend also on the characteristics 
of the particular ad hoc network, e.g. topology volatility, characteristics of radio links, capabilities of nodes, etc. Given 
the multitude of potential solutions that may be environment-dependent, programmability is of paramount importance to 
allow mobile nodes to be enhanced on the fly with the required capabilities in the ad hoc environment.
 
Although people can argue that this might involve some overhead, it is inevitable in the future MANETs, given that 
not only will there be hetrogeneous devises, but also we would have various complex services/protocols. In other words, 
in order to facilitate self-optimisation/self-management aspects based on the current context, dynamic switching/deploying of 
services/protocols at any level is important. As you mentioned in your mail, if a group (cluster) of MANET nodes are 
stationary for a while (or their relative velocity is minimal or zero w.r.t each other) and where almost every node is involved
 in some potential data transmissions (it may happen in battlefiel situation), it is better to use proactive routing protocols 
(together with some QoS mechanisms). On the other hand, when the relative mobility pattern is very random, then it is better to
use reactive routing protocols. Although, switch-over may involve some overhead, this strategy is still econmical if we are to 
conserve scarce resources.
 
Please refer to our IM paper, which investigates this problem through real test-bed experiments and simulations. The paper details
are as follows :

   Deployment of Services and Protocols in Ad hoc Networks, to appear in the Proceedings of  the 
   IEEE/IFIP Integrated Management Symposium (IM'2005), Nice, France, IEEE, May 2005. 
 
We hope this would help.

Subject: [manet] question about simultaneous use of different routing
        protocols in a single MANET

Hi all,
I was wondering if it is possible and practical to use two different routing
protocols in a single MANET ? I think if we are using two routing protocols
then it will make two segments of MANET and there must be a node (gateway)
between these segments which understands both routing protocols to relay
traffic from one segment to another.
On the other hand, if we want to switch from one routing protocol to another
depending upon the network conditions, will it be practical ? For example,
initially we have a proactive routing protocol running but after some time
the mobility of nodes increase considerably and the performance of proactive
routing protocol is decreased. Now if we want to switch to a reactive
routing protocol, will it incur a lot of overhead ? Is it practical ? If
someone has done any experiments of this kind please refer it to me.
Thanks.

Faisal.

Dear members,

I am a research student at Centre for Telecommunications and Information Engineering (CTIE),Monash University which develop MIPv6 use IPv6 suite on Omnet++.

I am wondering that is there any one who implement AODV protocol on Mobility Frame Work which is available on http://www.omnetpp.org

Thank you.
