>Hello,
          Glad to meet you.I didn't even imagine that i will get
spontaneous response directly from the mentor behind this idea.Thank
you so much.i read the documentation pointed by you and ya i am clear
now to some extent.so now my job is
1.To implement OLSR in C
2.To implement OBAMP with Multi-tree construction and add it as a
plugin to OLSR.You said that at present the OBAMP plugin constructs
one OBAMP tree irrespective of the kinds of multimedia data and all
the data is forwarded without knowing the intended nodes)..so i think
i have to go for content based routing here.i.e,for different kinds of
multimedia data(like text,audio,video)the multicasting node should
first multicast the IGMP query request using the multicast address
224.0.0.1..All the nodes will receive this message and 2 membership
reports are multicast(In IGMP, a membership report is sent twice,one
after the another) using destination address equal to the multicast
address being reported(group id)..and by using this membership message
,a separate OBAMP tree is constructed for each kind of multimedia
data(this prevents the data from reaching non intended nodes).is my
perception right?If not please do say me where i am wrong.
3.And simulation of this environment using ns2.

And you said that i the last data for student proposal is 6th..so i'll
submit my proposal by tomorrow..and one more doubt..first i should
inform my deliverables to you and it's only then i have to go for
Student Proposal,right?

Regards,
Jayapriya Surendran.
