[ns] need help regarding, monitoring a link from one to another node

[muralikrishna g]

hi to all..

1) here i have to get a xgraph for the link from one node to another node..
i have to get graph time vs traffic over the link, like
 n1--n2--n3--n4
how to get xgraph for the link n1 to n4

i know how to get a graph for the amount of traffic received by a node over
the time..
but

2) i dont know how to get xgraph for the amount traffic passed through the
node..

please help me regarding the above two queries.. please respond i am in need

thanks in advance

hi to all..

i have asked here how to find the node id in classifier.. but i didnt get
any response as i need, but luckily i got solution.. that is name ( ) will
write the node id's in classifier...

here again my question that.. the node ids i get in tcl code via puts
$node(n) here it writes node n id..

but i am not getting this id value in classifier... name function writes
different ids those are not written by tcl code..

how do i get same node ids in both classifier.cc and node.cc

 Hi all,

 I want to simulate sensor networks in ns2. Specifically, I want to model
 sensor nodes with following capabilities:

 1. Sensing channel and sensing model
 2. Battery model
 3. Processing Power model with processor voltage and frequency.

 Previously, a part of it was available in ns2 by UCLA in SensorSim at:

 http://nesl.ee.ucla.edu/projects/sensorsim/

 But now they have removed the code from there. If any body has the
 downloaded code from there or have the battery model and processing model
 etc., please let me know from where I can get it. I really need that to get
 my sensor network simulations working. Thanks!

 Regards,
 Arslan
