[ns] Node Coordinates
Hi,I want to print the position of nodes at the start of the simulation on the terminal window, can anyone guide how to do that? I have included mobility pattern file in my tcl script for the node placement and position.Regards,Najma
[ns] How to get a reference of a node from AODV?
Hi everyone, here is the problem, i have added some code to the class Node to do some computations, i'm modifying the protocol AODV where i have to use the computations added in the class Node, but after looking at the class AODV composition there is just the address of the Node, not the reference to the whole structure of the Node. so my question is how to get the reference of the node that the AODV agent is associated to so that i can access the attributes and functions and of course my added code of the class Node? if any one can help, thx in advance . Xoce.
[ns] debugging by printf statement
Hi, I have made the changes to 802_11.cc and added printf statements to it (I have hereby attached a copy of the file). If you want to look for the changes I have done, you may search for [[[ printf(adaptiveListen's cw is %d\n, rTime) ]. But I do not see any such statement in the trace file produced. Where can I get to see this printed output. Please help. -- Regards, Sahil Sharma $25: for you a pizza and some beers with friends, for someone might change their lives. Think about it.
Re: [ns] Maximum dataRate_
Hello Abraham, For getting such information you need to understand trace file. You can check how much packet have been sent in particular time interval. Becasue trace is the output of what is happeing or how protocol is behaving in such settings. I hope it will help you.

I am currently working with ns-2.34. In the sendData function in mac-802_11.cc, I am manually setting the dataRate_. However, I am setting it to relatively large values (in the hundreds of Mbps). Is there a maximum limit to what I change this variable to, and how can I confirm the variable is properly being set? I've currently been using tracegraph to see the differences in results when using a small vs. a large dataRate_. Any help would be appreciated. Thanks in advance.
FW: [ns] How to get a reference of a node from AODV?
Hi Itishi and thanks for the reply, i know i have to create objects to access them, but currently in the class AODV.cc there only one variable index of type nsaddr_t which represents the address of the node [nsaddr_tindex;// IP Address of this node] but i don't know how to get the whole structure of Node because with this variable index i can't access the attributes of the node. in other words how to access classes AODV.cc and Node.cc from one to another? just by making them friends? for example if i put: $ns node-config -adhocRouting AODV, if i have a node N0 i want to get access to it from the AODV attached to it. Thank you very much again. Xoce. Date: Thu, 18 Apr 2013 06:31:23 +0800 From: itish...@yahoo.com Subject: Re: [ns] How to get a reference of a node from AODV? To: jose-...@hotmail.com; ns-users@ISI.EDU Hello Jose, For getting access to the node attribut you have to play with node.cc inside common folder in ns-2.34. It is basically how you access method of one class toanother in c++. so you have two classes aodv.cc and node.cc you have to create object of one of them to access methods and they have to be friend of each other. I hope it will give you sufficient hint for your task.

I have included mobility pattern file in my tcl script for the node placement and position.Regards,Najma Hi Najma, You can try this code in TCL script: set posx [$node1 set X_] puts $posx This will print out the X component of coordinates of node. Do the same thing for Y and Z (replace X_ with Y_ or Z_) (but actually you don't need the Z). Best regards,
[ns] Fwd: selfish node detection
Hi All, I am using Trust aware cluster head election in manet. How can we calculate the trust value for a node?and how can we isolate a selfish node once it has identified? I am using NS2.34. -- *--- prabha*
