yes. of course. ns-2 can work that.y can search on google -- View this message in context: http://old.nabble.com/wired-cum-wireless-multi-hop-network-in-ns2-tp34264599p34270953.html Sent from the ns-users mailing list archive at Nabble.com.
Re: [ns] wired cum wireless multi hop network in ns2
Yes, you can. You can find useful information in the article Implementing a New Manet Unicast Routing Protocol in NS2 by Francisco J. Ros and Pedro M. Ruiz, and also in NS2 Document. From: Agepati Sujana suj...@ece.iisc.ernet.in To: ns-users@ISI.EDU Sent: Tuesday, August 7, 2012 2:23 PM Subject: [ns] wired cum wireless multi hop network in ns2 n0==b0--m0--m1--m2--m3--m4--b1==n1 here == means wired connection -- means wireles connection There is TCP source at n0 TCP sink at n1. m0 to m4 is adhoc multi hop network. is it possible to simulate above model in ns2?? I'm new to ns2.i have to simulate the above attached model. when i read the tutorials,i feel that once base station is used,all wireless nodes must be attached to it. but i require adhoc multi hop between wireless nodes so that data sent from wired node n0 reaches n1. Is it possible to simulate this in ns2?? please help me.i have spent weeks on this.still didnt get any idea how to do this... -sujana. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
Re: [ns] segmentation problem
Dear Sunil Kumar, Segmentation Fault is a very common problem faced by NS2 users. It has to do with memory such as trying to access an address that cannot physically be addressed, thus an exception has been called. It can happen either in C++ side or at TCL side. The below looks like happening from C++ side to me. Thought the problem is very common, unfortunately the cause of the Segmentation Fault are very wide. It takes more than providing couple of preceding error lines to solve it. The right way to handle a Segmentation Fault is by debugging the code. To start with, if your simulation scenario involves 50 nodes, see if you could replicate the problem in the smallest possible number of nodes to simplify your debugging process. For C++ debugging you can use GDB or even putting simple printf lines around node 0 received `UPD` from non-neighbor 5 lines to see if the change of variables, memory allocation and function calls are done per your need. It will take some time to understand how GDB codes work for first time user and a certain amount of troubleshooting effort., once you get used to it, it will be easy. After finding where the abnormality occur, work your way up the code to know what caused the abnormality and rectify the problem. Its very rare another person could able to help you to solve Segmentation Fault without looking at all the codes. Good Luck. rgds Saravanan Kandasamy On Wed, Aug 8, 2012 at 5:08 AM, sunil kumar scientist@gmail.com wrote: hello every one I am working with ns-2.35 in windows environment.

[ns] change aodv
Hi everybody I want to change the aodv code that each node send packet direct to destination without any middle node if the difference between the power that consumes for direct send and the power that consumes for sends packet to next node in the aodv protocol is less than the constant value, else follow the aodv best regards Heidari
