[ns] Not receiving data packets at agent.

[Madhava N]

Hi all,
   I have written a new MANET routing protocol by reading the document of
Franscisco and Pedro. I am facing a problem that data packets are not at all
received by the routing Agent.

That is at recv() function it is only receiving the HELLO (defined by me)
packets. But the recv function is same as OLSR or AODV or DSDV which
receives data packets as well.

Also, I noted that if-queue parameter which i have used is never set. What
could be the problem that I am unable to get the data packets at all.

Any help is greatly appreciated.

Regards,
Maddy

[ns] Segmentation Fault when implementing a new protocol

[Madhava N]

Hi All,
   I have implemented a Layer 3 routing protocol by reading the document by
Francisco  Pedro. I installed NS2, added my protocol  did make.

Make worked without errors, but when I run a simulation script (the same
script used for AODV) specifying my protocol as option I am getting
segmentation fault. Does anyone know what could be the reason behind this.

My protocol is a MANET protocol based on AODV  OLSR and I am using NS 2.31
for my simulation. Please let me know some of the possible causes for
segmentation faults in NS2.


*Thanks  Regards,

Re: [ns] packets generated number

[Madhava N]

Not sure of built in commands but you can call in TCL like disp_count and in
command function call a function and display.

For this maintain array of countpkt[n] where n is no of nodes. Keep
incrementing for every timer expiry of Hello + forward() function + send
functions. Better have it as static variable.

[ns] Link Bandwidth Estimation in NS2

[Madhava N]

The *chapter 9 (Delays  Links)* of the NS Document gives the details of
finding out the Link bandwidth, latency and transmission time of a given
link.

I am implementing a new protocol in NS2 for Mesh Networking and want to make
use of this in my protocol. If at least I were to be told on how to
modify *AODV
for the same *would also be helpful.

My question is that how to make use of this to *measure these details* in
our protocol. Like use these functions and *obtain the link characteristics*
.

Please do let me know on this.

Regards,
 Madhava.
