Re: [ns] NOAH Patch with NS-2.2[789]
Hi I have been using this NOAH patch with ns-2.28. Hope it also works with other versions. Sincerely, Alexander Sayenko (PhD) Senior Assistant Telecommunication laboratory, MIT department University of Jyvaskyla, Finland Hi guys, I have been fightin with the NOAH patch for over sometime now. Has anybody worked on NOAH extension for NS2 before? I tried patchin (atleast followin d instructions on the NOAH page which do not include recompilin NS2 even though if I try recompilin it fails). I really need to make this work. Any suggestion will be appreciated. Note, If there's any alternative of extension that can perform the Infrastructure Network facility of wireless communication btw mobile nodes will b appreciated. Pls, anybody with success story on NOAH with NS-2.29, NS-2.28, NS-2.27should pls share it. Thnx. Lekkie. -- No virus found in this incoming message. Checked by AVG Free Edition.

[ns] [Fwd: Ad Hoc in Point-to-Multipoint with CBR]

Hello,
I am working with AODV, DSDV and DSR in point-to-multipoint and
multipoint-to-point scenario with 11 nodes.
In the multipoint-to-point scenario, the senders starts a CBR traffic to
the receiver with 1 second interval and, after 11 seconds, as expected,
there are 10 simultaneous flows.
The problem occurs in the point-to-multipoint scenario. The sender starts
a CBR traffic to all receivers with 1 second interval, so after 11
seconds, there supposed to be 10 flows from the sender to the receivers,
but in fact, there are only 3 simultaneous flows. Does anyone know the
reason?
I am appending a shell script file and the TCL file.
Thanks in advance.
Etienne Oliveira.

[ns] Problem adding extra fields hdr_cmn structure
I want to add an extra field in the Hdr_cmn structure (in packet.h). Lets
just say the extra field is : MyValue.
- At the routing layer, I modified the value of this field.
- At the Physical layer (wireless-phy.cc), I take some actions based on the
value of MyValue.
To my surprise, even though I set this value in the routing layer as 1, at
the physical layer, when I read it, its always 0.
I can't understand why.
Besides adding this field in the cmn_hdr structure, do I need to do
anything else ? (I didn't add the inline functions etc.)
I attached a part of the packet.h file. The only modification I made is
between the ** lines.
Thanks a lot for your help.

Re: [ns] Help, Problem with MPLS module on NS 2.26
The solution was the manual correction of the makefile. But in fact the problem came from the version of the compiler I was using. With ns 2.6 the recommended version of gcc is 2.95.3. Using this compiler solves most of the problems. I am going to post an install guide a bit later on this mailing list. Regards, Gilles Bertrand Telecom INT (GET) University of Stuttgart Paulo Cezar Soares a écrit : Hi, I checked the ns-users list and verify that you has a problem with MPLS module on NS 2.26 with the follow error: (_o3 cmd line 1) invoked from within _o3 cmd configure-ldp-on-all-mpls-nodes invoked from within catch $self cmd $args ret (procedure _o3 line 2) (SplitObject unknown line 2) invoked from within $ns configure-ldp-on-all-mpls-nodes (file /ns-allinone-2.26/ns-2.26/tcl/ex/mns_v2.0/test-constraint-routing.tcl line 140) Could you share your solution with me, or indicate Install Guide of MNS v2.0 for NS 2.26 ?

[ns] Bluetooth and 802.11 performance
Hi All, I want to study bluetooth performance with 802.11 devices. I was just wondering as to how to specify bluetooth in ns-2. Also I am not sure as to how to specify large number of mixed 802.11 and bluetooth nodes together.Please help me. Thanks in Advance, Manish Ph.Dc - Talk is cheap. Use Yahoo!
