Re: [ns] Ns-users Digest, Vol 45, Issue 6
Hey all, When I tried to install NOAH in NS-2.28 following the instruction by Monarch webpage,I found there was no Such NOAH in the Agent list. Then I thought I might "make" the ns again to let it update. However, A new problem came out. I entered the NS directory,type "make" or "make depend" ,there was always a error: "makefile 153: *** command commence before first target. Stop" Anyone knows or encountered this before? And Is NOAH not applicable under NS-2.28? And could we install more than two versions of NS-2? (Like NS-2.28 and NS-2.26) Thanks in advance! Regards, Joe

[ns] ns2.29 installing problem
Hello everyone
I installed ns 2.31 without any problem on centos5. but I couldn't install ns
allinone 2.29 on it. i changed the version of linux to FC6 but can't install it
again and i receive the same error.
i received this error:
*"checking system version (for dynamic loading)... ./configure: line
7624: syntax error near unexpected token ')'
./configure: line 7624: ' OSF*)'
tcl8.3.2 configuration failed! Exiting ...
Tcl is not part of the ns project. Please see www.Scriptics.com to see
if they have a fix for your problem."
and I received several solutions from ns-users:
1-
"The problem lies in how bash 3.1.x and 4.x.x parse the configure file. This
will simply pass through bash 3.0.x and lower versions. So in order to make
things work changed the following lines
tcl: file tcl8.x.x/unix/tcl.m4.
tk: file tk8.x.x/unix/tcl.m4.
otcl: file otcl-1.x/configure.in.
to:
system=MP-RAS-`awk ' { print $3 } '/etc/.relid`
"
2-
"modify file /home/nsuser/ns-allinone-2.29/nam-1.11/agent.h, on line
73,change the
character "NULL" to "0".
"
3-
"
I successfully installed ns-allinone-2.29.2 on FC5 but after
slightly modifying the whole package. First, I updated the Tcl and Tk
sources to the 8.4.13 (you can grab a copy from sf.net). Then you'll
have to modify the configure files (Tcl, Tk, OTcl and TclCL) in this
way:
cp -v configure{,.orig}
sed "s/relid'/relid/" configure.orig > configure
"
i tried above solutions but again i received the same error
and now i don't now how to solve this.
can anybody help me?

[ns] [NS] cbr problem in routing layer
I am using NS2 to simulate a reactive routing protocol. I want to send cbr traffic in a MANET. The design of the buffer is based on a map which key is dir ip and the second elment is a vector, where packets are stored. I copy the first packet in a buffer in order to send it before the source has found the route. As you can see, the next line launch the route discovery process: D 45.0 _3_ RTR NRTE 158 cbr 90 [0 0 0 0] --- [3:0 0:0 32 0] [0] 0 0 In the trace I can see that the packet is ready for sending: s 46.723228090 _3_ RTR --- 158 cbr 90 [0 0 0 0] --- [3:0 0:0 32 0] [0] 0 0 This code works correctly, but the problem is when I want to send the packet stored in my map. because it does not reach the MAC layer. And consecuently it is not sent. And the end of the trace I get the following line: D 105.0 _3_ IFQ END 158 cbr 90 [0 0 3 800] --- [3:0 0:0 32 0] [0] 0 0 Has anyone ever experienced this problem too? Thanks in advance Sara

[ns] Support for running ad hoc routing protocols for nodes in a LAN
Hi Friends. I wonder if it is possible to configure nodes in a LAN to run ad hoc routing protocols e.g OLSR? This would be very interesting for usage in a wired cum wireless scenario where both nodes in the ad hoc network and nodes in the fixed network can run the same routing protocol. Besides I wonder if ns2 supports nodes with multiple interfaces? Hope someone can answer these questions. Thanks for your replies. Regards Vinh Pham
