[ns] WSN sending packets at variable rate.
Dear Everyone, In WSN, data packets are transmitted at constant interval. Is there any means by which data packets could be transmitted at variable intervals. Thanks in Advance. Thanks and Regards.
[ns] Changing node transmission power?
Hi, I was wondering if there is a way to change the transmission power of a node during the middle of the simulation. For instance, I would start off with the power as 0.2W but then later at t=20, I want to change it to 0.15W. Is this possible?

[ns] mac-tdma problem
Hi! I increased the 'max_node_num' variable to 200 and ran a simulation with many agents from different nodes sending to another node at the same time from a script. When I run the simulation with less than or equal 64 nodes, all the packages are received. When I run the simulation with more then 64 nodes (say 200), then packages are lost. Related to that, it seems from traces that when sending from an node agent A to another agent B (unicast), what actually happens is first another unknown application sends a package to B, then B replies to A to the application, then the actual unicast occurs. What application is that? When broadcasting, that application does not appear. If needed I can provide my script/agents. Thanks, Aurel __ Do You Yahoo!? Sie sind Spam leid? Yahoo!

[ns] [RE]tcl_find Library Invalid Command Name + xgraph error
If anyone else is having any of the same issues as me then the below should be
able to solve them. Ubuntu 9.10 doesn't work well with the NS-2 allinone
package. It fails to compile nam and xgraph despite changing to gcc. The method
outlined below has worked for me really quickly and easily without changes to
PATH.

p {margin-top:0px;margin-bottom:0px;}Hi,
I'm currently trying to run some sample of the sample code within NS-2 but I am
receiving the following error:
"nam: invalid command name "tcl_findLibrary"
Can anyone help?
Is this a problem with the PATH?
My Tcl library is currently pointing to (replacing username with my own):
TCL_LIB=/home/username/ns-allinone-2.34/tcl8.4.18/libraryexport
TCL_LIBRARY=$TCL_LIB:$USR_LIB
I am also getting the following error with xGraph
ns: close file5 ; _o3 finish stats1: couldn't execute "xgraph": no such file or
directory while executing
My PATH for xgraph is set up as:
XGRAPH=/home/username/ns-allinone-2.34/bin:/home/username/ns-allinone-2.34/tcl8.4.18/unix:/home/username/ns-allinone-2.34/tk8.4.18/unix
NS-2 compiled ok and validated ok.
Any help would be good.
Thanks,
Jethro

[ns] NS-2 and Ubuntu 9.10: Nam Access denied
p {margin-top:0px;margin-bottom:0px;}Hi,
I have installed the latest version of NS-2 on Ubuntu 9.10. So far I have had
no issues aside from some minor tweaks. I believe I have done everything that
has been needed (changing PATH etc) but I can't run any examples as nam is
producing an access denied message. I have tried Googling this but no one seems
to have offered an answer. Has anyone got a resolution to this?
The error I'm getting is below:
couldn't open "out.nam": permission denied while executing"open out.nam w"
invoked from within"set nf [open out.nam w]" (file "ns-simple.tcl" line 9)
Any help would be much appreciated.
Thanks,
Jethro
