Re: [ns] solution please
Hello,
The error is because the mobility pattern file was not found. Check the
correct path for the location of the Mobility pattern by checking where your
installation was done and edit the path accordingly.
Best regards!
in here
couldn't read file ../mobility/scene/cbr-3-test: no such file or directory
try to put your path to the directory for example
/home/sandy/ns-allinone-2.xx/ns-2.xx/tcl/mobility/secene/cbr-3-test

Hello any one
when i run the file wireless.tcl from ns tutorial for wireless
simulations for ns IX.2 from the link
http://www.isi.edu/nsnam/ns/tutorial/
i get the following error, can any one give me the solution?
and here is the out put of .tcl file
ns simple-wireless-1.tcl

Hello,
Would be easier to identify the errors if code is available...

[ns] location of node position using gps
Hello, I am working on a VANET simulations and i need to detect the position and speed of the nodes. I would want to know how the speed and the location of the nodes can be obtained using GPS.

Re: [ns] location of node position using gps
Hello Ajmal Thank you for your response! Having imported Mobility traces from SUMO and and now having tcl scripts of simulation i think these codes should be converted to tcl. I am clustering the vehicles based on the position and the speed of the nodes. Thanks Manfe Ajmal Khan wrote: Hi Here is the code to get the x and y coordinates and also a speed of a moving vehicle.

Re: [ns] location of node position using gps
Hello Ajma, SUMO is a portable, microscopic road traffic simulation platform. In my project Vehicular mobility is moduled using eWorld and imported to SUMO to generate vehicular traces. With MOVE, the vehicular taces are converted to tcl scripts. I am moulding a clustered network based on the speed and location of vehicular nodes using the generated tcl scripts.

Re: [ns] location of node position using gps
Hello Aslinda, Thanks for your contributions. You are perfectly right. All the simulators mentioned are basically the same the difference maybe added fucntionalities, capabilities and implementation platforms but at the end the results are the same;( TCL scripts) thats if it is being integrated in ns2. For clarification i would want to know from you, i am clustering the nodes generated from the TCl scripts, using the speed and location of nodes i however want to obtain these values dynamically in using TCL codes. I think i need to convert the c++ codes provided by Ajmal Manfe wrote: Hello Ajma, SUMO is a portable, microscopic road traffic simulation platform.
