[ns] Need OBS simulator
Hi, I am trying to create a simulation of a network that uses TCP over OBS using ns-2. The problem is that I can't download the OBS simulators that I found which are: 1. OIRC OBS-ns Simulator from http://wine.icu.ac.kr/~obsns/ 2. OBS-ns simulator from University of Maryland DAWN research lab (http://dawn.cs.umbc.edu/owns/) I can't download the first one because when I fill the form with my email and other information, I receive an email with a link to a page that says that this page is expired. The second one it's because when I try to follow the link http://dawn.cs.umbc.edu/owns/ says that I don't have access to that directory. Thanks for your time
[ns] TORA problem
HI,
I am using NS 2.31 on FC-6.
Whenver I run a TORA routing protocol , I get a message like given below.
But all other protocols like AODV, DSR and DSDV run smoothly.
So does any 1 have any clues??
The error is:
num_nodes is set 4

[ns] ERROR: Undefined symbol when making ns2 after code patch
All, Hello. I have an AIX box on which I am running ns2. I applied the patch for NOAH (http://icapeople.epfl.ch/widmer/uwb/ns-2/noah/), and then tried running ./configure, make clean and make in the directory ns-2.31, but am getting errors saying that I have undefined symbols. Has anyone run into this before? Any suggestions on how to fix this? Any help would be much appreciated.

[ns] LEACH installation
Hello all, Iam trying to install and run LEACH on ubuntu6.06. I followed the procedure from the site: http://tmtam.wordpress.com/2007/07/31/installing-ns-227-and-leach-extension-on-ubuntu-704-feisty-fawn/ and encountered the following problems on ./test: ./test num_nodes is set 3 warning: Please use -channel as shown in tcl/ex/wireless-mitf.tcl warning: no class variable Phy/WirelessPhy::alive_ see tcl-object.tcl in tclcl for info about this warning. warning: no class variable Phy/WirelessPhy::Efriss_amp_ warning: no class variable Phy/WirelessPhy::Etwo_ray_amp_ warning: no class variable Phy/WirelessPhy::EXcvr_ warning: no class variable Phy/WirelessPhy::sleep_ warning: no class variable Phy/WirelessPhy::ss_ warning: no class variable Phy/WirelessPhy::dist_ INITIALIZE THE LIST xListHead warning: no class variable Phy/WirelessPhy::alive_ see tcl-object.tcl in tclcl for info about this warning. warning: no class variable Phy/WirelessPhy::Efriss_amp_ warning: no class variable Phy/WirelessPhy::Etwo_ray_amp_ warning: no class variable Phy/WirelessPhy::EXcvr_ warning: no class variable Phy/WirelessPhy::sleep_ warning: no class variable Phy/WirelessPhy::ss_ warning: no class variable Phy/WirelessPhy::dist_ warning: no class variable Phy/WirelessPhy::alive_ see tcl-object.tcl in tclcl for info about this warning. warning: no class variable Phy/WirelessPhy::Efriss_amp_ warning: no class variable Phy/WirelessPhy::Etwo_ray_amp_ warning: no class variable Phy/WirelessPhy::EXcvr_ warning: no class variable Phy/WirelessPhy::sleep_ warning: no class variable Phy/WirelessPhy::ss_ warning: no class variable Phy/WirelessPhy::dist_ Loading connection pattern… Loading scenario file… Starting Simulation… channel.cc:sendUp - Calc highestAntennaZ_ and distCST_ highestAntennaZ_ = 1.5, distCST_ = 89.8 SORTING LISTS …DONE! NS EXITING… 1. Why is this happening? I guess the problem is with the inclusion of Phy/WirelessPhy channel. Where is it located in the ns2.27 folder? How do I verify if it is present? N How do I include it? When I execute validate, I get the outputs do not match standard results. Can you tell me where the problem lies? 2. Also once the GCC 4.1.x: ns-2.27-gcc410.patch patch is applied, nrlsensorsim extension for ns 2.27 is showing problems on installation. I had to omit that. 3. Do I have to install 802.15.4 layer support separately to simulate sensor networks? How do I do it? Kindly help. It is extremely important to me. -Sreevalli Send instant messages to your online friends http://uk.messenger.yahoo.com
