We have identified this problem report as SPR-113276: "No data flow for video application in WiMAX" Known workarounds include: Upgrade the model to version 14.5 PL1 as we could get expected behavior under this release. Our staff will investigate this problem and provide a fix in a future release of OPNET products. You can check the status of the problem report by visiting OPNET Support Center (http://www.opnet.com/support/), clicking the "Technical Support" link, and then clicking the "Browse my Software Problem Reports" link. Alternately, you can contact technical support. We at OPNET are sorry that you have experienced this problem. We appreciate your patience. -- Hock S.

I have executed all three options myself: 1. Cygwin ns-2 installation This requires one to install cygwin ahead of time but its not complicated by any means. Just navigate your browser to www.cygwin.com and follow the instructions. Once cygwin is installed on your machine, then download the ns-2 all-in-one package from the ns-2 main site. Unpack it and follow the instructions; they are straight forward (./install). There are apparently some difference between the Windows and the Linux implementations of ns-2 but as I understand it, these differences are not significant. 2. ns-2 running natively on a Linux. For those of you already running Linux as your native OS, then simply download the latest ns-2 all-in-one release for your platform and follow the instructions accordingly. 3. ns-2 running within a Linux virtual machine on a Windows machine. VMware server is free and easily downloaded and installed (www. vmware.com/products/server/). This option allows you to run multiple guest operating systems on a Windows native host system. It has the convenience of not having to repartition your drive or install a secondary drive but introduces additional overhead of running Linux in a virtual machine. You want at least 1GB of RAM for this option and 2GB is preferred. Install Linux as a guest operating system, then download and install ns-2 all-in-one as above. Option #2 is probably the best choice if you are doing an ns-2 project ... in case there are implementation differences between the Windows and Linux ns-2. Option #3 may be a fair compromise. I use cygwin both at home in the office and it presents a very nice UNIX-like interface to a Windows machine and it has the added bonus of provisioning a decent X-server and ssh tools. In all cases, make sure you run the ns-2.31/validate command after your installation to confirm it was successful.

For your reference, I attach the PDF file of the tutorial in OPNET 11. Some features that the school's OPNET 11.0.A does not have include: - Antenna Pattern Editor (Page 6) - Radio transmitter and antenna modules (Page 18, 24) I believe that these are important modules for modeling a wireless network. Additionaly, this "Creating a Wireless Network" tutorial is listed under OPNET's Module Lessions. As mentioned in tutorial's main menu, "You may not have every special-purpose module". One possibility is that either these modules for OPNET 11 are not installed or they have been removed due to expiry. The good news is that, the school's OPNET 12.0.A, has these aforementioned modules and I am able to complete the corresponding "Creating a Wireless Network" tutorial. I will just use OPNET 12 from now on. Thank you! Best regards, Howard ****************************************************************************** From: Catherine Crosbie via Subject: [fas.sfu.ca #38416] fresh OPNET 12.0.A installation Date: Mon, 11 Feb 2008 16:30:41 -0800 To: ljilja@fas.sfu.ca CC: whrudey@sfu.ca, whrudey@telus.net Hi Ljiljana, As discussed, in case there are still unresolved issues with OPNET 12.0.A I completed a fresh installation in a new directory. To use the new installation, students should first back up their existing env_db12.0 file, then add the new path : Recommended sequence of commands: 1. mv ~/op_admin/env_db12.0 ~/op_admin/env_db12.0.bak 2. cd 3. setenv PATH /ensc/local2/opnet/12.0.A_PL5/12.0.A/sys/unix/bin:$PATH 4. opnet Catherine ****************************************************************************** To: Subject: Opnet 12 - workaround Date: Mon, 11 Feb 2008 08:04:20 -0800 From: "Will" Hello, To get around the Opnet 12 looping issue when you attempt to open the object palette, execute the following: 1. Ensure Opnet is not running. 2. Copy /ensc/local2/opnet/12.0.A/models/std/base/selfdesc.sddb to your local op_models directory ( ~/op_models). 3. Ensure the file permissions for this file are 755 4. Launch Opnet. This is essentially a workaround that really should have been noted in the tutorials for a multi-user server-based Opnet installation since Opnet wants to write to this file, students would be interleaving conflicting write ops. The payette installation doesn't allow writes by group or other, so it will always fail and arguably for good reason. The tutorials seem geared towards a Windows environment so there is not likely to be an issue with file permissions in a single user environment and hence the oversight in their tutorials.
