For my final year project, I am going to use a network simulator simply called ‘ns’. In order to simulate Mobile IPv6, I need to install the Mobiwan extension that has been written for ns by Thierry Ernst.

Unfortunately, it was last updated in December 2004 and only works on an older version of ns. (I’d already tried applying the extension to the latest version, ns-2.31 with no luck). This already had alarm bells ringing and so I set about installing the older, compatible version, ns2-27. However, there were some installation issues that as yet I am unable to resolve. I’m presently trying to run ns under Cygwin on Windows, but I’m not entirely confident that this will work either.

This leaves me with a few choices:

  1. I persevere and install ns.
  2. I use an alternative network simulator.
  3. I change the scope of the project.

Given where I am at in relation to the project, option 3 is out, and I’ll need to consult my Supervisor over option 2 so for initial time being, i might as well continue with option 1.

An update to this will (hopefully) appear later today.

I’ve managed to find nine seemingly relevant papers through the Web of Science, seven of which I’ve printed out. I’ll now spend the next few days reading them and trying to ascertain what it is they have and haven’t done, and what I could do different and/or better. This seems to be the challenge! I also need to get ns-2 installed on my home machine although with the latest release of Ubuntu 7.10, I’m worried about compatibility issues. I’m sure someone will be able to put my mind at ease on this one (paging Dr. O’Shea…).

I have just been using the Web of Science database which can be found through the University’s library page, www.leeds.ac.uk/library, and thus far it’s turned up several papers relating to Mobile IPv6 and specifically simulation and performance. The next stage is to go through the papers and ascertain what useful nuggets of information I can find.

Karim, my supervisor, mentioned to me that I need to also find information regarding other simulators so as to justify the decision to use the ns-2 network simulator. This might prove to be more difficult as I can’t think where I would find the kind of information that would allow such comparisons. I guess a good starting point would be to do a search with Google for ‘network simulators’ and then visit the websites of the differing programs.

I may need to find better sources of information for my report however…

Good afternoon! It’s a lovely Saturday afternoon in November and probably a little warmer than I would expect it to be!

Some of my friends are also doing final year projects and it had been suggested to them that they blog their experiences to keep a record of what goes on. With this in mind, I decided to do the same. It will hopefully prove useful not only when writing the personal reflections section of the report, but also give me an idea of what I was thinking about at a certain time. In other words, my memory is good, but not that good!

If you decide to follow my progress and wish to comment, please do so and hopefully it’ll help me in some way. I’ll also try and link to some blogs operated by others so you can see what they might be up to.

In the meantime, I hope you’re all having a good weekend thus far!

Attendance in advanced graphics on Thursday was particularly poor, in fact a mere 16 students turned up. This may well be due to the fact that some had spent all night previously completing coursework, but really thats not much of an excuse. Advanced graphics at the school of computing is one of the hardest modules you can take in the third year and I wouldn’t want to be missing any lectures, certainly not on a whim anyway.

Its amazing how much you can miss in just one lecture. On the few occasions I have had to legitimately miss a lecture its taken me nearly twice the duration of the missed lecture to catch up on all the work and in a pressured environment like the third year of a degree course I can’t understand how anyone has the time to perform such a catch up. I’d like to suggest that the simply don’t, in which case more fool them come exam time when they’re scratching their heads.

On the plus side if not many people attend then those that do get more interaction with the lecturer when it comes to asking questions and such which is clearly beneficial. It was certainly true that on Thursday those who attended managed to get a lot of our questions answered. Perhaps I actually like there being less people in the room.
