[ns] ported AODV implementation from Mahesh Marina

[Felix Ko <felix.ko@mchp.siemens.de>]

Hi all!

I have ported the AODV implementation from Mahesh
Marina's homepage, which was only compatible with
the cmu-wireless extensions...

The new version is compatible with ns2.1b7a, but still lacks
support for the energy model, because I currently don't use it...
Does anyone want to add it?

If anyone is interested, mail me!

There are only minor changes to Mahesh's code.
I copied the sourcecode formatting from Mahesh's sourcecode,
so the differences can easily be "diff"ed out...
I'm quite sure that it exactly does what the original cmu-sourcecode
did, but I have not extensively tested it!

My experiences so far:
1. it doesn't produce segmentation faults anymore (like the original ns2

implementation)
2. the performance is *much better* compared to the old code
(no details here...)

So long...

Felix
