Re: [ns] New Routing Protocol

[Haobo Yu <haoboy@packetdesign.com>]

Well, there isn't really a 'tutorial' on writing a new routing protocol,
and to write an ad hoc protocol is very different from writing a, say,
link state protocol.

I think part of the reason is there isn't a template for writing a routing
protocol, unless you only need some tweaks to the existing ones. For that
purpose, you want to read the routing agent chapter in ns manual, where
Kannan has a very nice structure of writing DV/linkstate/and_so_on
routing protocols. You can read his DV code, or Wang's link state code for
examples.

Otherwise, I'd suggest you start with node structure, how classifiers
work, and how current routing protocols are built. Then you can write your
own.
