[ns] routing algorithm for wireless mesh network

[umair shah]

I asked earlier how can i develop routing protocol for wireless mesh network ,people recommended me to

but I ask you this is developing new routing protocol in ns2 ,so to develop that I must have my own routing algorithm ,right? How do I do that ,make my own routing algorithm ,i.e. clearify me that the protocol developed in ns2 have their own algos,how do I make my own,What should i study for that?
