Hi davide,
Basically there are four types of routing strategies in ns2.
1. Static
2. Session
3. Dynamic
4. Manual
And rtproto{} is an instance procedure in the class simulator that specifies
the unicast routing protocol to be used in the simulation. Basically session
routing provides complete and instantaneous routing changes in the topology
dynamics. For details see this link

And Session routing use Dijkstra Algorithm. So i think you should refer it.
