Hello, DSR doesn't define which routing metric should be used. The implementation in ns-2 uses minumum hop.
>From the DSR draft - Each implementation of DSR at any node MAY choose any appropriate strategy and algorithm for searching its Route Cache and selecting a "best" route to the destination from among those found. The jitter helps reduce the number of potential collisions caused by multiple nodes replying to a route request at the same time.
