DV routing in NS2

Hello, 
I'm working on a wired network simulation and i'm wondering is it possible to activate DV routing ($ns  rtproto DV) when a link congestion or packet loss occurs at a certain node, so it can redirect the traffic ? I know "$ns rtproto DV " works when a link goes down, it redirects the traffic to another path in order to reach the final destination. But in the situation of congestion/packet loss, is it possible to use it? If yes, how?
Thank you very much.
