[ns] Routing Metric of DSR

[venusian .]

Hieee,

DSR's routing metric is Minimum Hop, this means that if two routes are 
discovered
to the destination the one with minimum hop count will be selected by the 
destination
node. I'd like to know how is this feature incorporated in DSR i.e how r the 
routes
compared before sending replies. Is it the Random Jitter which allows the 
routes with lesser hops to b considered and returned in route reply.
If not how are the routes in packets compared and why is random jitter used 
before sending a route reply?

Thanking in Advance
Venuzian
