[ns] some of DSR parameters

[Dasha Stepanova]

Dear ns-users,

I am new user of ns-2. I am doing a simulation using dsr routing protocols. Now I have several problems with my ns-scenario. I need somehow change range of nodes from 250m to 500m. I found a few ways how to do this but no one is clear for me.
Other problem how to define number of “ad hoc hops”, it should be 2 in my case. 

Thank you in advance
Dasha
