Ok Dasha, NS-2 requires lots of time! You'll get a good expertise in a year or more.
DSR is a routing protocol. Inside DSR (like every routing protocol in NS-2) you'll find a function recv(). recv() is the one which lower layers will call to pass packets. So, when a packet arrives, it goes layer-by-layer, recv()-by-recv(), until arrives DSR recv() at network layer. You must read DSR code and learn how DSR treat all income packets. You'll find where DSR do packet forwarding. So you can change the code to allow only 2 hops fowarding. In a wireless tcl file you can specify radio range. Take a look in wireless examples in ~ns/tcl/ex folder. Sidney Doria UFCG / Brazil 2008/10/26 Dasha Stepanova <[EMAIL PROTECTED]>: > > Dear ns-users, > > I am new user of ns-2.
