[ns] Route error in DSR
Hello
I am using ns-2 for the first time to run a simulation in an ad hoc wireless
network. I use DSR as routing protocol, but I have a problem with routes
breaking and not getting rerouted. The network is dense, so several routes are
always possible. The traffic load is low, so there is capacity left over.
The problem arises when the route is broken between a relaying node and the
destination. The behavior is the following:
The source does not get notified.
The relaying node buffers packets until the buffer is full, then it drops the
packets.
The source keeps sending packets to the relaying node.
The traffic is CBR over UDP, so no acknowledgment end-to-end is present.
My question is: Is not route error notification implemented in DSR in ns-2 (I
use ns-2.1b7a on Linux)? Also, if someone has a tcl-script for a multi hop DSR
simulation that works I would appreciate to take a look at it. In the example
scripts in the ns distribution I only found single hop communication.
