the test scenario

Comment 2 Abhishek Sagar 2010-06-03 22:51:06 UTC

Well actually for the current test case provided I run into this error -
--assert failed. file=../src/internet-stack/ipv4-l3-protocol.cc, line=690, cond="interface >= 0"

and when the rectangle size is taken to be 450*450 (by editing the line nos 30 and 31) the error is this -
--assert failed. file=../src/devices/wifi/dcf-manager.cc, line=699, cond="m_lastNavStart < Simulator::Now ()"

test program that works with ns-3-dev

Comment 4 Nicola Baldo 2010-08-02 10:23:46 UTC

I updated the test program for ns-3-dev. It takes ages to run, but it terminates correctly without crashing. It is likely that this report originates from using an old release (3.7); therefore, I am closing this bug. Feel free to reopen it if you can come up with a program that crashes with ns-3-dev.
