Hi ns2 users, When I run some AODV simulation (50 nodes, 1500x300m), some scenarios are good for 4 packets /second, 20 sources, but cause core dump for 12 packets /second, 20 sources. The same scenario files work well for DSR. The ns2 version I use is 2.1b6a. Is there any improvement in the newest version? Liang Qin
