[ns] How to deal with Unable to alloc %d bytes
hi, all! Enviroment: Windows Server 2003 + Cygwin, 4GB memory I am simulating a P2P application for scalability. when the number of nodes increases to over 3000, the application always shows Unable to alloc %d bytes after running a few minutes. As far as I observed, the application took up about 1GB memory. Is there some one in the same situation and how to deal with it? Is it a ns2 bug? Thanks and Best Wishes. Kimi Zhang

[ns] disabling RTS/CTS does not work - RTSThreshold_ 3000
Dear NS users: I'm pretty new in ns sorry if the question is too trivial but I can't come with it. I put Mac/802_11 set RTSThreshold_ 3000 to disable RTS/CTS been the packe size 270. After the simulation the trace file shows RTS/CTS packets. Why is it so? I have seen this problen in the mailing list more than once but there is no solution that works in my case. Thanks, Patxi.

[ns] how to show delay time.... (DSDV , TORA)
Hi.. guys I tried to make simulation to show delay time, sending packets, and receiving packet (to see lost packet during transmission) if I send a packet from one node to the other. I used DSDV and TORA algorithm to do this. But until now, I haven't met a way how to write delay time in trace file. is there anyone can help me, please? Thanks for your all help. -- Regard A Kha

Re: [ns] Fwd: No rule to make target `...@v_stlobj@', needed by `depend', while re-makeing the ns-2.33
Hi, Just do, sudo yum install compat-gcc-34 compat-gcc-34-c++ As you must have understood, the above command will install a gcc/g++ version 3.4 compatibility in your system, but whenever you use gcc/g++ command, your system automatically takes the actuall gcc version of your OS (i.e version 4.3.0). So the trick is whenever you want to use the version 3.4, just replace gcc/g++ by gcc34/g++34 respectively. Regarding ns2.33 (or any ns2.XX) take a fresh ns-allinone-2.33, go to the ns-2.33 folder, In the 'Makefile.in' replace, c...@cc@ c...@cxx@ by CC=gcc34 CPP=g++34 then return to the 'ns-allinone-2.33' directory and start the normal installation process.

Hello everyone! I'm trying a simulation in which one node needs to communicate with a 802.11 network as well as a 802.16 BS.
