[ns] problem with TCP Cubic
Hi all... now i was doing my undergraduate thesis about TCP Cubic in Mobile IP network... i already download tcp.cc and tcp.h from http://netsrv.csc.ncsu.edu/twiki/bin/view/Main/BIC.html and compile it to my NS 2.26 i made a tcl file which was using that tcp.cc and tcp.h...but somehow the result didn't match with the theory because the 'congestion window' always changes to 1 every decreasing... i dont know if i made a wrong setting to my tcl file or not... could u please help me resolve this... thank you so much for your help.. Regards, Cinthia

[ns] IEEE 802.11g parameter and Extended MAC Model
Dear ns2 users, I'm using ns2 to perform wired-cum-wireless simulations. As regards the wireless channel+MAC model, I do not understand the real differences between the traditional IEEE 802.11 MAC model and the Ext one. I've checked the ns2 documentation to discover that the Ext one is just a refactoring of the previous model with additional fading techniques. Is this correct? If not, can you briefly explain me the principal differences between these two models? If any, which model is more accurate? In addition, I need the simulation parameters for the IEEE 802.11g model. I've found some solutions (http://hpds.ee.ncku.edu.tw/~smallko/ns2/11b.htm, http://blog.chinaunix.net/u/21684/showart_1076725.html), but I'm not sure that they consider all the necessary parameters. Can you confirm me that the parameters considered in the previous links are enough to simulate a correct IEEE 802.11 channel? Thank you for your attention.

[ns] NS2 installation problem
I have installed NS2 but NAM and xgraph do not work and when I done the validate this is what appeared validate overall report: some tests failed: ./test-all-simple ./test-all-tcp ./test-all-testReno ./test-all-newreno ./test-all-sack ./test-all-tcpOptions ./test-all-tcpReset ./test-all-simple-full ./test-all-full ./test-all-testReno-full ./test-all-testReno-bayfull ./test-all-sack-full ./test-all-tcp-init-win ./test-all-tcpVariants ./test-all-LimTransmit ./test-all-aimd ./test-all-greis ./test-all-rfc793edu ./test-all-rfc2581 ./test-all-rbp ./test-all-sctp ./test-all-tcpHighspeed ./test-all-frto ./test-all-friendly ./test-all-srm ./test-all-realaudio ./test-all-ecn ./test-all-ecn-ack ./test-all-ecn-full ./test-all-quickstart ./test-all-diffusion3 ./test-all-smac ./test-all-smac-multihop ./test-all-manual-routing ./test-all-hier-routing ./test-all-algo-routing ./test-all-lan ./test-all-mcast ./test-all-vc ./test-all-session ./test-all-mixmode ./test-all-red ./test-all-adaptive-red ./test-all-red-pd ./test-all-rio ./test-all-vq ./test-all-rem ./test-all-gk ./test-all-pi ./test-all-cbq ./test-all-schedule ./test-all-rr ./test-all-monitor ./test-all-jobs ./test-all-intserv ./test-all-diffserv ./test-all-webcache ./test-all-mcache ./test-all-webtraf ./test-all-mip ./test-all-links ./test-all-plm ./test-all-linkstate ./test-all-mpls ./test-all-oddBehaviors ./test-all-wireless-shadowing ./test-all-wireless-lan-aodv ./test-all-wireless-tdma ./test-all-wireless-gridkeeper ./test-all-wireless-diffusion ./test-all-wireless-lan-newnode ./test-all-satellite ./test-all-WLtutorial ./test-all-energy ./test-all-source-routing ./test-all-snoop ./test-all-misc ./test-all-tagged-trace ./test-all-message ./test-all-rng ./test-all-xcp ./test-all-wpan to re-run a specific test, cd tcl/test; ./test-all-TEST-NAME Notice that some tests in webcache will fail on freebsd when -O is turned on. This is due to some event reordering, which will disappear when -g is turned on. what should I do to solve this problem Thanks
