Re: [ns] How to specify "wait" in ns2
I think you can use the timer class of NS2 in c++. You can find how to use timer in most souce code, such as tcp.cc, tfrc.cc. - Original Message - From: "Heo Heo" <[EMAIL PROTECTED]> To: Sent: Monday, May 22, 2006 12:47 PM Subject: [ns] How to specify "wait" in ns2 > > I am working on improving AODV, and I need to specify "wait" in ns2, > something like: > > - When the routing packets (RREQ) arrive, just store it into a buffer > and do not send out anything. > > - Wait for a period of X miliseconds.

[ns] How to specify "wait" in ns2
I am working on improving AODV, and I need to specify "wait" in ns2, something like: - When the routing packets (RREQ) arrive, just store it into a buffer and do not send out anything. - Wait for a period of X miliseconds. After that, look into the buffer and select the routing packet that satisfy some conditions and send it out. I don't know how to do that "wait for X miliseconds". Thanks a lot for any help. - Feel free to call! Free PC-to-PC calls. Low rates on PC-to-Phone. Get Yahoo! Messenger with Voice
[ns] Validation Error
I installed ns-allinone 2.29 on ubuntu64 (6.06 beta). After validation, I got some validation error as follows : --- validate overall report: some tests failed: ./test-all-srm ./test-all-smac-multihop ./test-all-hier-routing ./test-all-algo-routing ./test-all-mcast ./test-all-vc ./test-all-session ./test-all-mixmode ./test-all-webcache ./test-all-mcache ./test-all-plm ./test-all-wireless-tdma ./test-all-energy 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. --- I guess that's because generation of random numbers of 64bit os differs from that of 32bit os. How can I solve this problem?

Re: [ns] Does anyone in this forum has detailed knowledge about the NS2source code?
Hi Paul, Thanks for the link. I totally agree with you. I have spent so much time trying to understand as to how does the simulation flows through the source code, but can't really make any headways anymore. I am trying to implement a new control flow mechanism where no packet are dropped, but in order to do so I have read the queue size of the next hop so that the current node can decide whether to accept any more packets from other nodes or flag its exception indicatiing to all other nodes feeding into it to stop sending more packets to it. I am really stuck right now because I can't locate where in the source code does the current node find its next hop address and how does it find that out. I have bunch of more questions like how does the node and agents are located to each other because nodes don't store any information regarding agents or classifiers within them and vice-versa. I am still waiting if someone could lend some insight into it. Please let me know if you have any comments or if you find any help.

[ns] ns remove() error
Hello, I searched for this error online, and it's happened before, but I couldn't find an explanation for why: in my wireless model, I've been decreasing the distance between nodes. If I make the nodes too close, I get this error after ns runs for ~1.8 simulation seconds: PacketQueue:: remove() couldn't find target and then it quits. Can anyone tell me why the distance between nodes matters? What is ns-2 even complaining about? I went to this error in queue/queue.cc and couldn't tell what the function was doing. Thanks, Kathy
[ns] TFRC simulation in NS-2
Hello, I am trying to see how TFRC and TCP (Reno) share the same bottleneck linkt. I have prepared the script but I cant see any fairness in the throughput ;) Do you happen to know how to configure TFRC in NS 2.29 to behave in a friendly way towards TCP? Could anyone send me tcl script for it ? I would also appreciate to see the perl or awk script to measure throughput from trace files. Thanks for your help -- Regards, Kacper Kurowski

Hi, I am really curious to know if anybody in this forum has detailed knowledge about the network simulator source code. I have a lot of questions and I have tried posting it here but haven't received any responses with people who are the architects of the source code. I really want to know once the node is created through node.cc, is that node referenced anywhere else in the source code? I tried to step through each step of the source code and could not find any reference to it. In the document, it says that classifiers are associated with each node. Is there any ways of accessing these classifier from the node itelf? I mean from the static node list created from node.cc. Is it possible to access queues associated with each classifier (link)? The variable target_ is used all over the source code without providing any satisfactory explanation for its usage in various places. What does target_ really means? Does it means the next hop node for the packet? If thats the case then why it's address doesn't match with the address of one of the nodes from the static node list created initially from node.cc? If someone here knows the inside out of the simulator, please comment on the above questions. Thanks, - Faisal
