[ns] problem about Ns by Example
Hi, i am a beginner for ns user, my NS version is all-in-one-2.29,when i try to do as the step in the add new application and agentpart in Ns by Example,say,add the mmapp. there are trouble when i add the default value in ns-default.tcl.couldanyone tell me the reason,I really appreciate your help. when i add the default value as the ns by example Application/Mmapp set rate0_ 0.3mb Application/Mmapp set rate1_ 0.6mb Application/Mmapp set rate2_ 0.9mb Application/Mmapp set rate3_ 1.2mb Application/Mmapp set rate4_ 1.5mb Application/Mmapp set pktsize_ 1000 Application/Mmapp set random_ false the result is following: ns: [code omitted because of length] : invalid command name Application/Mmapp while executing Application/Mmapp set rate0_ 0.3mb when i using # omit the default value. the run result is as following: ns ex-mm-app.tcl warning: no class variable Application/MmApp::rate0_ see tcl-object.tcl in tclcl for info about this warning. warning: no class variable Application/MmApp::rate1_ warning: no class variable Application/MmApp::rate2_ warning: no class variable Application/MmApp::rate3_ warning: no class variable Application/MmApp::rate4_ warning: no class variable Application/MmApp::pktsize_ warning: no class variable Application/MmApp::random_ warning: no class variable Application/MmApp::rate0_ see tcl-object.tcl in tclcl for info about this warning. warning: no class variable Application/MmApp::rate1_ warning: no class variable Application/MmApp::rate2_ warning: no class variable Application/MmApp::rate3_ warning: no class variable Application/MmApp::rate4_ warning: no class variable Application/MmApp::pktsize_ warning: no class variable Application/MmApp::random_

[ns] Simulate an End System Multicast protocol (Narada) - where to begin?
Hi all, I'm new to NS now. My group tries to simulate the Narada protocol - an End system multicast protocol which works on the application layer. I wonder where I could begin? I think that with End system multicast architecture, we need not to develop a new underlying protocol, we just need to implement the overlay network and its application-level communication protocol only, with the underlying network protocol (TCP/IP) support. I think that we should derive a new Application in the ns class hierarchy. I'm not sure whether this is an accurate start point. Anyone can help? Thanks.
[ns] Broadcast packets and LL
Hi all! I would like to use Broadcast packets in a wired scenario. Is it possible? If I use IP_BRODCAST it seems not working (no target for slot -1). Is it working only for wireless networks? Why? Does the LL work with wired network? Because it seems that even when I build a newLan object (for example in lantest.tcl) it doesn't work. Please, help me, because it's really important for my thesis degree! Have a nice day, Paolo

[ns] AODV - writing into trace file
Hi altogether, i have a minor problem which evolves to a bigger problem for me. I need to write a line into the AODV trace file, when a node sends a data packet. The line should include the source id, the destination id and the pathlength (meaning the number of hops between source and destination). Then I had a look where AODV writes something into the trace file; I only found aodv_logs.*. But where does AODV writes a line into the trace when a node sends, receives and forwards a packet? Did I overlook something? I suppose so, but where? Thanks in advance for any help Robin Pomplun
