[ns] To know free buffer space available
Hello... Am doing my final year project in NS2 are there any commands to know about the free buffer space available in routers.. please do help.. thanks..

[ns] How i can use Obstcale model with Hybrid model(Manhattan and RWP models) for node movement in urban area
Hi ALL i have simulated (DSR,AODV,DSDV)using hybrid model (Manhattan and Random Waypoint).I want to check the performance of these adhoc protocols in real environment(urban area or in campus environment). i looked for added obstacle mobility model to manhattan and Random waypoint for more realistic work. thanks for any suggestion with regards ibrahim khider - Be a PS3 game guru.

Re: [ns] new wireless trace format
Hi list, Try as I might, I can't get my wireless traces to spit out in new format. I'm using nsclick (compiled with ns2 version 2.3) and it seems to otherwise be performing fine. However, when I try the well-documented: set ns_ [new Simulator] set tracefd [open "" w] $ns_ use-newtrace $ns_ trace-all $tracefd The output resolutely comes out in old format. I've also tried setting: Simulator set WirelessNewTrace_ 1 (as seems to be in the ns-lib.tcl) And Simulator set newTraceFormat_ 1 (as seems to be indicated in http://www.isi.edu/nsnam/ns/doc/node185.html) But no joy. Any suggestions would be very welcome. Best Regards, Dave Bath University of Bristol, UK
[ns] Tracegraph CANNOT BE TRUSTED in all simulation scenarios
hi all, I used Tracegraph to analyse trace file of ns-2. I found that it works good when there is no frequent packet drops and retransmission. In a simulation where a large packet drops and retransmission exist (for example in my case I used the shadowing model in the PHY layer and used a multihop scenario with up to 4 hops) Tracegraph fails to give a correct analysis results. I think that Tracegraph CANNOT BE TRUSTED in all simulation scenarios. One should check his results using another tool (do some sample checks with awk or perl or grep command) or do his own analysis code. Yours, Samer

Re: [ns] ns2 post-analysis of the trace files
I used ns2 simulator to create trace files in two formats from tdma simulation. 1) old wireless format 2) new wireless format I usually feed this to "tracegraph" to get my results and plot them. I have been looking for custom AWK/PERL scripts to write those analysis myself. In the old wireless format , with some simple counts and pattern matching, i can find the generated packets, dropped packets and bytes, forwarded packets and bytes. But sent packets: i couldnt find anyway that matches with the output from the tracegraph file. And when i run the same scripts for the new wireless format .. [ i mean the idea same with counts ] , most of the parameters differ. Basically, i have to come up with scripts to calculate average delay, variation in delays (or jitter), throughput in bits per seconds, packets generated/sent/forwarded/dropped. Is there any available scripts already, or any documentation that can lead me to find the exact definition of how to calculate these.[ in the new wireless format ]. I tried this link http://mailman.isi.edu/pipermail/ns-users/2004-September/044669.html from the archives, but no luck. Thanks
[ns] Undefined reference to MobiCache::~MobiCache()...
Hello I have made some modifications to the dsr protocol. After that I tried to 'make' so that the changes can take effect. But after creation of so many .o files, it showed me errors like: Undefined refernce to MobiCache::MobiCache() They are many with different functions. What should be the problem with that? What shall I do to solve it? Please get me a faster solution to this. Thanks Netsanet Food fight? Enjoy some healthy debate in the Yahoo!
