[ns] Fwd: Need paper : interconnect optimization using ns2
Hi Friends, I need these three papers related to NS2, but I dont have access to them. If someone is having these papers then please send me. http://ieeexplore.ieee.org/Xplore/login.jsp?url=http%3A%2F%2Fieeexplore.ieee.org%2Fiel5%2F5445099%2F5451200%2F05451835.pdf%3Farnumber%3D5451835authDecision=-202 http://ieeexplore.ieee.org/Xplore/login.jsp?url=http%3A%2F%2Fieeexplore.ieee.org%2Fiel5%2F5487987%2F5489106%2F05489490.pdf%3Farnumber%3D5489490authDecision=-202 http://ieeexplore.ieee.org/Xplore/login.jsp?url=http%3A%2F%2Fieeexplore.ieee.org%2Fiel5%2F5487987%2F5489106%2F05489498.pdf%3Farnumber%3D5489498authDecision=-202 Thanks Regards, Udit Kumar
Re: [ns] How to parse wireless trace files..
Hi all, I need to parse wireless trace files. Please either send an .awk file or suggest a way to parse wireless trace files. Explanation given in ns manual has been of little help. Thanks in advance. -- Shaktijeet Mahapatra
[ns] How to access node ID in TCP model?
Hi, I'm working on TCP models and I'm edition tcp.cc andd tcp.h files. what I want to know, how do I access the node by its Id as I'm assigning in tcl for each node a number (as you all know). I tries to create an object from Node and access the variable nodeid_, however the returned value was 0 which means that it creates new id. Help or suggestion on this issue is highly appreciated.

[ns] what does it means ???
Dear all , Please ca n someone explain me this error in NS2 -- Classfier::no-slot{} default handler (tcl/lib/ns-lib.tcl) --- _o270: no target for slot 3 _o270 type: Classifier/Addr content dump: classifier _o270 0 offset 22 shift 1023 mask 1 slots slot 5: _o271 (Classifier/Addr) -- Finished standard no-slot{} default handler -- I can't find the object _o270 and _o271 so i can't understand where is the fault ??? I noted that I receive this error only when i have more then 2 mobile nodes. Best regards El hadi

Re: [ns] what does it means ???
Hi, The no-slot error occurs since you did not configure the classifier properly. In particular, you ask NS2 to send a packet to a non-existing object. For more information, please read the following post: http://www.ns2ultimate.com/post/520626807/classifier-no-slot-error Best Wishes, Teerawat Issariyakul http://www.ns2ultimate.com/ http://www.facebook.com/pages/Teerawat-Issariyakul/358240861417 http://twitter.com/T_Bear http://www.t-issariyakul.blogspot.com http://www.ece.ubc.ca/~teerawat On 12/12/2010, El hadi Cherkaoui e_cherka...@yahoo.fr wrote: Dear all , Please ca n someone explain me this error in NS2 -- Classfier::no-slot{} default handler (tcl/lib/ns-lib.tcl) --- _o270: no target for slot 3 _o270 type: Classifier/Addr content dump: classifier _o270 0 offset 22 shift 1023 mask 1 slots slot 5: _o271 (Classifier/Addr) -- Finished standard no-slot{} default handler -- I can't find the object _o270 and _o271 so i can't understand where is the fault ???

[ns] Why caculationof distCST_ changed in wirelessPhyExt (ns2.34)
Hi, I am still confused on the carrier sense threshold. 1. CS_thresh CS_thresh is too large by default value (6.31e-12, 802.11a), the corresponding range is 168.3m , which equals to transmission range. 2. distCST_ is the carrier sensing range , but it is caculated according to powermonitorthresh, ( )as in channel.cc: Phy/WirelessPhyExt set PowerMonitorThresh_ 1.259e-13 distCST_ = 447 m if (dynamic_castWirelessPhyExt*(tifp)) { WirelessPhyExt *wifp = (WirelessPhyExt *)tifp; distCST_ = wifp-getDist(wifp-getPowerMonitorThresh(), wifp-getPt(), wifp-getAntennaRxGain(), wifp-getAntennaTxGain(), highestZ , highestZ, wifp-getL(), wifp-getLambda());
Re: [ns] sleep node in WPAN
Hi all, I want to make set of nodes to be active and others in sleep state. I added following codes to node configuration: -initialEnergy 1 \ -rxPower 0.3 \ -txPower 0.3 \ -set_node_sleep 1 \ but this code makes all nodes enter into sleep mode after initial energy has gone. What should i add to make particular nodes to sleep? Thanks in advance. -- Regards, Subha
