[ns] help for cross-layer design
Hi NS-uses, Can someone tell me where the pbject reference are returned by the folling statements TclObject* create(int, const char*const*) { return (new WirelessPhy); } I have seen in NS code the Ns-programmer has used the reference to the objects created by the following code this is AODV:command function else if (strcmp(argv[1], port-dmux) == 0) { dmux_ = (PortClassifier *)TclObject::lookup(argv[2]); if (dmux_ == 0) { fprintf (stderr, %s: %s lookup of %s failed\n, __FILE__, argv[1], argv[2]); return TCL_ERROR; } } By this above code, NS-programmer is getting pointer to the PortClassifier object from precompiled hirearchy, so that subsequently he can use it in AODV I want to understand how this is done, because I want to get reference of WirelessPhy object in AODV for cross layer work.. Any suggestion on this is very helpful Thanks you all Mallapur Veerayya M.Tech(CE) student Reg No. 06307416 IIT BOMBAY

[ns] Pls read!!!
For QoS routing, to determine the shortest path each link is assigned a weight and the shortest path is the one with the smallest aggregate weight. My questions is, how can I assign a weight value to a link?
[ns] regarding Multi-InteRfAce Cross-Layer Extension library for the Network Simulator
hi i searched the internet and i find Multi-InteRfAce Cross-Layer Extension library for the Network Simulator. its written on there website that In this release, in addition to MIRACLE library, it is included a set of libraries to simulate wireless system networks, in detail: Traffic generators TCP Agents IP modules IEEE802.11 (both the one from standard ns distribution and Multirate) MPhy, a general physical layer module in which interference of in-flight packets is evaluated using a Gaussian Model, and an enhanced propagation model is provided (fading with Jakes Simulator, shadowing with Gudmonson model and path loss with Hata model) UMTS: Link layer is derived from eurane extension [3] Physical layer is develpoed exteding Mphy Link and Wireless Channel physical mobility models (standard and Gauss Markov mobility model) i wann know anybody used umts in this extension.. i got really bad experience with eurane patch for umts.. please share if you got any info. thanks in advance
Re: [ns] 802.15.4 Modules
Il giorno lun, 17/09/2007 alle 10.17 -0500, Cristiane Amaral ha scritto: I am new to this list and want to know if there are any 802.15.4 modules for NS2 available? All the ns-2 versions newer than 2.28 contain 802.15.4 implementation. Versions newer than 2.31 contain several changes and bug fix respect to original release. Probably there are others bugs to be fixed. Please take a look to ns-2.xx/wpan for source code and to ns/tcl/ex/wpan for some example scenarios. You can find useful materials on this site: http://www.ee.washington.edu/research/funlab/802_15_4/ Regards Stefano.
[ns] G.711 codec

[ns] recv() not called for wirless agent, ns-2.31
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi NS-users, I just started coding my first agent (for ns 2.31) which works fine in wired scenarios. Since I want to send packets at some fixed times I call $ns_ at $time $node($i) send in my tcl script to send my packets. This works as expected and mentioned above in wired scenarios but not in wireless scenerios. The function command() is called but the packet never occurs in the tracefiles and recv() is never called. I already searched the web and looked in some sourcecodes but did not find an answer. So I am happy for a hint or maybe even a solution which helps me to fix my problem. If necessary I can post my sourcecode and/or tcl scripts.
