[ns] ns-2 help
Hi, ns-users Have anyone heard about the Alternate Path Routing there is a paper on this subject, originated by D. Zappala, Does anyone knowwhether this protocol has been implemented in ns2? If the answer is yes, where can I find the source code? Tks for the help. P.B.BHAVATHANKAR. M.Tech (COMPUTER) VJTI, MUMBAI __ Yahoo! India Answers: Share what you know.

[ns] MultiStateErrorModel and tcl calls
Greetings all, This is a question on MultiStateErrorModel. I see that the model's corrupt(Packet* p) function makes a tcl call for each packet. Unless I misunderstood chapter-3 of the manual, this is really supposed to slow down the simulation. Has anyone experienced slow performance with MultiStateErrorModel, or is there anything I am missing here? Cheers, Guray
[ns] warning on TwoStateErrorModel
Greetings, I just wanted to warn people who intend to use TwoStateErrorModel and its derivatives. Note that the transitionState() function of this class upperbounds the duration of state_1 with 120 seconds. This is done in errmodel.cc in ns v2.30. I do not know the reason behind this upperlimit, but if I am not mistaken, this upperbound makes it pointless to assign an average duration to state_1 at the time this class is instantiated. I would be happy to hear what others think. Regards, Guray

Re: [ns] installation script doesn't consider /usr/include/X11 for X11 headers
Hello Ahmad, Ahmad Khayyat wrote: > Try installing xorg-dev. > It will pull down a lot of X development dependencies. Thanks for the hint, that basically did the trick. I didn't want to cluster my machine with tons of possibly unnecessary dev-packages (xorg-dev is a meta-package), however, so I did some more digging into the (un-)successful configure outputs. It came to notice that apparently I was also missing a file called "Intrinsic.h" which is part of the `libxt-dev' package in Ubuntu. This package only pulled in another 3 dependent packages on my system. Still the whole issue is somewhat strange as I am able to compile ns-2 without "Intrinsic.h" by tweaking the install-script just a little bit. Don't know if this is the way it's supposed to be, but hey, at least it's working out-of-the-box now.

[ns] Sanity-check of energy consumption of 802.15.4 sensor nodes
Dear all, My question is actually a sanity-check of the energy consumption of IEEE 802.15.4 sensor nodes. I have a very simple simulation with a handful of wireless nodes employing IEEE 802.15.4 (ns2.29 code) and a wired sink. I have assumed 2AA batteries as the energy source, translating into 30.8 KJ for each sensor. There is no sleeping mode for the sensors, whenever they are not transmitting or receiving, they are in idle state. The transmission rate is 250 Kbps (@2.4GHz). If I run a simulation with 3 flows at 1 packet per second for a whole day (86.400 secs), the energy they are consuming is only around 250-300 J. Does this seem fairly reasonable to you? I was expecting their energy to be depleting much sooner since they are not using any sleeping schedule. Cheers, Athanasia PS. *other parameters I have used are: set opt(txpow) 0.0522 ;#calculated from P=VI with 17.4mA that corresponds to 0dBm TX power from MICAZ datasheet set opt(rxpow) 0.0591 ;# 19.7mA current drain set opt(idpow) 0.6;#20 \uA set opt(slpow) 0.03 ;# 1\uA -- Ms Athanasia Tsertou Research Associate Institute for Digital Communications School of Engineering and Electronics The University of Edinburgh Room 2.12, AGB Building, The Kings Buildings, Mayfield Road Edinburgh, EH9 3JL UK Tel:+44 (0)1316505659 Fax:+44 (0)1316506554 Email:[EMAIL PROTECTED]

If it is only the added files try adding them (make a backup of your working ns-allinone tree first). If it is a set of patches apply them. If it is the whole thing you probably need to get a reference copy of ns-2.1b and do your own diff to make a set of patches to apply.

Re: [ns] Doubts about MIPv4 simulation(wireless3.tcl)
Hi, 1.I am trying to understand March Greis tutorial(wireless3.tcl). When the MN moves within the HA area, there is a lot of dropped packets. The only line I modified is the setdest for MN. Why is this happening? (This is assuming that the default ranges for MN,HA and FA are 250m.) 2.Also where do we describe that some base_stn is the FA of a MN. We do set the FA with the hierarchical address in the program. But how does it realise that this heirarchical address is the FA. What if I want a lot of FA's. How do I simulate them? For HA we do an explicit definition but I dont see us doing this for FA. 3.When I use dsdv for routing protocol, a lot of packets are being dropped with base_stn unknown error. How do I avoid this error? I tried positioning the HA and FA so they are centers are 500m apart and give MN a straight line movement from the center of HA to the center of FA. Why are the packets still being dropped? Your help in understanding this implementation is greatly appreciated. Thank you in advance, Vidhya - Food fight? Enjoy some healthy debate in the Yahoo! Answers Food & Drink Q&A.

[ns] urgent: help regarding euran programming
hi i have some problem in euran programming. i tried the test script these run fine. but i want to modify umts script. (in which current communication between node1-rnc and acknowledgement send to bs which is at node1.) but there is no communication to ue1 or ue2 which are connected by umts link. when i try to connect rnc and ue1 through wireless channel or by duplex link this gives error. please advice me how to send data to ue from node1 through base station through umts .. and i try to join euran's mailing list and join that no of time but no reply received from this. can u please tell me how to join this. thanks in advance harpreet singh
Re: [ns] definition of sending / receiving threshold per mobile node
Hi Markus, Leitner, Markus schrieb: I am currently working on a project dealing with simulation of mobile nodes. To describe relevant network topologies I am searching for a possibility to define the receiving threshold individually per node (e.g. mobile node A has a receiving threshold of X, while all other nodes have a receiving threshold of Y). I know how to set the receiving threshold in principle via RXThresh_ but I unfortunately did not find any way of specifying this per node. Is anybody aware how to implement this? I don't know if the following works for the threshold (it did for the antenna gain). Just give it a try. Set the threshold before you create a node. The node constructor will copy the value and you can change it later without changing the properties of already existing nodes. Maybe this is a bug - but we used it as a feature. Daniel. -- Dr.-Ing.

Re: [ns] installation script doesn't consider /usr/include/X11 for X11 headers

If you mean by that I should install the missing X headers: Of course, I did that. I'm not blaming NS for not finding dependent software non-existing on my machine -- that'd be too much of a demand. :-) The fault IMHO is that although the X11 headers are installed on my machine ns-2 won't find them but claim there're not installed. I've looked at a bunch of configure scripts and Makefiles but none seemed to include the path mentioned in the subject line. Since Debian and Debian-based distros represent a rather big share of the Linux market, I'll file this as a bug unless someone else can hint me at some possible mistake of mine. --Timo
[ns] error while executing mwnode-ex.tcl

[ns] power aware routing in NS-2
hi all, I am implementing a power aware routing protocol for ad hoc networks in NS-2.The present energy model in NS-2 is not power aware..Does anyone know how to implement such a protocol in NS-2,and where to find the battery parameters for each node.
[ns] How to test a new protocol? [nsrt-howto]
Dear ns-users, I am trying to implement a new protocol for NS-2 following the howto "Implementing a New Manet Unicast Routing Protocol in NS2", which is available at http://masimum.dif.um.es/nsrt-howto/html/. After adding some missing header files, I could recompile NS with the new protocol, but I am not able to see the results. I defined a very simple scenario with 3 wireless nodes but I am not able to see the exchange of packets. However, with AODV or DSDV the tcl script works fine. I wonder if I should define a Protoname Agent (like in the example Ping of Marc Greis, but I get a segmentation fault, and I am not sure that it is really needed). If someone has any kind of tcl code or link to a scrip I would really appreciate the help. Best regards, Javi __ LLama Gratis a cualquier PC del Mundo.
