[ns] URGENT HELP >> object tracking with wireless sensor networks in NS 2 !!!

Hi all, I want to simulate a sensor network for example with 10 sesnors and an object passing between them, sensors should sense the object and track it and tell the base station, but i cant find any help file with examples of such simulations !!! how to simulate such networs in NS2 ?? if y

[ns] R: why setdest so slow?

Guanhua, are you referring to the generation of the mobility traces or to the simulation of the network itself? In the first case that's very strange, in the second case it could be due to the fact that the default ns-2 scheduler is very slow in allocating events far in time. My advice is to

[ns] R: looking for"hcf" implementation

If you are referring to 802.11e HCF, you can find a couple of implementations at: http://info.iet.unipi.it/~cng/ns2hcca/ http://www- sop.inria.fr/planete/qni/Research.html Next time be more specific in your question and search the web or the ns-2 site for the information you are looking for,

[ns] a comparison between the wireless routing protocols

Hello ns users! I,m working with ns 2.29 in Mandriva 2006 and i need to make a comparison between the existing wireless routing protocols(DSDV, AODV, DSR...). I thought about creating Xgraph files that would show the traffic, delay, speed...,but i don't know what topologies to use to be relev

Re: [ns] a comparison between the wireless routing protocols

To follow up on this: Make a simulation plan first. What do I mean by that? I mean that, before you implement anything, think about WHAT you want to test and how you could show that. I am currently attending a lecture on simulation and our professor really stressed that most people doing compu

Re: [ns] Newbie questions on wpan demo

Hi Bruce, Read chapeter 13 in ns-manual.. I think you are looking for Error Model instead of Loss Model. The commands you are using are for wired networks only, if I am not mistaken. Bruce Who wrote: >hi, Ahmad: > >=== 2006-04-03 02:05:24 Ahmad Khayyat wrote: === > > > >>Hi Bruce, >>

[ns] mobilenode object gets messed up

Hi all, I am working with the mobilenode class of ns-2.29. At the beginning of my simulation the mobile node objects hold proper values for X_, Y_ coordinates, amongst others. But after the "SORTING LISTS" when the Pr() function of the propagation model is called, all the mobilenode objects only

Hi everyone, does anybody know if and where the DataRate at which packets are transmitted on a wireless channel is recorded in some header? Thanks, Marco Fiore

[ns] Anyone recognise this error msg?

I have a number of scripts that are all failing with exactly the same error msg (see below). It appears to be something to do with starting a server for a group. Im using MDP (Multicast Dissemination Protocol), does anyone else have experience with MDP out of interest. The files that are failin

[ns] urgent help reg energy model in ns

HI, I have used the energy model in my tcl file and have specified initial energy to be 200.. according to cmu-trace.cc file the mobile node must become green.. in my nam it has become green.. however wen the energy gets depleted or reaches zero ,the color of the node must change acc to cmu-trace.

Re: [ns] Newbie questions on wpan demo

Hi, I got it. Page 127 of ns-doc.pdf tells us how to do it. But it's really hard to find it. I thought it is covered in "Chapter 16 Mobile Networking in ns" or "Chapter 6 Links: Simple Links" Another question, How long does it take to transmit a packet? I found this snippet in ns/tcl/ex/wpan:

[ns] energy model in ns

HI, I find that in the energy model the energy is getting reduced(in receive and transmit mode) only for MAC,RTS,CTS etc. packets and not for TCP packets.. I need to find out how much energy is consumed for the transmission and reception of TCP packets and also the amount of time spent in the 'sle
