[ns] How to get the Nodes' coordinate from TCL to C++
Dear NS Users, Can someone please tell me how you can retrieve the coordinates of the network nodes from a TCL file into C++. So is their some loop or something that can be written in C++ and traverses all the nodes and gets X, Y, Z, and how is it written. Hope you can help me. Thanks, Mathiew
[ns] NAM don't update the mobile node movement's starting position
Hi I am using NAM to show the mobile node movement in ns2.33. NAM is showing the moving nodes, but another initial image of the node is also kept in the screen. can anybody tell me why? and some of the nodes are sometimes shown in ash color, not in the default color black. If you know why and how can I solve it, please let me know. attached is a snapshot of nam. link - http://folk.ntnu.no/ashraful/file/ns/nam-screen.jpg brmany many thanks in advance. - Ashraf
Re: [ns] Setting tcl script variables from inside C++ code
Hello Fernando, You can use the following code: Tcl tcl = Tcl::instance(); sprintf(tcl.buffer(), set my_tcl_var %f, 10.123); tcl.eval(); Note that you can use the same method to execute any command on Tcl. You can find more information in chapter 3 of the ns-manual. Good luck Waleed On Tue, Jan 20, 2009 at 3:09 PM, fh...@c3sl.ufpr.br wrote: Well, it is just as the title says: I would like to know how to change the value of my tcl script variables from inside my C++ code.

Re: [ns] How to get the Nodes' coordinate from TCL to C++
Hello Walid, Thanks for the reply. You said getting the coordinates from the TCL file easier... i have them stored in a topography.tcl file (or so i recall) that has the X Y Z coordinates of each sensor. So what's the way to get them from the TCL file directly to be used in C++ ?? Thanks alot, Mathiew Quoting Waleed Tuffaha tuff...@gmail.com: Hello Mathiew, ( Note that I didn't test this ! ) The Node class uses a Location class in which the X,Y,Z variables are defined. The mobilenode class inherits from the node class. So, if node_ is a pointer to a mobilenode, then you should be able to get the coordinates using: int x,y,z; node_-location_-getLocation(x, y, z) So if you have an array containing pointers to all the nodes then you can loop on the array and get the coordinates for each node. I think that getting the coordinates from Tcl is easier, but I don't know what exactly you are doing. Hope this helps -- Waleed On Thu, Jan 22, 2009 at 9:59 AM, Mathiew Moussa mm...@aub.edu.lb wrote: Dear NS Users, Can someone please tell me how you can retrieve the coordinates of the network nodes from a TCL file into C++.

Re: [ns] How to determine txpower from Pt_
Hello Manish, My understanding is that the two parameters are not related. Pt_ defines the amount of power transmitted from the antenna (Phy/WirelessPhy), and thus; it defines (together with the RXThresh_ parameter) the range of the mobile-node. And it is not used by the energy model. txpower defines how much power a mobile-node, as a whole, consumes when it is transmitting, and it is the one used by the energy model. For example; the PRO/Wireless 3945ABG card on my laptop can consume a maximum power of 1.8 Watt while transmitting and a maximum of 1.4 Watt while receiving. But the maximum transmitting power is 15 dBm ( ~ 31 mW) ! -- Waleed Tuffaha On Wed, Jan 21, 2009 at 7:07 AM, manish chaturvedi msc@gmail.comwrote: Hi, I am trying to incorporate energy model in my NS2.33 simulation. I have some confusion between Pt_(used to set transmission range), and txpower(energy model parameter specifying enegy consumption in transmission). I need to know what is the relation between these values, and how can I calculate one(txpower) given the other(Pt_). I looked at some old discussions on this mailing list but could not make it from there. Please give information or point to some source of this information. Thanking you,Manish.
[ns] NS transmission powers based in tinyOS
In the protocol that I am currently implementing on NS2 the transmission powers does vary a lot. Its initial implemention was done in tinyOS, and that is why I need to simulate its available transmission powers. There is a range of 255 possible ones in tinyOS, and I would like to change the NS variables (Pt_ [Transmit Power], CPThresh_ [Collision Threshold], CSThresh_ [Carrier Sense Power], RXThresh_ [Receive Power Threshold]), so an approximate behavior could be simulated. I do know the power consumption in mA and the Pout in dBm for each one of these 255 possible powers. Is there be any possible way to set the NS variables so that I would manage to reach an approximate behavior to tinyOS? Thanks in advance, -- Fernando Henrique Gielow - UFPR - NR2 Computer Science graduation student.
[ns] How to generate energy traces periodically
Hi, I am using energy model in my NS simulation. When energy trace is ON, every time the node energy changes, the trace is generated. This makes trace file size larger. Is there any way to generate trace of energy status of all nodes at some fixed time or periodically? Please inform or point me to some source of information. Thanking you, Manish
