[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,

[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

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,

Hi Samar asf, You can use the following code to run a simple example of aodv. # A 3-node example for ad-hoc simulation with AODV # Define options set val(chan) Channel/WirelessChannel;#

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

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

[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

[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
