For more infoabout this command (part of new node APIs) see chapter titled "Restructuringns node and new Node APIs" in ns Notes and Documentation.<P><DIV ALIGN="LEFT"><TT>$ns_ node optional:hier address</TT><BR>This command is used to create a mobilenode after node configuration is doneas shown in the node-config command. Incase hierarchical addressing is beingused, the hier address of the node needs to be passed as well.</DIV><P><DIV ALIGN="LEFT"><TT>$node log-movement</TT><BR>This command previously used to enable logging of mobilenode's movement has nowbeen replaced by <TT>$ns_ node-config -movementTrace ON or OFF</TT>.</DIV><P><DIV ALIGN="LEFT"><TT>create-god num_nodes</TT><BR>This command is used to create a God instance. The number of mobilenodesis passed as argument which is used by God to create a matrix to storeconnectivity information of the topology.</DIV><P><DIV ALIGN="LEFT"><TT>$topo load_flatgrid X Y optional:res</TT><BR>This initializes the grid for the topography object. <X> and <Y> are the x-yco-ordinates for the topology and are used for sizing the grid. The gridresolution may be passed as <res>. A default value of 1 is normally used.</DIV><P><DIV ALIGN="LEFT"><TT>$topo load_demfile file-descrptor</TT><BR>For loading DEMFile objects into topography. See /dem.cc,.h for details onDEMFiles.</DIV><P><DIV ALIGN="LEFT"><TT>$ns_ namtrace-all-wireless namtrace X Y</TT><BR>This command is used to initialize a namtrace file for logging node movementsto be viewed in nam. The namtrace file descriptor, the X and Y co-ordinates of the wireless topology is passed as parameters withthis command.</DIV><P><DIV ALIGN="LEFT"><TT>$ns_ nam-end-wireless stop-time</TT><BR>This command is used to tell nam the simulation stop time given by <stop-time>.</DIV><P><DIV ALIGN="LEFT"><TT>$ns_ initial_node_pos node size</TT><BR>This command defines the node initial position in nam. <size> denotes the sizeof node in nam. This function must be called after mobility model has beendefined.</DIV><P><DIV ALIGN="LEFT"><TT>$mobilenode random-motion 0 or 1</TT><BR>Random-motion is used to turn on random movements for the mobilenode, in whichcase random destinations are assigned to the node. 0 disables and 1 enablesrandom-motion.</DIV><P><DIV ALIGN="LEFT"><TT>$mobilenode setdest X Y s</TT><BR>This command is used to setup a destination for the mobilenode. The mobilenode starts moving towards destination given by <X> and <Y> at a speed of<s> m/s.</DIV><P><DIV ALIGN="LEFT"><TT>$mobilenode reset</TT><BR>This command is used to reset all the objects in the nodes (network components like LL, MAC, phy etc).</DIV><P><DIV ALIGN="LEFT">Internal procedures<BR>Following is a list of internal procedures used in wireless networking:</DIV><P><DIV ALIGN="LEFT"><TT>$mobilenode base-station BSnode-hier-addr</TT><BR>This is used for wired-cum-wireless scenarios. Here the mobilenode is providedwith the base-stationnode info for its domain. The address is hierarchicalsince wired-cum-wireless scenarios typically use hierarchical addressing.</DIV><P><DIV ALIGN="LEFT"><TT>$mobilenode log-target target-object</TT><BR>The <target-object>, which is normally a trace object, is used to logmobilenode movements and their energy usage, if energy model is provided.</DIV><P><DIV ALIGN="LEFT"><TT>$mobilenode topography topoinstance</TT><BR>This command is used to provide the node with a handle to the topographyobject.</DIV><P><DIV ALIGN="LEFT"><TT>$mobilenode addif</TT><BR>A mobilenode may have more than one network interface. This command is usedto pass handle for a network interface to the node.</DIV><P><DIV ALIGN="LEFT"><TT>$mobilenode namattach namtracefd</TT><BR>This command is used to attach the namtrace file descriptor <namtracefd>to the mobilenode. All nam traces for the node are then written into thisnamtrace file.</DIV><P><DIV ALIGN="LEFT"><TT>$mobilenode radius r</TT><BR>The radius <r> denotes the node's range. All mobilenodes that fall withinthe circle of radius <r> with the node at its center are considered asneighbours. This info is typically used by the gridkeeper.</DIV><P><DIV ALIGN="LEFT"><TT>$mobilenode start</TT><BR>This command is used to start off the movement of the mobilenode.</DIV><P><DIV ALIGN="LEFT"></DIV><HR><!--Navigation Panel--><A NAME="tex2html4249" HREF="node195.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node195.html"><IMG WIDTH="37" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="next" SRC="file:/usr/share/latex2html/icons/next.png"></A> <A NAME="tex2html4243" HREF="node171.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node171.html"><IMG WIDTH="26" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="up" SRC="file:/usr/share/latex2html/icons/up.png"></A> <A NAME="tex2html4239" HREF="node193.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node193.html"><IMG WIDTH="63" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="previous" SRC="file:/usr/share/latex2html/icons/prev.png"></A> <A NAME="tex2html4245" HREF="node1.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node1.html"><IMG WIDTH="65" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="contents" SRC="file:/usr/share/latex2html/icons/contents.png"></A> <A NAME="tex2html4247" HREF="node590.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node590.html"><IMG WIDTH="43" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="index" SRC="file:/usr/share/latex2html/icons/index.png"></A> <BR><B> Next:</B> <A NAME="tex2html4250" HREF="node195.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node195.html">17.
