How To Perform Handoff In Mobile Node Fhmip

Hi all,

I tried to perfrom handoff of MN from previous access router(PAR) to new access router(NAR) when mobile node moves.
here i attched my output snapshot. In that MN (mobile node) connected to PAR initally, when it moves by crossing NAR the packets get dropped and handoff does not happen. but until MN was connected to PAR there was no loss.

Pls help me to get rid of this packet loss

Hi all,
I am using ns2 for my Master project and I want the pointer to current mobile node in mac802_11.
Can anyone help me?
Thanks in advance.

Hey guys
I have been trying to patch GPSR with ns-2.34.The operating system i am using is ubuntu 12.04.
I have made all the necessary changes required in the various files .

I have another version of ns (ns-2.35 ) too but it is in a different directory.
Everytime I run my tcl file an error keeps coming up.
I will be greatful if somebody can help me.This is very very URGENT.

Hi,
I have patched GPSR to ns-2.35 using keliu' code. It works fine with given tcl file. I need to move nodes according to mine own mobility scenario and compare them to AODV protocol.
I have two problems
1. I don't understand what this command in gpsr.tcl file means Code:

proc gpsr-create-mobile-node { id args } {
         .........................	
if [info exists opt(energy)] {
	$node addenergymodel [new $opt(energy) $node 10 0.5 0.2]}
         .............

What are these figures (0.5, 0.2), are these energy consumed in reception and transmission or some thing else.

Secondly I want move mobile node created using proc defined in gpsr.tcl file according to my own mobility plan e.g. Code:

 $ns_ at 0.000000000000 "$node_(0) setdest 144.816950690450 20.073824649527 0.324133202939"
$ns_ at 0.000000000000 "$node_(1) setdest 93.957720171475 192.140808646867 1.452613500562"
$ns_ at 12.158688172971 "$node_(23) setdest 113.137798368154 39.443538618334 0.902003496971"

But when I run simulation it gives error like this:[QUOTE]Load complete...
Starting Simulation...

Urgent help is needed please

Hi,

I intend to use mannasim script generator tool to create mobile nodes for routing protocols like aodv, leach , dsdv and dsr.

To be best of my knowledge, WSN nodes in mannasim are assumed to be static but I would like to know if there is a resource available which explains how the tcl code can be modified to achieve node mobility.

I have tried searching google but I haven't gotten satisfying search result.

It seems is better to ask an experienced ns2/mannasim user.

Be sure your kind response is valued

If you're here for the very first time, and have a very
urgent problem I appreciate that you're quite likely to
have other things on your mind than reading on.

However, if you do take the time to read all that's
said here (and follow the links) you're more likely
to get helpful responses! :)


The following two posts from Linux-General are just as
valid here in Linux-Newbie as they are there.

Hi everybody,
I need help!
I wrote a script in which, a mobile node across the umts, the WIMAX and the WIFI coverage to test the vertical handover .
But the out.nam file and the trace one are always empty, the script is correct there is no errors !!!!
please help

hello there!
the common communication between nodes is fine, but when i want to test the perimeter mode it has throw the error "Wrong the other node", it seems that it couldn't find its next hop node.
i trace the code as show below
Code:

int
GPSRNeighbors::intersect(nsaddr_t theother, double sx, double sy,
			 double dx, double dy){
  //line 1 (x1,y1)--(x2,y2) is the segment
  //line 2 (x3,y3)--(x4,y4) is the xD 
  struct gpsr_neighbor *other = getnb(theother);

  if(other==NULL){
    printf("Wrong the other node\n");
    exit(1);
  }


  ****************

struct gpsr_neighbor*
GPSRNeighbors::getnb(nsaddr_t nid){
  struct gpsr_neighbor *temp = head_;
  while(temp){
    if(temp->id_ == nid){
      if((GPSR_CURRENT - temp->ts_) < DEFAULT_GPSR_TIMEOUT)
	return temp;
      else {
	delnb(temp); //if this entry expire, delete it and return NULL
	return NULL;
      }
      return temp;
    }
    temp = temp->next_;
  }
  return NULL;
}

the simulation scene was shown in the attachment.
when i make node 0 send packet to node 1, the error will occur.
would somebody know how to solve it?
thank you for your time!

Hello, I started to use ns2.35 recently with Cygwin Terminal 1.7.35 under a virtual machine Windows XP Pro Service Pack 3. I'm having a problem when trying to apply a EDCA patch of 802.11e.

First i tried the oficial patch (intended for ns2.28), then i found a later version of EDCA:
Ref. post #18 he http://www.linuxquestions.org/questi...245/page2.html

I also tried to apply the patch for ns-2.35
Ref. post #70 he http://www.linuxquestions.org/questi...928/page5.html


After I made the changes in the files and running the following commands (as said by the 'README.txt' inside the patch)
./configure; make clean; make depend; make

I got the message:

Also, the ns command (which was working before the patch) now shows me an error:
Code:

bash: ns: command not found

I've searched the ns directory and the ns executable there is no more.


Do you have any ideia how to correct this?

Thank you in advance.

Hi everyone..i have problem in running Mobile Cloud Gaming using NS2. Can anyone share simple coding on Mobile Cloud Gaming using NS2
