How To Do Handoff In Fhmip Patched At Ns2.33

hi ,

i followed the post and get patched fhmip and run ns fhmip_simula.tcl

http://www.linuxquestions.org/questi...gz-4175538523/

when i moved mobile node hand off not occured, only i am getting packet loss.

an ideas??

Thanks
Pon

I have several computers connected to a D-Link DIR605L router, two with ethernet cables and two through wifi. The Windows XP computer can see itself and nobody else. The Ubuntu (trusty) desktop and Ubuntu (lucid) netbook computers see nobody (unable to retrieve file list from server) and the Windows Vista computer only sees itself. Clearly, I have failed to configure something or a set of somethings.
Do I have to have one of the computers always on, acting as some kind of file server or can the router do this job? This is a new router. My old one (whose power supply went phut) connected everybody without arguing about it and we could share files around, even with a mix of OSs.
Since this is a local network only, I have no firewalls enabled, as far as I know ...
All of the network set-up posts I've found rabbit on about how to get your internet connection working through your router, which is not an option for me. I have dial-up working on the XP computer and a mobile wireless USB dongle for internet access on the trusty desktop.
I've installed samba and a few other packages, but so far, none of them have solved my problem. Can someone please tell me where to start and which tutorials to read? If I have to set up a computer as a file server, I guess it will have to be the XP thing, as it's the only one that is always running, but I'd like to avoid that, if possible, as I speak XP worse than I speak Ubuntu.
BTW, D-Link are no help at all, two hours on the 'phone and they were still trying to get me to connect to an ADSL service I don't have ...

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.

Hello, My issue is very common but, not able to resolve it.

Issue I am facing with my Linux (RHEL-5 32-bit) machine, where I am not able to connect to internet.

DWR-113 - D-Link Router is configured for 3G dongle (Vodafone India) - This setup is done via WiFi and not using the provided LAN cable from Win7 machine.

Internet is working absolutely fine in case of Wireless but, at same time when LAN cable is used internet is not working. [Able to ping to Router IP i.e. 192.168.0.1)

Similarly, from Linux box, ping to Router IP is working [LAN plugged] but, Internet not working. IP of linux machine: 192.168.0.60

Also, able to get the console connection of Linux from Windows box..[Windows connected to Router via WiFi and Linux connected to Router via LAN cable]

Please suggest how to get rid of this problem so that Internet will work on Linux via LAN cable.

Many Thanks,

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.

Hello everybody,

I am seeking help regarding sharing internet connection. I would be greatful.

I have;
A Laptop : Samsung RV509, i3, 300GB HDD, 3GB Ram, Dual boot Windows7 & LM 17 cinnamon 32bit. WiFi & Bluetooth available. A Desktop PC : Celeron CPU 2.4GHZ, 40 GB HDD, 1GB RAM, LiveUSB-LM 17 cinnamon 32bit, No WiFi hardware available, No Bluetooth hardware available. A mobile phone : Nokia Asha 500, WiFi & Bluetooth available. An old USB data cable: with which the mobile phone can be connected to the computers. I have successfully connected and transfered data back & forth, and also shared/connected Mobile-Broadband-internet to both Laptop and Desktop.

What I have been doing now is; I have an internet connection to my Laptop with an external modem and Ethernet. Its working fine. I have an unlimited plan and so I want to share this internet connection on the mobile phone too; instead of incuring extra cost by connecting to the internet directly through the phone. I am successful at that. I can share this internet connection on my phone through WiFi.

Now, what I want to do is; without buying any extra hardware, to share this same internet connection on my Desktop PC, too.

What I tried is; I searched the web, but didn't find any solution. Now I am here. Please kindly help me.

Thank you & Regards

I bought an Asus Wireless Router RT-N66R yesterday, and it has successfully hooked up to everything around my home, except for my personal laptop. I run 14.04 Trusty Tsar on it. The wireless works for about 30 seconds before the computer stops recognizing it, and then I have to reconnect it again by clicking on the network name. Everything else in the house works great with it, and for the 30 or so seconds it stays connected to my laptop, my laptop works great as well. Also, when I am connected to Facebook, it tends to let me continue IMing people, even if I have no connection anywhere else. I can usually google my way to an answer, but I am really stumped on this one, please help!

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...

Urgent help is needed please

Alright, I followed this tutorial http://blog.qnology.com/2014/07/hack...nd-mobile.html To install linux on my Pogoplug v4 but when I restarted it just blinked green forever and nothing happened. I figured the OS did not install onto the flash drive and I was correct. I followed these instructions http://archlinuxarm.org/support/reinstallation and formatted the drive, got the correct Debian linux distro and put it on there, then put the drive back into the Pogoplug.

Success! Green light turned steady and the flash drive light flashed. After a few seconds it settled down but occasionally will access the flash drive (indicated by blinking USB light). Only problem is I cannot SSH into the pogoplug anymore. It has an IP address from the router. The router says its attached. But, when I use Putty to SSH into that address I get “Connection refused”

I know this is simple but I am very new to linux.

Thank you

Hello,I want to simulate seamless handoff b/w umts and 802.11,simulation works fine for one umts and one 802.11 base station but i want to simulate the senario of 3 802.11 base stations and one umts base station,when i add two 802.11 base stations,i got following error..
