TOUR DE NS2: WHERE TO START

Hey All, On early stage everyone has a confusion that What hardware I needed? What are the minimum requirement for ns2? What OS I need for installation? Where can I find ns2 software package? How do I install my package?  Huh. A lot!!!!  😖😖😕😥

Don't worry!!! 😄Ns2 Bloggers is here to help you. Lets start from scratch. Hurrayyyy!!!!!!!!!😀😀

Minimum Machine Requirement

The answer is simple: Any computer with reasonable Memory and Storage. Simple scenarios should run on any reasonable machine, but very large scenarios benefit from large amounts of memory.

There is no such suggestions available from official sites about machine requirements. Still, ns2bloggers suggest following configuration;

  • Processor with a speed of 500MHz and above.
  • RAM of minimum 64MB.
  • Hard disk of minimum 500MB. NS2 package is fairly a large package. The allinone package requires about 320MB of disk space to build. 

All laptops/Computers available in the market are advanced than this. So, you can use a better  configuration than the basic requirement. 

OS Requirement and Installation Procedure

No need to worry about this, now ns2 supports in Windows, Linux and MAC. But each one has different installation procedure. You can see installation procedures from the following links;

Software Package

There are two ways to build ns:

  • From all the pieces
  • All at once

 If you just want to try it out quickly, you might try all at once. If you want to do C-level development, or save download time or disk space, or have trouble with all-in-one you should build it from all the pieces. The available latest version of ns2 is ns2.35.

All at Once Package

You can download ns2.35 allinone package from following here

From all the pieces

If you are a pro or you want to save some space, you can definitely install ns2 from pieces. Ns depends on several externally available components. Below is a summary of where to get them and where they may already be (if you're a VINT developer). Since the components depend on each other, you should build them in the listed order.

Tcl/Tk
  • A modestly up to date Tcl/Tk version Tcl/Tk-8.5
  • web page: Tcl Developer Xchange resources.
    Note that while more up to date versions of Tcl/Tk are available and may work, we have only tested up through version 8.5.10.

otcl

TclCL (the package formerly known as libTcl)

ns-2

nam-1 (optional)

You can find pre-built binary of nam-1.11 for Linux/freeBSD from the nam page.

xgraph (optional, but needed for test suites)
            Download source:version 12.1, or by anonymous cvs (module "xgraph"). 
  Web page: http://www.isi.edu/nsnam/xgraph/.

(This version is maintained by the ns maintainers and includes portability fixes over the older 12.0 release.)

perl (optional, but needed for test suites)
Download source: latest stable release; web page: http://language.perl.com/

Note that version 5.003 or later is required.

tcl-debug (optional, available for Tcl debugging help)
Download source: version 1.7;
Web page: http://expect.nist.gov/tcl-debug/. This version will work with Tcl/Tk 8.0 release.

dmalloc (optional, available for memory debugging)
Download source: version 4.8.0. 
Web page: http://www.dmalloc.com; specify --with-dmalloc during configure to include.

sgb2ns conversion program (optional, needed to convert GT-ITM output to ns-2 format)
Download source: sgb2ns conversion program. For more info on GT-ITM topology generators see GT-ITM Topology Generator.

tiers2ns conversion program (optional, needed to convert Tiers output to ns-2 format)
Download source: tiers2ns.awk. For more info on Tiers topology generators see Tiers Topology Generator.

Cweb and sgb source code (optional, required to create sgb-library that is used by gt-itm and sgb2ns programs)
Download cweb source from cweb ftp page
Download sgb source code from sgb ftp page

VINT developers at ISI can find all of these packages in /nfs/filb2/public/pkgs.

 Please note you have to check the bug fixes after you finish installation! 


Happy Coding.... 😉😉

Link State Routing Protocol

Link state routing is a method in which each router shares its neighborhood’s knowledge with every other router on the internetwork. In this algorithm, each router in the network understands the network topology and then makes a routing table depending on this topology. Each router will share data about its connection to its neighbor, who will, consecutively, reproduce the data to its neighbors, etc. This appears just before all routers have constructed a topology of the network. In LSP, each node transmits its IP address and the MAC to its neighbor with its signature. Neighbors determine the signature and maintain a record of the combining IP address and the MAC. The Neighbor Lookup Protocol (NLP) of LSP derives and maintains the MAC and IP address of every network frame accepted by a node. The extracted data can support the mapping of MACs and IP addresses. The link-state flooding algorithm prevents the general issues of broadcast in the existence of loops by having every node mainta...

Matter: A next generation home standard

The smart home is evolving. To date, if you've wanted to get into developing a smart home, you've had to deal with the multitude of smart home ecosystems, and making sure that each device you buy is compatible. That, however, may soon change — thanks to new smart home standard called Matter. Matter isn't available just yet, but when it is finally released, it could completely change how you buy smart home products, for the better. All of the best smart home devices could soon support the standard, helping them all work together nicely, and ensuring that no matter what products you buy, you'll be able to use them. Matter is basically the name of a new smart home connectivity standard . But this standard is a little unlike others. That's because of the fact that it's being developed by the Connectivity Standards Alliance, which counts hundreds of companies as members. That includes the likes of Google, Alexa, and Apple. So, whether you prefer to use Google Assista...

New interactive stickers for Stories

Instagram has introduced several new features to Stories, offering interactive ways to share music, photos, and videos. One of the most interesting additions is a feature called Reveal , which blurs the content of a story post and requires viewers to DM the person who shared it in order to see it. Instagram's head, Adam Mosseri, has emphasized the importance of direct messages on the platform, with stories and DMs driving most of Instagram's growth. Requiring a DM to view content represents the next step in boosting engagement, and creators are likely to use it as a tactic to increase their stories' engagement. Another new feature, Frames, adds a Polaroid overlay to images that initially appear gray. Users can shake their phone to reveal the photo, resembling the process many people associate with Polaroid pictures, despite the fact that shaking Polaroids is not recommended by the company during development. Instagram has also introduced a music-based template feature calle...
