NS2 INSTALLATION FROM GITHUB

Hey, Today we are discussing abou a simple and easy port of the popular Network Simulator NS2 for the windows platform. For this method, there is no need of cygwin or virtual box. Is that Interesting???

Steps:

1. Downloading essential directories:

Download.zipor usegit from here.

Unzip the zipped file in your preferred directory.

2. Installation of Software

Install chocolatey

Chocolatey takes care of your environment variables and all the nuances when it comes to installing new software which require some specific paths to executables to be present as home variables.

This step may take a couple of minutes.

Run CMD prompt as administrator (system/32) once the installation is complete. Run the following command to install gawk.

choco install gawk

This step may take a few moments.

Navigate to the necessary directory where you have this repository cloned/unzipped.

That's all, its ready for execute program.

Now type, ns helloworld.tcl

If all your setup has been done perfectly, you should get the following output:

Hello World - TCL
Hello World - AWK

The NS Wireless animator window should also pop up.

Write your tcl and awk files in the same directory where you have your ns.exe file. Alternatively, you could set an environment variable with the path to the ns.exe file.

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...
