To change the search engine in the search box of Firefox to Google, you just need to open Firefox then go to the following address:  

After that, click on the drop down list in the search box and select "Add Google"

To change the search engine of the address bar from DuckDuckGo to Google, you open Firefox , type about:config on the address bar. You will see a warning, just click on the "I'll be careful" button to go to the config page. In this config page, scroll down until you find the line that begins with "keyword.URL":

Right click on this line and select the Modify option. The box to edit the search engine will appear, in this box, you just need to replace the DuckDuckGo url with Google:  

Click ok .  Now both the address bar and the search box use Google as the default search engine.
3. Install new Themes and Icons 
 The best place to look for nice themes and icons in my opinion is Gnome-look . And get the themes and icons . Also remember to read the installation instruction of each theme and icon set.
 a conky setup
Install Conky in Ubuntu/Linux Mint open terminal (Press Ctrl+Alt+T) and copy the following commands in the Terminal:

cognitive radio cognitive network (CRCN) Simulator : in Linux mInt & ubuntu

Cognitive radio network is a new emerging research area recently.  It enhances the existing software-defined radio, whose physical layer behavior is largely defined in software.Cognitive radio has the following characteristics  

  •  it is aware of its environment and its capabilities
  • it is able to independently alter its physical layer behavior based on its previous experience and its current environment
  • it is capable of performing the complex adaptation strategies according to the cognitive cycle
With the spectrum opportunities provided by the cognitive radio network, the wireless network users are able to share the idle spectrum for TV channel, on the condition that it does not interfere with the normal TV channel. 

This cognitive radio cognitive network (CRCN) simulator is a software based network simulator for network-level simulations. It is based on open-source NS-2 (network simulator 2). CRCN simulator supports performance evaluations for the proposed dynamic spectrum resource allocation, power control algorithms, and the adaptive Cognitive Radio (CR) networking protocols including the CR MAC and the CR Routing protocols. This simulator uses NS-2 to generate realistic traffic and topology patterns. For each node in this simulator, a reconfigurable multi-radio multi-channel PHY layer is available by customizing the spectrum parameters such as transmission power, propagation and etc 
CRCN simulator enables the interface parameters transmission between different layers, as shown in arrows with blue color. Users just need to replace their own Routing and MAC algorithms according to NS-2 protocol design requirements with the existing one in the CRCN.

First Tcl script for beginners: "Hello World"

Hope you all have installed ns2 , now we can go for coding
As the ns2 simulations work on tcl scripts so we should know about tcl
Here some simple steps to write the "hello world" program in tcl

we can write tcl codes in two ways in interactive mode and in batch mode

first we can have look to interactive mode the terminal
             type  $ ns
2. a command prompt open
         Create a new simulator object by using the command
                        set ns [ new Simulator ]

This is Usually the first non-comment statement in ns-2 script 
- Initialize the packet format
   - Create a scheduler (default is a calendar scheduler)
   - Create a “null agent”

3.  to print text on screen we use puts command
               $ns at 1 "puts "\Hello World\""
    here we Schedule an event to write at the time 1 
      by this script simulator instance "ns" writes "hello World"
4.  now we have to exit the simulator object
                         $ns at 1.5 "exit"

 5. now we have to run the simulator object,
                      $ns run
this starts ns
and this prints hello world

In batch mode  its much simple

open a text editor and write the codes there and save it with .tcl  file extention 


 hello.tcl :

set ns [new Simulator]
$ns at 1 "puts \"hello world\""
$ns at 1.5 "exit"
$ns run

open the terminal and execute the hello.tcl by
            $ ns hello.tcl


How to Install NS2 and NAM in linux mint & Ubuntu

 Take a look into the installation of a very famous tool that is widely used in Network related researches. Network Simulator or NS as it is popularly called is formally defined as a "discrete event simulator". For a post graduate in Computer Engineering or a PhD scholar it is, in simple terms, a valuable tool that greatly aids in simulating their concepts in wired and wireless networks.

 To install NS in Linux
