In network attacks, the attacker injects a large amount of spam packets into the network which leads to the crashing of network utilities and causes congestion in network.  For codes, Click  here

 Tcl (Tool Command Language) is a very powerful but easy to learn dynamic programming language, suitable for a very wide range of uses, including web and desktop applications, networking, administration, testing and many more. Open source and business-friendly, Tcl is a mature yet evolving language that is truly cross platform, easily deployed and highly extensible. Tk is a graphical user interface toolkit that takes developing desktop applications to a higher level than conventional approaches. Tk is the standard GUI not only for Tcl, but for many other dynamic languages, and can produce rich, native applications that run unchanged across Windows, Mac OS X, Linux and more. Core Development A wide variety of developers contribute to the open source Tcl and Tk core, which is hosted at core.tcl.tk. The Tcl Core Team (TCT) helps steer this development through mechanisms like Tcl Improvement Proposals (TIP's) and the core mailing list. For more, C lick  here

  Lot of people mailed us about how to calculate distance between neighbor nodes or between source and destination?? Now we added some scripts in front end program i.e in tcl script to find out distance between source and destination or with neighbor nodes.  We used distance calculation equation to find out the distance between two nodes.If (x1,y1) be the position of first node and (x2,y2) be the position of second node.Then,distance (d) between two nodes is given as; d=[ (x2-x1) 2 +(y2-y1) 2  ] 1/2 For Script ,C lick   here .

  Gnuplot is a portable command-line driven graphing utility for Linux, OS/2, MS Windows, OSX, VMS, and many other platforms. The source code is copyrighted but freely distributed (i.e., you don't have to pay for it). It was originally created to allow scientists and students to visualize mathematical functions and data interactively, but has grown to support many non-interactive uses such as web scripting. It is also used as a plotting engine by third-party applications like Octave. Gnuplot has been supported and under active development since 1986.  Gnuplot can be used to visualize the trace file data; several network parameters can be plotted using this Gnu plot..for more details  click here

  UM-OLSR UM-OLSR is an implementation of the OLSR (Optimized Link State Routing) protocol for the  ns-2 Network Simulator . The code is released under the terms of the GNU General Public License ( GPL ). Due to lack of time this project is not maintained by myself any more, feel free to take over the task of maintenance if you are interested. UM-OLSR complies with IETF RFC 3626 and supports all core functionalities of OLSR plus the link-layer feedback option. The software has been successfully tested on ns-2, and patches for several versions of the simulator are provided. It is widely employed by the wireless communications research community, as the high number of references in research papers reveal. In addition, it was ported to ns-3 by Gustavo Carneiro (INESC Porto) and to Omnet++ by Alfonso Ariza (Universidad de Málaga). Thus, you can also run OLSR simulations in modern network simulators.        Features Compliant with core OLSR (as described in RFC ...
