The shared nature of the medium in wirelessnetworks makes it easy for an adversary tolaunch a Wireless Denial of Service (WDoS)attack.

Recent studies, demonstrate that suchattacks can be very easily accomplished usingoff-the shelf equipment.

To give a simple example, a malicious nodecan continually transmit a radio signal in

order to block any legitimate access to themedium and/or interfere with reception


3/19

ABSTRACT(Continued):This act is called jamming and the maliciousnodes are referred to as jammers.Jamming techniques vary from simple ones

based on the continues transmission of

interference signals, to more sophisticatedattacks that aim at exploiting vulnerabilities ofthe particular protocol used.

A detailed up-to-date discussion on the

jamming attacks recorded in the literaturewill be discussed in this project.


4/19

ABSTRACT(Continued):

This project also describe varioustechniques proposed for detecting the

presence of jammers.Finally, the project conclude with a

summary and by suggesting future

directions.

SECURITY is one of the critical attributes ofany communication network. Various attackshave been reported over the last many years.

Most of them, however, target wired

networks. Wireless networks have onlyrecently been gaining widespreaddeployment.

At the present time, with the advances in

technology, wireless networks are becomingmore affordable and easier to build

EXISTING SYSTEM(Continued)

Many metropolitan areas deploy public

WMANs for people to use freely.

Moreover, the prevalence of WLANs as

the basic edge access solution to the

Internet is rapidly becoming the reality.

However, wireless networks are

accompanied with an important security

flaw; they are much easier to attack than

any wired network


7/19

This project describes some ofthe most harmful attacks that

can be launched by a jammer.We develop such one system,to show the effect of the dos

attack.

PROPOSED SYSTEM (Continued)

In the project proposed system, the

normal client and server process is

initially depicted, then the attack is

launched manually to show how the

dos attack affect the normalclient/server process.

At this moment of time the Location

Guard will find the abnormalbehavior of packets and filter the

packets that are related to jammers.

PROPOSED SYSTEM (Continued)


10/19

The most common set of requirements definedby any operating system or softwareapplication is the physical computer resources,also known as hardware. The hardware

requirements required for this project are: 20 GB of Hard disk 256 MB RAM Pentium 133 MHZ or above (Processor)

PCs which are interconnected in LAN Network Adapter card configured with an IP

address


11/19

Software Requirements deal withdefining software resourcerequirements and pre-requisites thatneed to be installed on a computer to

provide optimal functioning of anapplication. These requirements orpre-requisites are generally notincluded in the software installation

package and need to be installedseparately before the software isinstalled.

SOFTWARE REQUIREMENTS (Continued)

The software requirements for thisproject are:Java 1.3 or later versionsWindows 98 or later versions
