ABSTRACT
Voice over Internet Protocol (VoIP) has become a popular alternative to traditional public-switched telephone network (PSTN) networks that provides advantages of low cost and flexible advanced “digital” features. The flexibility of the VoIP system and the convergence of voice and data networks brings with it additional security risks. These are in addition to the common security concerns faced by the underlying IP data network facilities that a VoIP system relies on. The result being that the VoIP network further complicate ....etc

abstract:
The occurrences of mobile worms like Cabir, Mabir and CommWarrior have created growing concerns over the security of data stored on mobile devices such as cell phones and PDAs. These worms have in common that they all use Bluetooth communication as their infection channel. In order to prepare effective defense strategies against such worms, we study the nature, characteristics, and spreading dynamics of Bluetooth worms in the safe environment of simulation. Our key findings are: (i) mobility may not boost the Bluetooth worm propagati ....etc

INTRODUCTION
As the semi-conductor technology is experiencing rapid growth, human life gets complicated without “embedded system”. Nowadays these new technologies are introduced in the equipments engaged in the battlefield to improve the safety of soldiers and also to ensure combat effectiveness. Our scope is to develop a mechanism to automatically control the movement of the air defense gun mounted on the tank. To understand our project better, let’s consider our indigenous tank ‘ARJUN’ designed ....etc

Abstract
In a bandwidth-flooding attack, compromised sourcessend high-volume traffic to the target with the purpose of causingcongestion in its tail circuit and disrupting its legitimate communications.In this paper, we present Active Internet Traffic Filtering(AITF), a network-layer defense mechanism against such attacks.AITF enables a receiver to contact misbehaving sources and askthem to stop sending it traffic; each source that has been asked tostop is policed by its own Internet service provider (ISP), which ensuresits compliance. ....etc

INTRODUCTION
Surveillance, Espionage or spying involves individual obtaining information that is considered secret or confidential without the permission of the holder of the information. Spying area in military ground where enemy stay can be took before taking any action.
A robot is a virtual or mechanical artificial agent. In practice, it is usually an electro mechanical system which, by its appearance or movements, conveys a sense that it has intent or agency of its own.
Our aim in building this projec ....etc

Novel Defense Mechanism Against Data Flooding Attacks In Wireless Ad Hoc Networks

– Consumer Electronics – Java

Mobile users like to use their own consumer electronic devices anywhere and at anytime to access multimedia data. Hence, we expect that wireless ad hoc networks will be widely used in the near future since these networks form the topology with low cost on the fly. However, consumer electronic devices generally operate on limited battery power and therefore are vulnerable to security threats like data flooding attacks. ....etc
