Abstract

Security is always the critical challenge for mobile network and it suffers from various internal and external attacks. These attacks use the dynamic and cooperative communication features of the network and disrupt the communication. In this paper, a study on various network attacks and their impact is defined. The paper also explored the blackhole attack in larger extent. The work procedure of these attacks, features and characterization of blackhole attack are defined. The paper also discussed some of the major methods defined to detect and prevent the black hole attack.
