A MANET has many wireless nodes that are arbitrarily moving and communicating each other. The communication is without the use of any central coordinate or base station. It is infrastructure-independent network. It has different unique characteristics that make it more complex in routing. The routing decision is made in a decentralized manner. Although many protocols have been proposed for wireless communication, the ADOV is most widely used. The intermediate node helps to transmit data packets from source to destination. The interference of intermediate nodes introduces some serious attacks in mobile ad hoc networks. Some of them are gray hole, black hole, flooding, and selfish node attacks. In this chapter, the gray hole and cooperative attack prevention method is discussed and the results of the same are presented. |
