Security and Cost Based Comparative Analysis of Prevention Methods of Black Hole Attack in Manet

Mobile ad hoc network (MANET) is a self-organizing network. It formed a network by using mobile nodes without any pre-defined structure. MANET has dynamic topology which allows nodes to join and leave the network at any point of time. Security is an important parameter in mobile ad hoc network (MANET) because of its built-in Vulnerabilities. These are temperament of MANET structure that cannot be removed. As a result, attacks with malicious intent have been and will be devised to exploit these susceptibilities and to cripple MANET operation. The black hole attack at network layer is the most concentration seeking attack in ad hoc networks. Prevention methods are very important to detect and prevent the different attacks in MANET. But securable and cost effective prevention methods are play vital role in MANET. This paper analyze the various prevention methods of black bole attack and present the report based on secured and low cost prevention methods for black hole attack.
