Self Organized Security Aware Routing Over Mobile Adhoc Network

ABSTRACT

Mobile ad hoc networks operate in open environment and there is no centralized controller to monitor the network operations so it is quite easy to intercept the communication over these networks by introducing active and passive attacks. In this paper, the impact of Grayhole attack over AODV routing protocol is analyzed and a prevention scheme is introduced to overcome from the compromised situation. We will also analyze the behavior of routing protocol by varying the attacker’s node density variation under the various constraints i.e. Throughput, routing load and PDR.
