Impact Evaluation of Sybil Attack on Manet's for Reactive Routing Protocol
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 7
Abstract
A number of attacks have to be faced by mobile ad hoc networks like sybil attack. In the present this as well, the focus is on the practical evaluation of effective way to detect and prevent a Sybil attack. When a Sybil attack, the reputation system of current work is subverted by generating a large number of fake identities and these are used to achieve disproportionately large influence on the network. A Sybil attack is dangerous for security as well as the trust of the network. In this case, the running of the network is compromised. There are several methods that have been offered earlier by various researchers for the purpose of mitigating Sybil attack from MANET that all of these and have their individual benefits and limitations. In the present research work, first of all, we are going to detect the Sybil attack and then to prevent the attack in order to uphold the overall performance of the network. In the present research work, the method being investigated is based on three step algorithm: (i) monitoring (ii) trust value; and (iii) isolation. First of all, the nodes in the network will be monitored and then maintained trust value will be used to differentiate between legitimate and Sybil node, and in the end, the Sybil node will be isolated from the network. This work will be practically evaluated by using network stimulator (NS2) by evaluating throughput, end-to-end delay and packet delivery ratio in case of various network conditions.
