Detecting and Avoiding Sybil Attack in OLSR Protocol

Amit Kumar ^[66] | Varun Singla

Abstract: The ad hoc network is an infrastructure less wireless network consisting of mobile moving nodes. VANETs is the recently developed technique to achieve traffic safety and efficiency through inter vehicle communication, where routing protocol plays a vital role. Inefficient network security brings the severe degradation in network throughput and performance. Routing throughput and performance is largely dependent on the availability and security of the wireless link which makes it a very pivotal parameter, that cant be ignored in order to obtain proper performance and throughput measurement in VANETs. Secured routing is greatly dependent on the availability, performance and stability of the wireless links, which makes it a vital parameter that shouldnt be neglected in order to obtain proper security measurement in VANET. Many malicious vehicles demean the functioning of network by actuating some attacks So this work presents a refreshing technique that has been put forward to search malicious vehicles and remove the attack i. e. Sybil attack from the OLSR routing protocol. This remotion of attack from the OLSR protocol will increase the performance and stability of the network.
