Efficient Approaches to Mitigate the Effect of Sybil Attack in MANET for High Network Lifetime: A review

MANET is known as a self configuring, dynamic infrastructure to connect mobile devices through wireless. There are several challenges which affect the MANET, such as routing, security and reliability, power consumption, inter-networking, multicast and so on. M Being in such environment, some malicious behaviour can affect the security of networking. This mystifying situation usually occurs in MANET because of the intrinsic design defects. Malicious nodes which are generated using Sybil attack intentionally drop all packets which are having destinations to the target locations by making the duplicate copy of the original nodes. Malicious nodes disturb the linking of the network. Selfish type of nodes aims to reserve their resources, and degrades the network performance. Our paper targets to explore various detection and mitigation approach of Sybil attack. This paper classifies and exhibits every mechanism as per certain perspectives.
