Comparison between Sybil Attack Detection Techniques: Lightweight and Robust
|Related article at Pubmed, Scholar Google|
Mobile ad-hoc network (MANET) is an independent network which consists of many nodes and these nodes uses wireless links to communicate with each other. The infrastructure less nature of MANET makes it vulnerable to various attacks. There is an attack which causes many serious threats to the network and it is known as Sybil attack. In Sybil attack, attackers or malicious nodes uses many identities or IP addresses to gain control over the network and creates lots of misconception among nodes present in the network. In this paper two approaches are discussed to detect the Sybil Attack, one is Lightweight Sybil Attack Detection Approach and other is Robust Sybil Attack Detection Approach.
