As the technology improves the method of communication and reduces the network overhead it also opens a wide spectrum for attacker to break the security. As wireless communication happens through open air, it also increases possibility of fetching the information from air medium using sniffing software tools. A particularly harmful attack against sensor networks is known as the Sybil attack, where a node illegitimately claims multiple identities and simultaneously uses those identities in the network. In this paper, the authors analyze fake identity in network which is created by Sybil attack by detecting its source.
