Safety concerns of Sybil attack in WSN

Securing Grid protection in Wireless Sensor Grids (wireless sensor networks) several attacks that have been recognized in wireless sensor network till now by the researchers and still it´s increasingly becomes critical. Sybil attack is one of the harmful attacks against sensor Grid where a number of appropriate individualities and forged individualities are used to get an inappropriate entry into the network. Essentially a Sybil attack means a system which pretends its individuality like further nodes. In this scenario a system can trust the reclose system and it start sharing its data. Due to this activity a node´s safety is affected and data is lost. In this paper, a survey is done on Sybil attack and projected a mutual RAI - Relate and Identify Tactic and LVT Location Verification technique to avoid these attacks.
