Final year Project (A Sybil Attack Detection in Wireless Sensor Network)
Abdul Wali Khan University Mardan
A lightweight Sybil attack detection scheme for a centralized cluster-based hierarchical network is proposed. In Sybil attack, an adversary forges multiple identities to the legitimate nodes. An adversary may either fabricate such identities or steal them from legitimate nodes by disabling them permanently. The existing Sybil attack detection techniques are designed primarily for data-centric routing protocols in which flooding technique is used to regulate traffic flow. Flooding allows intermediate nodes to broadcast data and control packets on their way to a base station from source nodes. Duplicate packets keep circulating in the network which causes excessive energy consumption, delay, congestion, implosion and overlapping. We detect that sybil node and block it so that not take part in networking.
