DETECTION AND PREVENTION OF SYBIL ATTACK IN WIRELESS SENSOR NETWORK EMPLOYING RANDOM PASSWORD COMPARISON METHOD
R. Amuthavalli, Raghuvel Subramaniam Bhuvaneswaran · 2014
Security is imperative for some Sensor Network Applications. An especially unsafe assault against sensor and impromptu systems is known as the Sybil attack, where a node illegitimately asserts numerous characters. In this type of attack a legal node is converted into a Sybil node which is a replica node with a different personality but using a similar ID. This leads to data leakage which causes data integrity violations. In existing research, nodes can detect the suspect nodes by checking the nodes in its neighborhood i.e within a given range. The neighbor nodes exchange information about each other and detect the Sybil node as it provides misleading information. The Sybil nodes are not detected directly by checking the ID or other node related information. In this paper, a Random Password Comparison [RPC] method is proposed that facilitates deployment and control of the position of node thereby preventing the Sybil attack. The RPC method is dynamic and accurate in detecting the Sybil attack. This method improves data transmission in the network and will also increase the throughput.
