A Hybrid Model To Detect Sybil Attacks In Wireless Sensor Network
Wireless Sensor networks finds its application in various areas such as habitat monitoring, home automation, industrial automation, military applications and health care etc. Security in sensor networks is muddled by the broadcast idea of the wireless communication and the absence of alter safe hardware (to keep per-node costs low). Likewise, sensor nodes have restricted storage and computational resources, rendering public key cryptography unreasonable. We propose a Surplus Energy Scheme based on excess energy, to additionally distinguish the Sybil attack node sneaked through the main request high-energy nodes. This is happens on the second-request high-energy nodes. This paper proposes a hybrid technique for improving the detection pace of Sybil attack in WSNs. The proposed hybrid model contains three basic stages. The experiment result proves that the proposed method provides better result.
