Security Provision in Wireless Sensor Networks on the Basis of the Trust Model

Аннотация

This article considers security provision in wireless sensor networks on the basis of the trust model. The operating principles of sensor networks are analyzed, and the classification of routing techniques is composed. Typical threats are analyzed and existing attacks against Wireless Sensor Networks (WSNs) identified. A technique of protection against malicious nodes is elaborated using the trust model. The experimental assessment of the technique for efficiency is performed by modeling its work in a WSN simulator.
