Trust management techniques in Wireless Sensor Networks: An evaluation

A Wireless Sensor Network (WSN) is a network which comprised of multiple low cost sensor nodes. In WSN, each sensor is deployed in a different location for a specific purpose. Due to unstable conditions, sensors are unable to perform an anticipated result. At this stage, we totally loose our security and it shows inaccuracy result. So we concentrate on the mutual trust between the source-to-sink and vice versa in a WSN. Trust has been recently suggested as an effective security mechanism for managing each sensor node. In this paper, we investigated some stable trust management techniques for a high trust in WSN. From the techniques we believe to form a strong trust model on sensor communications over a WSN. In this paper, we also evaluated the finest trust model for WSN using TRMSim-WSN 0.4 Simulator. This simulator consists of various trust models and each model performs the different results. The analytical result demonstrates its effectiveness in managing trust relationships and techniques.
