Trust Based Routing to Detect Black Hole Attacks in Wireless Sensor Networks - A Survey

A Wireless Sensor Network (WSN) has a wide range of application, slowly becoming an integral part of the living life. Wireless means the node can communicate without any physical media, i.e., the data is transmitted from one node to another in the form of packet. WSN is being deployed for many real time applications where the dynamical monitoring of sensed data is required. Sensor networks are application-specific and the routing of data between the sensor nodes has to be without interruption and errorless. Routing protocols try to incorporate methods to ensure avoidance of misbehavior of intermediate nodes. The trust among the distributed network is generally used as a powerful tool to improve the performance of sensor networks. This paper presents a detailed survey on the security and trust communication between the sensor nodes with routing techniques to detect and prevent data packet from the being exposed to Black hole attack. The paper also concludes with a comparison among the existing works.
