Beta Reputation and Direct Trust Model for Secure Communication in Wireless Sensor Networks

WSN is a collection of tiny nodes that used to absorb the natural phenomenon from the operational environment and send it to the control station to extract the useful information. In most of the Existing Systems, the assumption is that the operational environment of the sensor nodes deployed is trustworthy and secure by means of some cryptographic operations and existing trust model. But in the reality it is not the case. Most of the existing systems lacks in providing reliable security to the sensor nodes. To overcome the above problem, in this paper, Beta Reputation and Direct Trust Model (BRDT) is the combination of Direct Trust and Beta Reputation Trust for secure communication in Wireless Sensor Networks. This model is used to perform secure routing in WSN. Overall, the method provides an efficient trust in WSN compared to existing methods.
