FEBSRA: Fuzzy Trust Based Energy Aware Balanced Secure Routing Algorithm for Secured Communications in WSNs

Energy efficiency playsa major role in designing a sensor network to improve network lifetime. Trust is also important for providing security to the data communication process. Delay is also a major challenge today due to the enormous volume of network users. To overcome all these issues, many researchers have developed energy-efficient security mechanisms for fulfilling the requirements. Even though they are not able to satisfy the current requirements and users in terms of energy consumption, delay, and security. For this purpose, this paper proposes a new algorithm called Fuzzy Trust-Based Energy-Aware Balanced Secure Routing Algorithm, which can provide the effective delay constrained secure routing. It uses fuzzy logic as a form of many-valued logic. In this method, the truth values of variables may be any real number between 0 and 1, both inclusive for making a final decision over sensor nodes. Considering the number of hops between the source and destination nodes, the energy level of the nodes, the trust scores. Moreover, a new trust model has introduced a new formula for calculating trust scores with the energy level of the communication delay, which is calculated by using the number of hops used for the specific communication, taking into account the number of hops between the source and destination nodes. The experimental results of the proposed secured routing algorithm demonstrated that the performance in terms of energy consumption, less delay, and high throughput with security is better when compared to the existing systems.
