Energy-Efficient Trust and Quarantine-Based Secure Data Transmission in Wireless Sensor Networks

Wireless Sensor Networks (WSN) are comprised of a significant amount of sensors that are dispersed to acquire data regarding a certain region. The sensor nodes are self-contained and create an ad-hoc inter-communication topology with one another. On the other hand, sensors are limited by their limited resources for managing energy, storing data, communication, and computing power. The hacked nodes make the information more susceptible to security issues. The safety of an unreliable network is a source of concern for researchers. To reduce energy consumption and provide secure communication this research work aims to present an energy-efficient secure data transmission system for WSNs that use the trust concept to detect and prevent data compromise while providing high performance. The proposed method comprises two main steps: First, it presents a new data security scheme that includes data confidentiality and integrity. Second, use the trust concept for analyzing the quality of data links for secure transmission and quarantine nodes and edges based on the trust value. The outcomes of the simulation showed that the suggested protocol increases the effectiveness of network lifetime and energy usage.
