Secrecy diversity analysis for physical-layer security of Wireless Sensor Networks

Abstract

  Secrecy Diversity Analysis is to improve Physical Layer Security (PLS) in Wireless Sensor Networks (WSNs). Wireless Sensor Networks (WSNs) are more susceptible to security risks owing to the broadcast characteristics of wireless communication, necessitating the protection of sensitive data. The research examines the application of diversity strategies to enhance secrecy performance in wireless communication networks. Utilizing variety, including antenna diversity and channel diversity, the system can bolster resilience against eavesdroppers and augment the overall secrecy capacity. Employing MATLAB alongside Simulink as the simulation instrument, multiple secrecy performance measures are assessed, including secrecy capacity and secrecy outage probability. The simulation results indicate that the incorporation of diversity approaches at the physical layer markedly enhances the security of wireless sensor networks, diminishing the probability of eavesdropping and augmenting system resiliency. This research emphasizes the significance of integrating PLS with diversity approaches to improve security in resource-limited wireless systems such as WSNs.
