Abstract :

Wireless sensor networks are a crucial component of any Internet of Things (IoT)-based system. Fault tolerance in wireless sensor networks equipped with IoT is essential to avoid detrimental actions. Numerous approaches in the literature focus on fault detection and tolerance for these networks. However, these methods often consume more energy to identify and tolerate failures or utilize additional hardware and software resources. Despite the promise of IoT, awareness of network reliability remains a significant challenge. Broken links and faulty nodes can severely affect the reliability of IoT-enabled networks, hindering seamless communications and data exchanges. This paper presents a routing method that ensures reliability and fault tolerance in IoT-based wireless sensor networks using a Poisson distribution foundation. The aim of this approach is to enhance the true positive rate, false alarm rate, fault detection accuracy, energy consumption, detection precision, and overall network longevity. We implemented and evaluated both the proposed method and the baseline method in a MATLAB environment. Simulation results indicate that the proposed method outperforms the baseline approach.
