Response time optimization with enhanced fault-tolerant wireless sensor network design for on-board rapid transit applications

Abstract

In the recent decades, rapid transit system (RTS) plays a significant key role to form most affordable and comfort travel zone to humans. With increase in population and usage of RTS, safety measures are concerned to be most notable factor in the world. Moreover, during emergency cases internal wired safety setups of any RTS does not prevents drastic disaster and allows negative impact for on-demand reliable changes. As an alternative to other expensive technologies, wireless sensor network (WSN) system provides fast communicative and compact applications to RTS. Inorder to reduce causalities, designing such a network application to RTS always poses challenging problems in terms of fault tolerance and time bounded packet delivery. Integrated fuzzy-logic based synchronized data transmission (IFSDT) algorithm has been designed to optimize those challenges, especially in RTS. IFSDT is a synchronized energy aware algorithm that prevents the occurrence of potential faults during unexpected emergencies in the coaches of RTS and ensures the fast transmission of critical broadcast signal and response in a limited time span. Furthermore, the results of the proposed design performs better than the existing reliable and energy optimized WSN design and exhibits the optimized response time for broadcasting emergency signals which is below 0.02 s.
