Software-fault mitigation for derivation of quality of services (QoS) in wireless sensor networks (WSN)

A ‘Wireless Sensor Network’ (WSN) is a network of autonomous sensors spread out in any environment that is required for the surveillance of environment’s physical condition like pressure, temperature, humidity etc. These sensor networks are used in extreme environmental conditions which can lead to their failure and the damage of the entire environment. Thus, fault detection methods are the need of the hour. Fault tolerance, which is considered a challenging task in these networks, is defined as the ability of the system to offer an appropriate level of functionality in the event of failures. In order to provide better QoS, it is essential that faulty nodes should be diagnosed and handled timely without affecting the underlying work of the network. The present study proposed a throughput efficient mechanism in order to improve fault tolerance of the system against software faults. Since the proposed methodology works on the input variables that are collected on real time basis thus adding to its efficiency in fault detection process. The result shows that our proposed work diagnosis different software faults and during fault diagnosis it is able to maintain the desired throughput. The efficiency of the proposed algorithm is achieved by comparing it with the previous algorithms so far present in the literature. © 2020 Lavoisier. All rights reserved.
