Optimizing the Reliability and Performance of Service Composition Applications with Fault Tolerance in Wireless Sensor Networks

Abstract

The services composition technology provides flexible methods for building service composition applications (SCAs) in wireless sensor networks (WSNs). The high reliability and high performance of SCAs help services composition technology promote the practical application of WSNs. The optimization methods for reliability and performance used for traditional software systems are mostly based on the instantiations of software components, which are inapplicable and inefficient in the ever-changing SCAs in WSNs. In this paper, we consider the SCAs with fault tolerance in WSNs. Based on a Universal Generating Function (UGF) we propose a reliability and performance model of SCAs in WSNs, which generalizes a redundancy optimization problem to a multi-state system. Based on this model, an efficient optimization algorithm for reliability and performance of SCAs in WSNs is developed based on a Genetic Algorithm (GA) to find the optimal structure of SCAs with fault-tolerance in WSNs. In order to examine the feasibility of our algorithm, we have evaluated the performance. Furthermore, the interrelationships between the reliability, performance and cost are investigated. In addition, a distinct approach to determine the most suitable parameters in the suggested algorithm is proposed.

Reliable Fault Tolerant-Based Multipath Routing Model for Industrial Wireless Control Systems

“…This will significantly reduce the reliability of sensor nodes, and diminish or disrupt the normal functioning of wireless networks. The network's performance has been severely hampered, and it will face significant hurdles in terms of adaptability, robustness, and reliable data transmission [15]. The reliability and accuracy of data transmission are intimately linked to successfully implement wireless networks.…”

“…These failures will have an effect on the topology stability and data transmission reliability, and consequently, degrade the overall comprehensive network performance. The network's health is crucial for wireless sensor networks to operate reliably, transmit data reliably, and optimize performance [15] For these reasons, it is necessary to build fault-tolerant based multi-hop and routing mechanisms that require the least amount of additional computation despite the fact that they may also require additional communication in order to construct or recover the damaged paths due to a node or link failure [17]. Network stability and reliability are improved by the use of fault tolerance methods, which employ techniques or algorithms to grant a reliable data transfer in order to increase the reliability and stability of networks [16].…”
