Abstract

In wireless sensor networks (WSNs), sensor nodes are deployed densely in large numbers to increase the quality of services (QoS). However, QoS is significantly affected by faults in such networks. The probability of faults in WSNs increases with increase of sensor nodes. 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. In this paper, our main focus is on diagnosing transient and permanent fault by communicating an optimal number of messages. We propose a mechanism to diagnose such faults without degrading the throughput of WSNs. The proposed approach is reactive in nature, which during fault diagnosis generates traffic smoothly in the network due to which the network never degrades its performance. Scheme also allows faults to occur during diagnosis process. The result shows that our scheme diagnoses faults correctly and efficiently and is able to maintain the desired throughput during fault diagnosis.
基于吞吐量下降和能量效率的无线传感器网络故障检测机制
在无线传感器网络(WSNs)中,为了提高服务质量,传感器节点被大量密集地部署。但是在这种网络中,故障对QoS的影响很大。随着传感器节点的增加,传感器网络的故障概率也随之增加。为了提供更好的QoS,必须在不影响网络底层工作的情况下及时诊断和处理故障节点。在本文中,我们的主要重点是通过通信的最优数量的消息来诊断瞬态和永久故障。我们提出了一种不降低无线传感器网络吞吐量的故障诊断机制。该方法本质上是被动的,在故障诊断过程中可以平稳地在网络中产生流量,从而不会降低网络的性能。方案还允许在诊断过程中出现故障。结果表明,该方案能够准确、高效地诊断故障,并能在故障诊断过程中保持所需的吞吐量。
