EFT: Novel Fault Tolerant Management Framework for Wireless Sensor Networks

Abstract

The main application of wireless sensor networks is monitoring, and the nodes of these networks are located usually in harsh environments. Network management is the most important factor in network operation and efficiency. From the perspective of distributed management task force, management should have FCAPS features. In the FCAPS word, the letter F stands for Fault tolerance, the letter C stands for configuration, the letter A represents the accounting, the letter P represents the performance, and the letter S stands for the security. So the first feature is fault tolerance. This paper proposes a management framework for wireless sensor networks that both increases the quality of fault tolerance and decreases the energy consumption of the network. Due to the very fact that the nature of the relationship between energy consumption and fault tolerance is essentially a trade-off, the proposed framework will bilaterally increase the network lifetime. Based on the results, implementing this framework will noticeably increase fault tolerance and decrease the energy consumption. Moreover, for protocols with cluster heads that change frequently at the end of each round, simulations have shown comparatively more success.
