摘    要:无线传感器网络在工业领域应用广泛,由于电磁干扰、电源突然中断、软件突发错误等瞬时故障导致系统失效,影响系统安全,其控制和恢复在涉及安全的领域越发得到重视。考虑到瞬时故障在网络的多个层次可能都有发生,提出了一种三层故障处理机制,在芯片级采用硬件逻辑调整、在节点级采用重传和跳频、在系统级采用冗余路由等措施进行故障控制和恢复。实验结果表明,采用三层故障处理机制后,网络的丢包率和端对端的时延有效降低,节点通信的可靠性和安全性得到有效的提高。

关 键 词:无线传感器网络  通信  瞬时故障  故障恢复

Abstract:Now the wireless sensor network is widely used in the modern industrial filed. System failure should be caused by the transient faults, such as electromagnetic interference (EMI), unexpected power-off and burst software error. The transient faults recovery and safety control are aroused. Considering the transient faults come from the whole network, in this paper a three layers fault handling mechanism was proposed. The hardware logic was adjusted in the chip layer, the technology of retransmission and frequ...
Keywords:Wireless Sensor Network  Communication  Transient faults  Fault Recovery
