Abstract

The invention discloses a fault diagnosis device and method for a wireless sensor network (WSN). The fault diagnosis device includes a diagnosis trigger unit, a fusion tree building unit, a diagnosis evidence generating unit, a diagnosis evidence fusion unit and a fault diagnosis unit. Corresponding fusion trees are automatically built for different faults, and fused fault diagnosis is then carried out in local problem areas. Compared with the traditional fault diagnosis method for the WSN, the invention solves the problems of the traditional fault diagnosis method for the WSN such as large diagnosis expenses, unavailability of real-time diagnosis, inaccurate status acquisition of local problem areas and the like, achieves local real-time fault diagnosis for the WSN, and has the advantages of rapidness in diagnosis, high diagnosis accuracy and good expandability.

Description

technical field [0001] The invention relates to the field of wireless sensor networks, in particular to a wireless sensor network fault diagnosis device and method. Background technique [0002] With the rapid development and maturity of communication technology, sensor technology and embedded computing technology, wireless sensor networks are widely used in environmental monitoring, coal mine accident detection, dangerous situation navigation, traffic flow monitoring and many other scenarios that are closely related to the national economy and people's livelihood. . Due to the limitations of the current technological level and manufacturing process, the software and hardware of sensor nodes (referred to as nodes) usually do not work perfectly, and are generally error-prone. At the same time, due to the use of wireless signals for data transmission between nodes, factors such as multi-path (multi-path) and interference (interference) further increase the instability of wire...
