Abstract

Embodiments of the invention disclose a fault detection method and a fault detection device for a wireless sensor network. The method comprises the following steps: acquiring a system parameter value sequence of any two system parameters contained in each sensor node in a current time window; sorting the system parameter values, and acquiring a system parameter value ordered sequence for each sensor node; calculating out the relation value view vector of each sensor node; clustering all the relation value view vectors in the current time window to get a clustering result; and determining the sensor nodes corresponding to the relation value view vectors not belonging to the clustering result in the current time window as faulty nodes. According to the embodiments of the invention, the relation between the system parameters of sensor nodes is utilized, and the problem on how to detect faults in a wireless sensor network based on the relation between the system parameters of sensor nodes is solved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a fault detection method and device for a wireless sensor network. Background technique [0002] Wireless Sensor Networks (WSN for short) is a distributed sensor network whose ends are sensors that can perceive and inspect the outside world. The sensors in the WSN communicate wirelessly, so the network setting is flexible, the location of the device can be changed at any time, and it can also be connected to the Internet in a wired or wireless manner. A multi-hop self-organizing network formed by wireless communication. [0003] Usually, a wireless sensor network is composed of a large number of sensor nodes with low cost and limited power. Since the sensor nodes are distributed in harsh and uncontrollable environments, the sensor nodes are prone to failure, which leads to the failure of the wireless sensor network. [0004] At present, for fault detection of wir...
