Embodiment Construction

[0037] The preferred embodiments will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0038] figure 1 It is a schematic diagram of the application scene of the present invention. figure 1 Among them, a typical wireless network sensor includes at least one management server (herein referred to as the management terminal) and several nodes (wireless network sensors). At a certain time T, node B finds that its data throughput rate has decreased abnormally, and the degree is serious, which seriously affects the network function. It diagnoses this event as a fatal failure level and sends a request to the server to dispatch a mobile fault agent. After receiving the node's request, the server queries the previous similar fault handling method in the fault handling experience log, and sends the corresponding ...

Abstract

The invention discloses a wireless sensor network fault processing method in the technical field of wireless communication. The method comprises the following steps of: after a server is started, starting a monitoring process to monitor fault alarm information; after a node is started, sending a start message to the server; maintaining a node information sheet by using the server according to the start message sent by the node; and judging whether the node per se has a fault by using the node, and if the node per se has the fault, judging a fault level by using the node and performing corresponding processing according to the fault level. Due to the adoption of the method, the communication efficiency of a network is ensured and the hardware resource of the node is improved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a processing method for a wireless sensor network failure. Background technique [0002] In recent years, with the continuous progress of microelectronics technology and communication technology, sensor nodes are gradually developing in the direction of miniaturization and intelligence. The network composed of these small and cheap sensor nodes can effectively perceive the physical world with its ubiquitous sensing and computing characteristics, which further improves the ability of human beings to obtain objective information, and is widely used in military, environmental monitoring, It has important research value and application prospects in many fields such as smart home, building monitoring and medical care. [0003] The wireless sensor network collects the surrounding environment information through the sensor nodes deployed in the monitoring are...
