Abstract

The invention discloses a wireless sensor network monitoring method and system based on compressed sensing. The method includes: defining the spatial correlation of deployed sensor nodes in a region to be monitored and obtaining a compressed sensing observation matrix of a wireless sensor network constituted by the sensor nods; and obtaining the theory monitoring data of the region to be monitored according to the actual monitoring data of the sensor nodes and the compressed sensing observation matrix. The wireless sensor network monitoring method and system based on the compressed sensing can reduce the deployment number and difficulty of the sensor network, effectively avoids datagram congestion and data loss of the wireless sensor network, and improves the monitoring accuracy and reliability of the wireless sensor network.

Description

technical field [0001] The invention relates to the technical field of wireless sensors, in particular to a wireless sensor network monitoring method and system based on compressed sensing. Background technique [0002] With the rapid development and maturity of wireless 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. middle. [0003] In these scenarios, in order to cover the ideal area and ensure the accuracy of data collection, it is often necessary to deploy a large number of sensor nodes. However, the dense deployment of sensor nodes not only consumes a lot of cost and human and material resources, but also has congestion and management difficulties in the sensor network, and even leads to...
