Embodiment Construction

[0050] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0051] The present invention provides a low power consumption method for extending a wireless sensor network from two dimensions of time and space, which will be described in detail below;

[0052] (1) Formalization of the problem; this part provides mathematical expressions for further processing of sensing data through the formal modeling of wireless sensor network deployment;

[0053] The predecessors paid more attention to how to design efficient network protocols or solutions to meet the potential demands of large-scale wireless sensor networks, while the work of the present invention focuses more on expanding the scale of wireless sensor networks from the data level. Without loss of generality, with CO 2 The gas propagation process is taken as the research object, and the application scenario is formalized as follows: record a given area to be measured a...

Abstract

The invention provides a low power consumption method for space-time double-dimension expansion of a wireless sensor network, the method is mainly improved by comprising the following steps: step S1,through formal modeling for network deployment of the wireless sensor network, providing formulation for further processing of sensor data; step S2, by application of a compressed sensing theory, customizing presentation and usage modes of a measuring matrix and a presentation matrix respectively in a one-dimensional space and a two-dimensional space, getting ready for performing original sensor data restoration by a restoration algorithm; step S3, restoring original sensor data through the restoration algorithm. The method provided by the invention restores the original sensor data at a highprobability through a small amount of data.

Description

technical field [0001] Wireless self-organizing sensor networks are not only very active in the research field, but also have many applications in the industrial and consumer fields, such as environmental monitoring, emergency warning, and structured monitoring. The invention belongs to the field of wireless self-organizing sensor networks, in particular to a theoretical method for wireless sensor network deployment. Background technique [0002] From small-scale test platforms in laboratories to medium-scale indoor deployments such as MoteLab and Kansei, to large-scale outdoor deployments in recent years, the scale of wireless sensor networks has been greatly expanded. Among them, VigilNet includes 200 nodes for long-term military monitoring, Trio implements a solar-powered wireless sensor network with 557 nodes, GreenOrbs is a forest monitoring system with 330 nodes deployed in the field, and CitySee is a A wireless sensor system deployed in an urban environment for real-...
