Network layer construction method and system of farmland hybrid power supply wireless sensor network

Abstract

The invention discloses a method for constructing network layers of wireless sensor networks. The method includes grouping acquisition nodes of the wireless sensor networks; enabling sink nodes to periodically receive node information of the acquisition nodes, acquiring weather forecast index information and constructing characteristic vectors of the acquisition nodes; selecting backbone nodes according to the characteristic vectors; selecting non-backbone nodes from the acquisition nodes according to the backbone nodes, and grading the non-backbone nodes according to the availability of the backbone nodes in communication ranges of the non-backbone nodes; constructing the network layers according to the backbone nodes and grades of the non-backbone nodes. The method has the advantages that characteristic information of the acquisition nodes and the weather forecast index information are periodically received by the sink nodes, the characteristic vectors of the acquisition nodes are constructed, a neural network with a decorrelation layer, an input layer and a competition layer is established, accordingly, sample learning can be carried out, the backbone nodes can be optimally selected, and energy consumption between the nodes can be reasonably distributed.

Description

technical field [0001] The invention relates to the technical field of wireless network communication, in particular to a method and system for constructing a network level of a farmland hybrid power supply wireless sensor network. Background technique [0002] In recent years, the utilization technology of green energy such as solar energy, wind energy and other renewable energy has gradually matured and perfected. Considering that there are abundant solar energy resources in the farmland environment, using solar energy to supply power to wireless sensor nodes can solve the problem of energy limitation of farmland wireless sensor networks and promote the wide application of wireless sensor networks in farmland. However, compared with ordinary battery power supply, solar power supply requires additional modules such as solar panels and batteries, so its cost is higher and the installation is more complicated, and the installation of solar panels in farmland will have a certa...
