Abstract

The invention relates to a farmland sensor network multi-antenna-array transmission subarea node energy balance dispatching method. The farmland sensor network multi-antenna-array transmission subarea node energy balance dispatching method comprises the steps that a target monitored area is divided into multiple congruent figures to be used as multiple subareas; the collaborative center of each subarea is selected according to the types of nodes in the subarea and the distances between the nodes and the center of the subarea; other non-collaborative centers are added to the collaborative centers according to the positions, energy and other factors, so that multiple groups are formed; the data forwarding paths are selected between the groups according to the energy and position conditions of the collaborative centers; in each group, energy consumption balance is achieved by adopting a method for alternation of the collaborative centers in blocks, a method for multiple-node collaborative data transmission and other methods. By the adoption of the farmland sensor network multi-antenna-array transmission subarea node energy balance dispatching method, in a hybrid power supply wireless sensor network considering the energy demand and the cost demand, limited energy of non-renewable energy nodes are saved and equalized, and the effects of efficiently utilizing renewable energy and prolonging the service life of the network are achieved.

Description

technical field [0001] The invention relates to the technical field of energy scheduling, in particular to an energy balance scheduling method for multi-antenna array transmission partition nodes of a farmland sensor network. Background technique [0002] The deployment of wireless sensor networks in farmland can facilitate real-time data monitoring of large-scale farmland environments, and provide real-time information and guidance for production activities for agricultural production. At the same time, considering the energy demand of farmland environment wireless sensor network and the convenience of farmland environment to obtain renewable energy, the introduction of renewable energy nodes in wireless sensor network can meet the energy demand of the network. [0003] However, for a homogeneous wireless sensor network, in the prior art, the wireless sensor network will be stronger in terms of reducing energy consumption and improving network performance through mutual coo...
