Embodiment Construction

[0061] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0062] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0063] The present invention first clusters the nodes in the network, wherein the selection of the cluster head needs to refer to factors such as the energy consumption speed of the node, the remaining energy and the distance between the node and the base station, and the calculation of the corresponding cluster radius comprehensively considers the cluster head node and the base station The distance between them and the density of their neighbor nodes, this clustering method can balanc...

Abstract

The invention discloses a mobile charging method based on clustering and energy relay in WSNs. The method comprise the following steps: firstly, nodes of the whole network are clustered, a cluster head is selected according to the energy consumption speed of the node, the residual energy and the distance from the base station node, and the corresponding cluster radius is computed, wherein the cluster head node is used as a resident point of the charger for performing energy transmission and data collection; secondly, the base station plans the corresponding charging path according to a charging request sent by the node, and dispatches a charger to charge the node; the node in the cluster performs the effective energy transmission through an energy relay way; when the nodes needs the emergency charging, the base station can determine the charger in response to a node emergency charging request. The charging process and the data collection process are combined, the data is divided into the sensitive data and insensitive data, and the different collection strategies are adopted. By using the mobile charging method disclosed by the invention, the energy consumption among the clusters in the network can be balanced, the charging validity and the network expandability are improved, thereby maximizing the network life.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor network node energy supplementation, in particular to a mobile charging method based on clustering and energy relay in WSNs. Background technique [0002] Energy problem is one of the main factors restricting the application of wireless sensor network. Generally, the nodes in wireless sensor networks are powered by batteries, and the limited battery capacity of nodes seriously affects the life cycle of the network. [0003] In recent years, relevant personnel have done a lot of research on optimizing the battery life of nodes and prolonging the life of the network. The research work is mainly divided into two aspects: reducing energy consumption of nodes and supplying energy to nodes. Among them, reducing the energy consumption of nodes is mainly to extend the survival time of nodes as much as possible by reducing the overhead of nodes in daily perception and communication, as well as res...
