Problems solved by technology

Energy replenishment is generally charged by a mobile charging device. The charging device can charge it after being close to the node, or it can be charged over a long distance, but the energy loss of long-distance charging is relatively large, and the stability is poor.

Embodiment 1

[0045] Embodiment 1: as Figure 1-4 As shown, a mobile energy supplement method based on hierarchical structure in a virtual backbone network environment divides the wireless sensor network into a backbone node layer and a common node layer. The backbone node layer is responsible for relaying the information sensed by the common node layer to the base station. Due to the high energy consumption of information transmission, the load of the node layer of the backbone layer is also relatively large. During the entire charging process, the backbone node layer is given priority to replenishing energy.

[0046] Specifically include the following steps:

[0047] Step 1. Divide the wireless sensor network into a backbone node layer and a common node layer by constructing a backbone network according to the difference in energy consumption. The specific steps for realizing this division are as follows:

[0048] Step1.1, find the maximum independent set (MIS), in graph G=(v 1 ,v 2 ...

Abstract

The invention discloses a mobile energy replenishment method based on a hierarchical structure in a virtual backbone network environment, and belongs to the technical field of wireless sensor networks. In wireless sensor networks, the energy limitation of sensor nodes seriously restricts the performance of the network, and the existing energy replenishment methods are almost all based on planar structures, which cannot effectively describe the sensor nodes in the network due to the difference in energy consumption. hierarchical issues. The invention divides the sensor nodes in the network into a backbone node layer and a common node layer according to the difference in energy consumption, corresponding to sensor nodes with high energy consumption and sensor nodes with low energy consumption respectively. And give priority to replenishing energy for the backbone node layer while taking into account the energy replenishment of the ordinary node layer. Effectively avoid node failure due to energy exhaustion. The invention provides a new solution for the hierarchical structure-based wireless sensor network in the virtual backbone network environment, and realizes the long life cycle and sustainable operation of the network.

Description

technical field [0001] The invention relates to a mobile energy replenishment method based on a hierarchical structure in a virtual backbone network environment, and belongs to the technical field of wireless rechargeable sensor networks. Background technique [0002] The wireless sensor network is composed of a large number of sensor nodes. The sensor nodes in the network can collect the network environment information within its sensing radius, and aggregate the collected information. After processing, the information is sent to the base station node through multi-hop. , and then the base station uploads the information to the network for user analysis and use. However, wireless sensor nodes are powered by their own batteries, which are limited by volume, cost, battery capacity and other technologies, which means that nodes in the network may fail at any time due to insufficient energy, resulting in network interruption, data loss, and node perception. Coverage hole, even...
