AI Technical Summary

Problems solved by technology

In this algorithm, the node energy is balanced to avoid the black hole problem, but it will cause the path length between the two data aggregation points to be too long, increasing the data delay
[0007] All the previous data receipt algorithms put more emphasis on improving energy imbalance or data freshness, but did not consider the path cost of selecting two data points

Embodiment Construction

[0033] A kind of automatic deflation device for brine dry pipe will be described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0034] 1.1 Tree building stage: Based on the given number of sensors, the Pulin algorithm is used to organize the sensors into a topology based on the minimum spanning tree. Each sensor node perceives data in a certain sensing area and forwards the tree root for processing.

[0035] 1.2 Selection of data collection points: In the minimum spanning tree constructed, the base station plays the role of the root of the tree. The base station is responsible for selecting the node with the greatest benefit from the sensor node set as the candidate sink node, and the base station calculates the path length and communicates with The given path length is compared, if it is less than the given maximum length, the node will be used as a candidate node, and the minimum spanning tree will be rebuilt. By repeatedly performi...

Abstract

The invention discloses a data acquisition method based on wireless sensor network energy perception and path architecture of a movable sink node, and relates to the technical field of wireless sensornetworks. The method includes the steps: S1 tree building stage: sensing data in a specific sensing area by each sensor node, and transmitting the data to a base station serving as a tree root to process the data by the aid of a given number of sensors; S2 data acquisition point selection: selecting a node with a maximum benefit by the base station from a sensor node set in a built minimum spanning tree to serve as a candidate sink node, calculating a path length, comparing the calculated path length with a given path length, and repeatedly executing operation until a sink node set is acquired. By the aid of an EAPC algorithm, the algorithm helps CP to save energy and time, so that a data acquisition node with the highest burden can save energy, node energy is balanced, and the life cycleof a whole data network is prolonged.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a data collection method for wireless sensor network energy perception and path architecture based on mobile convergence nodes. Background technique [0002] Wireless sensor networks are widely used in various fields such as environmental monitoring, fire monitoring, smart home, health care and medical treatment. Wireless sensor networks are composed of a large number of sensor nodes. Each sensor node is powered by a battery, and the energy of the battery is limited. Yes, in order to save energy, many scholars have adopted various methods and measures to reduce the energy consumption of wireless sensors, such as coverage, data collection, etc. In the data collection of wireless sensor networks (WSN), many literatures are mainly researched in a specific area Deploy a large number of static sensor nodes and adopt a certain method to construct a path to transmit the...
