Abstract

In wireless sensor network, the storage amount of information is high, and the transmission and scheduling of control information is reasonable. The node communication model, network structure model, and energy consumption model are constructed. On this basis, the high-density data in wireless sensor network are scheduled to optimize the time for nodes to perform tasks. The nodes in the network are fully scheduled to control the generation time of packets in the network and the generation time of packets in the network. Experimental results show that in different iterations, the proposed method has lower node delay and node energy consumption, with values less than 0.2 and 2, respectively, and the maximum data fusion quality can reach 98, with high fusion benefits, so as to improve the transmission and scheduling efficiency and quality of high-density data in wireless sensor network.

Highlights

The rapid development of technologies and theories such as microelectronics, computers, embedded computing, communications, control, and radio frequency identification has led to the significant increase in the focus on the Internet of things in industry, academia, and governments.[1,2] The Internet of things is the future direction of the network, and it is the focus of the world information industry after the mobile communication network, the Internet, and computers
The main function of wireless sensor network is to collect and transmit data, so the transmission and scheduling of data is the key problem of wireless sensor network
The current data transmission scheduling method has the problems of high node delay, high node energy consumption, and low fusion benefit

Summary

Introduction

The rapid development of technologies and theories such as microelectronics, computers, embedded computing, communications, control, and radio frequency identification has led to the significant increase in the focus on the Internet of things in industry, academia, and governments.[1,2] The Internet of things is the future direction of the network, and it is the focus of the world information industry after the mobile communication network, the Internet, and computers. The Internet of things is the information carrier obtained on the basis of the traditional telecommunication network It can realize the interconnection and interconnection between ordinary independent physical objects and has three characteristics of intelligence, interconnection, and equipment.[2,3] The Internet of things has been widely used in agriculture, defense and military, industrial manufacturing, logistics economy, health care, ecological and environmental protection, power grid, and food safety.[3,4] Its terminal network is the wireless sensor network, which provides the way to perceive the world of the Internet of things in a large space–time scale.[5] Nodes have energy-limited phenomena in the network, and the main way to consume energy is data transmission. It is necessary to study the data transmission scheduling method
