Problems solved by technology

[0005] The problem to be solved by the present invention is: Aiming at the characteristics of the large scale of the Internet of Things and the fragile performance of network nodes, a layered network architecture is proposed, and the energy consumption constraints caused by nodes sending data under this architecture are comprehensively studied. Constraints, link maximum transmission rate constraints, system budget constraints, and network lifetime evaluation criteria solve the problem that the overall performance of the network cannot be optimal due to the traditional simple research on energy consumption or lifetime or a combination of the two, and proposes a A static routing optimization algorithm suitable for the Internet of Things, which solves the problem of excessive energy loss in the Internet of Things technology, and avoids factors such as electromagnetic interference, air humidity, and temperature that cause the dynamic routing mechanism to be unsuitable for large-scale Internet of Things

Embodiment Construction

[0011] First, we give a simplified description of the IoT network model as follows without loss of generality:

[0012] 1) Use x and y to represent two points in the Euclidean plane, and use d(x,y) to represent the distance between the two points;

[0013] 2) Use the set S={SN 1 ,SN 2 ,...,SN l} represents a given l SN (sensor node) distributed in a two-dimensional plane, and its communication radius is recorded as r>0;

[0014] 3) Use the set χ={RN 1 ,RN 2 ,…,RN m} represents m RNs (relay nodes) distributed on a two-dimensional plane, and its communication radius is recorded as R≥r;

[0015] 4) Use the set B={BS 1 ,BS 2 ,...,BS n} represents n BSs (base stations) distributed on a two-dimensional plane, which means that two base stations can communicate with each other.

[0016] The network model proposed by the present invention will be specifically described below with reference to the accompanying drawings.

[0017] figure 1 Shown is the three-layer network topo...

Abstract

The invention discloses a building and energy-saving deployment method of a network model based on internet of things and belongs to the field of internet of things communication technologies. The invention provides a three-layer network framework and network energy consumption optimization model based on the internet of things. The energy-saving deployment method includes the steps: firstly, eliminating alternative relay nodes which cannot communicate with any sensor node according to the distance between the sensor nodes and the alternative relay nodes, then choosing i relay nodes in the rest of the relay nodes, equating the sum of sending energy consumption of sending nodes in each section of link and receiving energy consumption of receiving nodes in each section of link with a weight of the section of link when the i relay nodes meet the condition that whether topology which is formed by all standing sensor nodes and a station is a connected graph, obtaining a minimum value of energy consumption and survival time of a network in an improved Dijkstra method, and taking the network node deployment method under the energy consumption as an optical energy-saving deploy method.

Description

technical field [0001] The invention relates to the technical field of Internet of Things communication, and in particular aims at establishing network models and energy-saving deployment strategies based on Internet of Things technology. Background technique [0002] With the rapid development of communication technology, people are no longer satisfied with communication methods that require people to participate in interactions between people and people. A smarter and more convenient communication method is expected by people. The Internet of Things --- a communication method that can complete information interaction between objects and machines without human participation came into being. The Internet of Things (Internet of Things) is an intelligent network that connects all objects together, using technologies and devices such as Radio-Frequency IDentification (Radio-Frequency IDentification), wireless communication, real-time positioning, video processing, and sensing t...
