Method for node placement of Internet of Things

Abstract

The invention relates to a method for node placement of the Internet of things. The method comprises the steps of establishing a square basic monitoring area model, calculating the area of the basic monitoring area model and comparing the area of the basic monitoring area model with the area which actually needs to be monitored, establishing a novel square basic monitoring area model and calculating the area of the novel square basic monitoring area model, determining the multiple relation of the area of the novel square basic monitoring area and the area which actually needs to be monitored, determining the relations of the number of nodes of a total sensor, the distance of two adjacent sensor nodes on diagonal lines, a topological hierachy number, the number of cluster head nodes and the area which actually needs to be monitored, actually choosing and arranging a monitored area, choosing a topological structure which can represent the whole terrain configuration, configuring the dynamic-static combination routing mechanism of the whole monitoring area, and when the monitoring area needs to be expanded, the monitoring area is combined or a plurality of circles of basic monitoring areas is added on the outermost layer of the monitoring area. The method can be widely used for the node displacement of the Internet of Things.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a method for deploying nodes of the Internet of Things oriented to large-scale monitoring. Background technique [0002] The Internet of Things (Internet of Things) is a hot technology that has a major impact on human production methods in the 21st century, and is a new field in information technology. Because of its high precision, strong real-time performance, flexible deployment of nodes and no need for human intervention, the sensing part can be integrated with various current transmission backbone networks such as GPRS, 3G, satellite communication, wireless communication, microwave and China's Beidou satellite navigation system. The combination of SMS communication and other advantages is very suitable for monitoring in large-scale, long-distance, and harsh environments. In the application process of the Internet of Things, how to effectively deploy sensor no...

Problems solved by technology

This can ensure the uniform distribution of nodes, which is conducive to ensuring the accuracy of monitoring data, but the nodes placed at the vertices of the graph are also the disadvantages of these two deployment methods: when the sensor nodes are networked in a cluster structure, the clusters close to the coordinator The energy consumption of the head is heavy, while the energy consumption of the cluster head far away from the coordinator is light, so the cluster head node will have an important impact on the performance of the network

However, in the current deployment methods using these two graphs, the placement of cluster head nodes is not well considered. How to combine the uniformity of the cluster structure with energy saving and scalability is an important problem currently facing

In practical applications, it is often easy to know information such as the transmission radius of sensor nodes and the area of ​​the monitoring area, but there is currently no good way to quickly determine the scale of the monitoring area network and the required topology based on these two pieces of information. The number of layers and the number of sensor nodes, and this information has an important guiding role in the actual investment
