A data acquisition method based on static cluster head deployment of cellular mesh

Abstract

The invention relates to a data acquisition method based on static cluster head deployment of a cellular grid, which realizes full coverage of an area by deploying a high-efficiency static cluster head node of the cellular grid, and on the basis thereof, a heterogeneous static clustering network model is constructed, wherein the backbone network formed by the high-efficiency cluster head node undertakes the data transmission task of the mobile node. At the same time, a security hierarchy trust mechanism is designed, which can realize mutual monitoring between high-performance nodes and one-way monitoring from high-performance nodes to mobile nodes. By combining heterogeneous network model and hierarchical trust mechanism, the data transmission path of energy, distance and security multi-factor backbone network is finally constructed. The data collection method not only reduces the topology instability and energy consumption required to maintain stable links in intelligent medical scenarios, but also reduces the impact of malicious nodes on the stable transmission of data, and can ensure that the monitoring data of mobile nodes are collected to the data center safely and effectively.

Description

technical field [0001] The invention relates to the technical field of data collection, in particular to a data collection method based on static cluster head deployment of a cellular grid. Background technique [0002] The comprehensive intelligent medical scene is an extended mode of smart home, with larger space and fewer obstacles, and the main source of data is patients wearing real-time monitoring equipment. In this scenario, the monitored patients can be regarded as intelligent mobile nodes. While collecting patient data (physiology, posture), these nodes also have the functions of aggregation, forwarding and management. Effective data established between nodes The transmission path will send the perception information of all nodes in the network to the data center, and the center manager will implement corresponding measures based on the collected data. [0003] Compared with the original smart home model with mostly static nodes, the data acquisition objects in the...
