A Data Acquisition Method Based on Cellular Grid Static Cluster Head Deployment

Abstract

The present invention relates to a data acquisition method based on static cluster head deployment of cellular grids, which deploys high-efficiency static cluster head nodes through cellular grids to achieve full coverage of the area, and builds a heterogeneous static clustering network model based on the high-efficiency The backbone network formed by the cluster head nodes undertakes the data transmission task of the mobile nodes; at the same time, a security level trust mechanism is designed, which can realize mutual monitoring between high-performance nodes and one-way monitoring from high-performance nodes to mobile nodes. Combining the heterogeneous network model and the hierarchical trust mechanism, the construction of the data transmission path of the backbone network that integrates energy, distance, and security factors is finally completed. This data collection method not only reduces the instability of the topology and the energy consumption required to maintain a stable link in intelligent medical scenarios, but also reduces the impact of malicious nodes on the stable transmission of data, which can ensure that the monitoring data of mobile nodes are safely and effectively collected in the data center.

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...
