Data management system for distributed heterogeneous sensing network and data management method for data management system

Abstract

The invention discloses a data management system for a distributed heterogeneous sensing network and a data management method for the data management system. The heterogeneous sensor network is subjected to data management by adopting a multi-layer architecture system, so that the whole sensing network is convenient and easy to arrange and adjust. Furthermore, the system performs distributed storage on data acquired by wireless sensor nodes, so that the bottleneck problem of concentrated data processing is solved, and the data processing efficiency is greatly improved. A large quantity of data acquired by data sensing nodes of a camera are quickly transmitted by a wireless local area network, so that an application requirement of a client on an image video can be met. The system supplies a high-efficiency data inquiry function and a real-time topological display function to a client; a requirement of the client for complicatedly processing the data acquired by the sensor nodes can be met; and a running state of the whole sensor network can be timely reflected to the client.

Description

technical field [0001] The invention relates to a sensor network data management system, specifically a distributed heterogeneous sensor network data management system and a data management method thereof, which are used for managing data collected by different types of sensor nodes. Background technique [0002] The sensor network is a data-centric network. It regards sensor nodes as sensory data streams or sources of sensory data, sensor networks as sensory data spaces or sensory databases, and data management content such as data query and data analysis as the entire sensor network. application target. Therefore, any sensor network-based application is inseparable from data collection, storage, query, analysis, and visualization, and data management has naturally become one of the core technologies of sensor networks. [0003] The core of sensor network data management is data storage and data query. At present, data storage is mainly divided into three types, ...

Problems solved by technology

In addition, because the data management system based on data flow focuses on basic data processing functions and system-level implementation, it is difficult to use it directly in specific wireless sensor network applications to obtain ideal results; while WiSeCoMaSys and SWAT are used in data collection, analysis and There are still imperfections in visualization, such as real-time display of network topology maps, sensor data query processing requests, etc.
