A Construction Method of Heterogeneous Node Meta-model of Sensor Network

Abstract

The invention relates to the technical field of wisdom city geographic information service and particularly relates to a construction method of a sensor network heterogeneous node element model. The construction method of the sensor network heterogeneous node element model solves the problem that an existing sensor network heterogeneous node is lack of effective description means and information models are not uniform, the sensor network heterogeneous node element model is constructed, five kinds of metadata construction members and a node information description framework of a nine-tuples structure are provided, and metadata elements of heterogeneous node information are extended. Compared with an existing sensor network resource information model and a management mode, content of the sensor network heterogeneous node element model comprehensively describes metadata information of the heterogeneous node, and the construction method of the sensor network heterogeneous node element model provides a universal meta-model framework and modeling standard for information description of the heterogeneous node, provides support for unified management and accurate find of the heterogeneous node, and is proved to be a practical and reliable method favorable for heterogeneous node modeling in sensor network resource management.

Description

technical field [0001] The invention relates to the technical field of smart city geographic information services, in particular to a method for constructing a sensor network heterogeneous node meta-model. Background technique [0002] The sensor network is a new method in the field of earth observation, which integrates distributed resources into a dynamically adaptive, reconfigurable and configurable collaborative observation network. As a complex observation system, the sensor network has large-scale, different functions, and dynamically distributed network node resources. How to integrate, manage and share the heterogeneous nodes of the sensor network is a huge challenge. Building a sensor network heterogeneous node information model based on the node meta-model is of great significance for the sharing and interoperability of sensor network resources. Requirements for sensor network resource configuration and architecture design under land surface monitoring and emergen...

Problems solved by technology

[0008] (1) For the different types, different structures, different working methods and input and output of heterogeneous nodes in the sensor network, there is currently no modeling mechanism that can comprehensively and effectively express the information of heterogeneous nodes, and there is still a lack of a complete description Node information and a node metadata model that reflects its differences, to expand metadata for node heterogeneity on the basis of the node public attribute structure;

[0009] (2) For the information description of sensor network nodes, there are currently only relatively independent information models and metadata standards involving sensors, observation platforms, processing algorithms, and application services. The modeling objects are single and the methods are different, and the metadata information is incomplete. Not specific, there is still a lack of a standardized and standardized modeling method and tool, and it is impossible to systematically describe the heterogeneous nodes of the sensor network under a unified framework
