基于本体的传感器网络信息共享研究

摘要

The difficulty of “information sharing”, “information reusing” issue happend in Wireless Sensor Network is due to the heterogeneity of the application environment, data processing, communication protocol etc. Based on the introduction of the Ontolog theory, analyzing the sensor characteristic, a general type of sensor ontology contains the definition of concept, frame structure and OWL design was proposed from the standpoint of sensor observation. The paper expounded a system framework of the domain ontology through the expansion of knowledge base on the general sensor could achieve the information sharing and reuse by semantic communication between the general sensor ontology, the general sensor ontology and user. The research of this method would bring new idea to the semantic sensor network construction.%在无线传感器网络中，由于应用环境、数据处理、通信协议等方面的异构性，使得网络存在“信息共享、重用困难”的问题。本文通过引入本体思想，分析传感器特性，从传感器观测角度出发，阐述传感器本体含义、特点及构成，设计了一种通用的传感器本体，并论述了以此本体为基础进行知识扩展形成的领域本体通过传感器本体之间、传感器本体和用户之间的语义互操作实现信息共享和重用的系统框架。该方法的研究将为语义传感器网络建设提供新的思路。
