Embodiment Construction

[0023] 1. Architecture

[0024] figure 2 It is a context-aware model based on mobile agent, which consists of six parts: data source, context acquisition, context modeling, context fusion, intelligent executive and mobile agent platform.

[0025] A few specific parts are described below:

[0026] Data sources: In the ubiquitous computing environment, there are a wide range of data sources, and the data sources are characterized by distribution and heterogeneity. It mainly includes relational databases, sensor networks, and various other sensing devices. For different data sources, the acquisition of context information corresponds to different methods. This method uses JDBC (Java Data Base Connectivity, a Java API for connecting to the database) to access the relational database, and for different sensing devices, obtains the collected data by loading corresponding drivers. At the same time, in order to effectively perform data query and fusion processing in a pervasive c...

Abstract

The invention relates to a method for apperceiving context based on a mobile agency, which utilizes mobile agency technology to apperceive the context; context information is obtained, modeled, stored and utilized through the mobile agency; the method has applicability, intelligence and reusability; the method comprises the following specific steps: a, when a system is initialized, a mobile agency platform dispatches an executive body agency to an intelligent executive body layer and dispatches an evolution agency to a context modeling layer respectively; b, when a user inquires the context information or customizes a system, the mobile agency platform dispatches an inquiry agency or a customization agency to a context obtaining layer; c, the inquiry agency or the customization agency accesses corresponding data source according to the type of the context information; and a relational database is accessed through a JDBC interface; d, the evolution agency is combined with a reasoning engine, uses ontology reasoning to remove inconsistency of an original context and is mapped to an ontology library; and e, the executive body agency processes the received data and selects a proper mode to provide service for the user through self-adaptation, self-organization and other strategies.

Description

technical field [0001] The present invention proposes a context-aware method based on a mobile agent (mobile agent) in a pervasive computing environment, utilizes mobile agent technology, adopts a clustering mechanism and agent ideas, and provides an effective method for perceiving context in a pervasive computing environment. The method belongs to the field of ubiquitous computing. Background technique [0002] Ubiquitous computing is a human-centered computing model. Its essential feature is the fusion of information space and physical space. In this fusion space, people can transparently obtain digital services anytime and anywhere, and the computer itself will disappear from people's sight. , the center of people's attention can return to the task itself. In the ubiquitous computing environment, people will continuously and implicitly interact with different devices. During the interaction process, the computing system actually provides services to users according to co...
