摘要
研究环绕智能环境中的智能家庭网络结构,提出建立在应用服务层之上的环境感知知识库和基于软件无线电的自适应物理层研究思路。环境感知知识库包含网络以及用户的自身的、社会的以及精神等环境信息,提出基于Agent的主动移动数据库系统模型实现。基础网络层模型,提出结合软件无线电的思想,自适应控制物理层获悉的参数请求,优化物理层性能,对于智能终端设备及时感应自身以及与用户相关的环境信息,该思路突破了传统的OSI网络标准物理层及链路层的思路。
The architecture of the smart home network in ambient intelligence is described and the idea which includes the context knowledge base built upon the application service and the adaptable physical layer is presented. The context knowledge base contains user's physical, social, and psychological environment information, and its realizable model of the active-mobile database based on smart agent is proved in our paper. In infrastructure network, the adaptable physical layer incorporate software radio enables a wireless application to the better react to changing channel conditions and wireless applications to the proactively optimize physical layer performance using some application-defined set of metrics. This creative theory is different from OSI network standards.
