摘要
无线网络技术的发展和嵌入式计算机的性能的提高,使得普适计算终端设备具有越来越好的计算性能。但大多数的普适计算终端设备对上下文情境计算能力依然不强,原因是普适终端还缺乏良好的情境模型表达能力、设备行为描述能力和推理运算机制,因而不能动态地根据上下文情境调整设备行为。本文给出了一种面向普适终端的上下文情境建模方法和终端行为描述方法,并给出两者之间的影射关系。本文还根据模型设计了一种基于上下文情境计算的系统框架。
Following the technology＇s development of the wireless network and the embedding computer, the pervasive devices have the higher and higher capability.But the most devices are still deficiency on context-aware computing.That＇s because the devices have not the good representation methods for contexts modeling and device behaviors modeling.The mechanism for these two models is absence, too.So the devices can not dynamically adjust their behaviors according to specific contexts.In this paper, we give an ontological model for context and device behaviors for pervasive computing environment, and these two models （context model and behaviors model） are connected with some logical relationships.A context-aware computing system is designed in this paper for illustration our models.
