【摘要】 普适计算已经成为一种全新的计算模式,但是目前对其模型的研究较少。本文试将普适计算环境以人为中心建模为一个"智能影子"模型。该模型建立在用户建模及普适服务抽象的基础上,通过用户BDP模型,将普适环境映射成一个以用户为中心的高度动态的虚拟个人空间,也称"智能影子",与物理世界的影子一样跟随用户,如影相随。智能影子模型在逻辑上简单自然,且可灵活处理普适计算空间的动态变化。我们还实现了一个仿真原型系统对模型的可行性进行了验证。更多还原

【Abstract】 Pervasive computing has become an emerging paradigm of computing, but currently there is little work addresses on pervasive computing model. This paper attempts to model pervasive computing environments as a user-centric "SmartShadow" using the BDP user model, which maps pervasive computing environments into a dynamic virtual user space. SmartShadow follows the user to provide him with pervasive services, just like people’s shadow in the physical world. The model is logically natural and simple, and can flexibly deal with dynamic changes of pervasive computing spaces. In addition, we implement a simulation system to verify and evaluate the SmartShadow model.更多还原
