利用Beta概率密度函数建立起普适计算环境下各个设备间轻量级的信任管理模型BTrust。通过源实体对目标实体直接服务结果的观察计算出直接信任服务值,并结合第三方实体的推荐服务值计算出目标实体服务的总信任值。加入的推荐信任的计算,给予不同的第三方实体推荐服务信任值不同的权重。该模型建立起设备间的信任关系,提高了服务成功率,并运用过滤机制抵制恶意推荐。仿真结果表明,该模型同时解决了该环境下小型设备的资源受限问题。 相似文献

智能影子(SmartShadow):一个普适计算模型 总被引:1,自引:0,他引:1
普适计算是一种全新的计算模式,目前对普适计算建模的研究较少.尝试以用户为中心将普适计算环境建模为一个“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移动的虚拟个人空间,也称“智能影子”,与物理世界的影子一样跟随用户,如影相随.其中,用户BDP模型根据信念(belief)推理出用户意图(desire),并对普适服务的计算过程进行规划(plan).普适服务用来抽象信息空间中的计算资源,可被用户BDP组织,完成用户的意图,组织的过程即为智能影子的映射过程.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.另外,还实现了一个仿真原型系统,对模型的可行性进行了验证. 相似文献

At the Pervasive Technology Applied workshop (part of Pervasive 2006), practitioners and researchers discussed how to bridge the gap between academic research and the practical hurdles in pervasive technology. The wide range of submissions demonstrated the great potential of applied pervasive technologies. In the emerging discussions, participants highlighted the most important technical and cooperation issues. 相似文献

Security and Privacy in Pervasive Computing 总被引:2,自引:0,他引:2
In this issue's Works in Progress department, we have six projects. The first two projects address an individual's privacy concerns and preferences. The next entry discusses a project on data protection for electronic passports. The remaining three projects are investigating various types of privacy protection mechanisms for data collected in pervasive computing environments, by attestation services, and by voice recording systems. 相似文献

Raising people's awareness with environmental data and educational information does not necessarily trigger sufficient motivation to change their habits towards a more environmentally friendly and sustainable lifestyle. This article reports on two workshops at Pervasive 2008 and UbiComp 2008 that sought to develop a better understanding how to go beyond just informing and into motivating and encouraging action and change. Drawing on participatory culture, ubiquitous computing, and real-time information, participants discussed research and development of viable new design approaches and information interfaces that can strengthen our position to meet the targets of the Kyoto protocol, and contribute to the sustainability of a low-carbon future. 相似文献

This special issue samples the developing area of pervasive computing in transportation systems through four feature articles and the Spotlight department, which consists of two interviews and two short articles. These contributions were written by automotive industry and academic experts and provide a diversity of views on a range of topics. Although the contributions focus on intelligent vehicular transportation, the technologies discussed also have applications in other transportation systems. This article is part of a special issue on Intelligent Transportation. 相似文献

As computers become more pervasive, they become more personal. The ultimate pervasive computer would be as unique as the individual it serves. Unfortunately, consumer products are typically closed to protect the manufacturer's intellectual property - a policy choice that hampers user's ability to customize products to fit their unique environments. The chumby is a pervasive computing device and novel business model that were designed to explicitly enable hackers (or "lead consumers") to customize their experience and participate in the hardware intellectual property ecosystem through a unique end user license. The chumby ecosystem is architected such that sharing the product's engineering plans with end users doesn't adversely affect the product's commercial viability. Indeed, by exposing this "lens of engineering" to end users, Chumby Industries' customers actually add value to and help define the company's product. 相似文献

PerCom 2004's theme was the emergence of the pervasive computing and communications paradigm with the goal of providing computing and communication services all the time, everywhere. The featured research represented the advances in pervasive computing and communications, including wireless networks, mobile computing, distributed computing, and agent technologies that will help realize this goal. 相似文献

FollowMeLite:用于普适计算的轻量级中间件平台 总被引:2,自引:0,他引:2
普适计算的目标是让环境和计算资源紧密结合,以便更好地为人类服务。为达到这一目标,移动设备和嵌入式设备构成了环境中计算资源的重要组成部分。然而,由于移动设备和嵌入式设备的计算资源有限,网络连接的多样性和不稳定性以及软硬件的异构性,开发用于这些设备的上下文感知应用复杂并且费时,其根本原因是缺乏一个统一的平台支持。为解决这一问题,我们提出了一种用于普适计算的轻量级中间件平台,叫做FollowMeLite。FollowMeLite是整个FollowMe普适计算基础结构中的一部分。它构建在OSGi之上,集成了基于本体的上下文模型和基于工作流的应用模型以及用于适应多种网络连接的通讯服务。通过部署不同的组件模块,FollowMeLite可以方便的适用于多种应用环境。 相似文献

The increasing deployment of pervasive computing technologies in urban environments has inspired researchers to explore the intersections between physical, social, and digital domains. The multidisciplinary Just-for-Us project is developing a mobile Web service designed to facilitate new forms of interaction by adapting content to the user's physical and social context. 相似文献

Pervasive computing has great potential to improve healthcare, from enriching data collection and distribution to virtually bringing experts to an emergency site. This special issue samples this developing area through five theme articles that go beyond current applications to find a wider range of applicability. This article is part of a special issue on Healthcare. 相似文献
