We here illustrate a new indoor navigation system. It is an outcome of creativity, which merges an imaginative scenario and new technologies. The system intends to guide a person in unknown building by relying on technologies which do not depend on infrastructures. The system includes two key components, namely positioning and path planning. Positioning is based on geomagnetic fields, and it overcomes the several limits of WIFI and Bluetooth, etc. Path planning is based on a new and optimized Ant Colony algorithm, called Ant Colony Optimization (ACO), which offers better performances than the classic A* algorithms. The paper illustrates the logic and the architecture of the system, and also presents experimental results.

The aging population is an important trend of global population development in this century, and its influence reaches far and wide. Taiwan society is also affected by this global trend of aging, so industries should understand and adapt to this trend for the sake of survival. Moreover, the aging of populations around the world will bring enormous impact and change to the social system, lifestyle, business and economic model, and various industries. In order to sustain industrial development, more effort should be made to understand the influence of aging on industrial development trends. The aim of this essay is to discuss the influence of Taiwan's aging population on the design industry, thereby finding out how Taiwan's design industry should cope with the aging population.

Service-Oriented Multi-tenancy (SO-MT): Enabling Multi-tenancy for Existing Service Composition Engines with Docker 面向服务的多租户(SO-MT):使用Docker为现有的服务组合引擎启用多租户

In Web Services-based SOAs, BPEL 2.0 is the choice for defining services by composing existing ones. BPEL-based services can be directly executed on BPEL engines. With the rise of the cloud, companies aim to outsource service hosting to cloud providers. To achieve economies of scale, a cloud provider must host such services with minimal resources and keep the services from different tenants isolated. But BPEL engines typically do not support multi-tenancy. As a result, a vendor either has to extend the engine himself or host every service on its own (virtual) machine, thereby using either costly development or computing resources. Our approach solves this problem by hosting each service in its own isolated and minimal container which exposes the management functionality through APIs enabling complex multi-tenancy features or horizontal scaling on top. We aim to implement this by a) leveraging Docker container to isolate the services from each other, b) removing unused software from the container, c) starting the BPEL engine with minimal resources, and d) extracting management functionality while keeping management APIs. Our case study with Apache ODE shows that we can save significant runtime resources with only minor development effort. While this approach helps in moving SOAs into the cloud, it can also be leveraged to build resource efficient BPEL-based microservices cheaper.
在基于Web服务的soa中,BPEL 2.0是通过组合现有服务来定义服务的选择。基于BPEL的服务可以直接在BPEL引擎上执行。随着云计算的兴起,公司的目标是将服务托管外包给云提供商。为了实现规模经济,云提供商必须用最少的资源托管这些服务,并保持来自不同租户的服务隔离。但是BPEL引擎通常不支持多租户。因此,供应商要么必须自己扩展引擎,要么在自己的(虚拟)机器上托管每个服务,从而使用昂贵的开发或计算资源。我们的方法解决了这个问题,将每个服务托管在自己独立的最小容器中,通过api公开管理功能,支持复杂的多租户特性或在顶部进行水平扩展。我们的目标是通过a)利用Docker容器来隔离彼此之间的服务,b)从容器中删除未使用的软件,c)用最少的资源启动BPEL引擎,以及d)在保留管理api的同时提取管理功能来实现这一点。我们对Apache ODE的案例研究表明,我们只需要少量的开发工作就可以节省大量的运行时资源。虽然这种方法有助于将soa迁移到云中,但也可以利用它来构建更便宜的资源高效的基于bpel的微服务。

Trust Modeling in Cloud Computing 云计算中的信任建模
Pub Date : 2016-03-01 DOI: 10.1109/SOSE.2016.32

Though, cloud computing continues to gain popularity and has enormous economic gains, the perceived lack of trust from end-users accessing these resources continues to hinder its full deployment, usage and adoption. Tradition security and privacy controls continue to be implemented on cloud but due to its fluid and dynamic nature, research work in the area of end-user attestable trust evaluation of the cloud platform seem to be limited. With the nature of cloud, service level agreements are not enough, the user would want a transparent system with a traceability facility that allows the user to determine the relationship between varying trust relationships across the cloud layers, components, algorithms and applications especially at large scale. This paper presents some security mechanisms that enable cloud service end users to evaluate the trust level of various cloud services and resources. These mechanisms are evaluated based on fuzzy theory on a Eucalyptus cloud platform.
尽管云计算不断普及,并带来巨大的经济收益,但访问这些资源的最终用户缺乏信任,这继续阻碍着云计算的全面部署、使用和采用。传统的安全和隐私控制继续在云上实施,但由于其流动性和动态性,云平台的最终用户可证明信任评估领域的研究工作似乎有限。由于云的性质,服务级别协议是不够的,用户需要一个透明的系统,具有可追溯性设施,允许用户确定跨云层、组件、算法和应用程序之间的不同信任关系之间的关系,特别是在大规模的情况下。本文提出了一些安全机制,使云服务最终用户能够评估各种云服务和资源的信任级别。在一个桉树云平台上,基于模糊理论对这些机制进行了评价。

IoT (Internet of Things) is changing the world. Today, we see that the Internet is reaching every bit in the world. IoT environment contains mobile devices, automotive equipments, and home appliances. Everything is sensed, actuated, and integrated into the Internet. Accordingly, the related problems are fast emerging. Considering the fact that the IoT is closely connected to human activities, and that the problems essential to them are tangled with traditional technical problems, it is quite natural that new challenges emerge there. Device control and privacy related security problems are their typical concerns. On the other hand, continuous efforts have been made for establishing trust in the untrusted Internet. Particularly, since it became clear that mutual trust was essential to securely and trustfully expand the market of e-commerce in the Internet, a number of technical solutions have been proposed and deployed. Furthermore, a kind of social infrastructure - trust frameworks have been deployed and are operated as the trust anchors in the Internet. In our work, trust establishment in IoT environments is investigated along the line of the trust framework in identities. First, our IoT architecture is proposed. Control and data service layer is placed on top of the device layer and the wireless communications. Trust establishment on the service layer includes that of device control and wireless security. Here, we consider "area"-wise trust, where its level is assessed in terms of device identification, monitoring of device behaviors, connection process to devices and connection protocols that are parallel to the assessment criteria in the conventional trust framework. Secure mobile network as the anchor of IoT trust is also discussed.
物联网(IoT)正在改变世界。今天,我们看到互联网正在触及世界的每一个角落。物联网环境包括移动设备、汽车设备和家用电器。一切都被感知、驱动并集成到互联网中。因此,相关问题正在迅速出现。考虑到物联网与人类活动密切相关,其本质问题与传统技术问题纠缠在一起,自然会出现新的挑战。设备控制和与隐私相关的安全问题是他们典型的关注点。另一方面,人们不断努力在不受信任的互联网上建立信任。特别是,由于相互信任对安全可靠地扩大互联网上的电子商务市场至关重要,因此已经提出和部署了一些技术解决方案。此外,一种社会基础设施——信任框架已经被部署并作为信任锚点在互联网上运行。在我们的工作中,沿着身份信任框架的路线研究物联网环境中的信任建立。首先,提出了我们的物联网架构。控制和数据服务层位于设备层和无线通信层之上。服务层信任的建立包括设备控制信任和无线安全信任的建立。在这里,我们考虑“区域”智能信任,其级别根据设备识别、设备行为监控、设备连接过程和连接协议进行评估,这些与传统信任框架中的评估标准平行。安全移动网络作为物联网信任的锚点也进行了讨论。

An Approach for QoS-aware Selection of Shared Services for Multiple Service Choreographies 基于qos的多服务编排共享服务选择方法
Pub Date : 2016-03-01 DOI: 10.1109/SOSE.2016.62
J. C. Lima, R. Rocha, F. Costa
Choreographies represent a particular approach for service composition in which coordination is performed in a distributed way. This approach is becoming one of the de facto standards for service composition in the Future Internet. However, QoS-aware deployment and management of service choreographies is usually performed without explicitly considering service sharing. This simplifying assumption makes choreography deployment less feasible in real scenarios, in which individual services are actually shared by several choreographies. This paper presents an approach for QoS-aware service selection for multiple choreographies considering the sharing of services among them. In particular, we argue that sharing-aware service selection represents a more realistic perspective since unsupervised service sharing may degrade the overall QoS provided for the choreographies. Our approach for service selection avoids this degradation by taking into account, besides the QoS requirements of service consumers and the QoS properties of services, the aggregate service load that results from the sharing.
编排代表了服务组合的一种特殊方法,在这种方法中,协调以分布式方式执行。这种方法正在成为未来互联网中服务组合的事实上的标准之一。然而,服务编排的qos感知部署和管理通常在没有明确考虑服务共享的情况下执行。这种简化的假设使得编排部署在实际场景中不太可行,在实际场景中,单个服务实际上由几个编排共享。本文提出了一种考虑多个编排之间服务共享的qos感知服务选择方法。特别是,我们认为共享感知的服务选择代表了一种更现实的观点,因为无监督的服务共享可能会降低为编排提供的整体QoS。我们的服务选择方法避免了这种退化,除了考虑服务消费者的QoS需求和服务的QoS属性外,还考虑了共享产生的总服务负载。

Intermittent Data Dissemination Using Node Forwarding Capability Estimation in Vehicle Delay Tolerant Networks 基于节点转发能力估计的车辆容忍延迟网络间歇数据传播
Pub Date : 2016-03-01 DOI: 10.1109/SOSE.2016.12

Recently, both the vehicle active safety service and the user infotainment service have become two core applications for vehicular delay tolerant networks (VDTNs). Both the core applications over VDTNs demand a high data transmission capacity. Additionally, the connection between any vehicle nodes in VDTNs is intermittent and opportunistic. The intermittent data dissemination is a more stringent and challenging issue than the full connectivity vehicular ad-hoc networks (VANETs). In this paper, we propose a data dissemination algorithm using node forwarding capability estimation (D2NFCE). For the first step, D2NFCE has to estimate the active connection time interval according to the moving directions and the velocities between any two vehicles. Secondly, the throughput function for VDTNs is fitted by building the wavelet neural network traffic model. Next, the throughput function within the effective connection time interval is integrated to obtain the forwarding capability estimation of the node. And then, the high efficiency routing algorithm for VDTNs is designed by the node forwarding capability estimation. Finally, D2NFCE is simulated on the opportunity network emulator (ONE). Experimental results show that the D2NFCE can greatly improve data dissemination efficiency, reduce the transmission delay, delay jitter and data packet loss rate compared with the state of the art.
近年来,车辆主动安全服务和用户信息娱乐服务已成为车载容延迟网络的两大核心应用。这两种核心应用对vddn的数据传输能力都有很高的要求。此外,vddn中任何车辆节点之间的连接都是间歇性和机会性的。间歇性数据传播是一个比全连接车辆自组网(VANETs)更严格和更具挑战性的问题。本文提出了一种基于节点转发能力估计(D2NFCE)的数据传播算法。第一步,D2NFCE需要根据任意两辆车之间的移动方向和速度估计主动连接时间间隔。其次,通过建立小波神经网络流量模型,拟合VDTNs的吞吐量函数;然后,对有效连接时间间隔内的吞吐量函数进行积分,得到节点的转发能力估计。然后,通过节点转发能力估计,设计了VDTNs的高效路由算法。最后,在机会网络仿真器(ONE)上对D2NFCE进行了仿真。实验结果表明,与现有技术相比,D2NFCE可以大大提高数据传播效率,降低传输延迟、时延抖动和数据包丢包率。

Monic Testing of Web Services Based on Algebraic Specifications 基于代数规范的Web服务一元测试
Pub Date : 2016-03-01 DOI: 10.1109/SOSE.2016.45

Web services are designed to be discovered and composed dynamically, which implies that testing must also be done dynamically. This involves both the generation of test cases and the checking of test results. This paper presents algorithms for both of these using the technique of algebraic specification. It focuses in particular on the problem that web services, when they are third-party, have poor controllability and observability, and introduces a solution known as monic floating checkable test cases. A prototype tool has implemented the proposed testing technique and it is applied to a case study with a real industry application GoGrid, demonstrating that the technique is both applicable and feasible.

Web services play an important role in today's business economy, allowing the development of distributed applications and systems over the Internet. The challenge of finding the 'right' web service, which meets a consumer's functional and non-foundational requirements, has increased with the growing numbers of web services. Web service discovery initiates the process of finding, locating and retrieving existing web services based on consumer requirements. Different web service discovery approaches have been proposed by researchers, based on different techniques and strategies. To understand the different components of discovery systems, on the poster, we discuss the process of web service discovery, the challenges of web service discovery and our proposed taxonomy of web service discovery systems based on five perspectives.
Web服务在当今的商业经济中扮演着重要的角色,它允许在Internet上开发分布式应用程序和系统。随着web服务数量的增加,寻找“正确的”web服务(满足消费者的功能性和非基础需求)的挑战也在增加。Web服务发现启动基于消费者需求的查找、定位和检索现有Web服务的过程。基于不同的技术和策略,研究人员提出了不同的web服务发现方法。为了理解发现系统的不同组成部分,我们在海报上讨论了web服务发现的过程、web服务发现的挑战以及基于五个视角提出的web服务发现系统分类。
