    Get PDF
    We argue that for a true realization of innovative programming opportunities for smart spaces, the developers should be equipped with informative tools that assist them in building domain-related applications. Such tools should utilize the services offered by the space's smart things and consider the different relationships that may tie these services opportunistically to build applications. In this paper, we utilize our Inter-thing relationships programming framework to present a distributed programming ecosystem. The framework broadens the restricted set of thing-level relationships of the evolving social IoT paradigm with a set of service-level relationships. Such relationships provide guidance into how services belonging to different things can be combined to build meaningful applications. We also present a uniform way of describing the thing services and the service-level relationships along with new capabilities for the things to dynamically generate their own services, formulate the corresponding programmable interfaces (APIs) and create an ad-hoc network of socially related smart things at runtime. We then present the semantic rules that guide the establishment of IoT applications and finally demonstrate the features of the framework through a proof-of-concept application

    A conceptual architecture for adaptation in remote desktop systems driven by the user perception of multimedia

    Full text link
    Current thin-client remote desktop systems were designed for data-oriented applications over low-quality LAN links and they do not provide satisfactory end-user performance in enterprise environment for more and more popular graphical and multimedia applications. To improve perception of those applications in thin-client environment we propose architecture of a server-side Quality of Service (QoS) management component responsible for mapping application QoS requirements into network QoS. We analyze how service differentiation and traffic management techniques combined with user perception monitoring can be used in order to adjust network level resource allocation when performance of multimedia applications in remote desktop environment is not meeting user requirements. Our objective is to provide QoS-aware remote desktop systems which will be able to manage available resources in intelligent manner and meet end-user performance expectations. ยฉ 2005 IEEE

    There is not discussion about the need of energy conservation, it is well known that energy resources are limited moreover the global energy demands will double by the end of 2030, which certainly will bring implications on the environment and hence to all of us. Non-Intrusive load monitoring (NILM) is the process of recognize electrical devices and its energy consumption based on whole home electric signals, where this aggregated load data is acquired from a single point of measurement outside the household. The aim of this approach is to get optimal energy consumption and avoid energy wastage. Intrusive load monitoring (ILM) is the process of identify and locate single devices through the use of sensing systems to support control, monitor and intervention of such devices. The aim of this approach is to offer a base for the development of important applications for remote and automatic intervention of energy consumption inside buildings and homes as well.  Appliance discerns can be tackled using approaches from data mining and machine learning, finding out the techniques that fit the best this requirements, is a key factor for achieving feasible and suitable appliance load monitoring solutions. This paper presents common and interesting methods used. Privacy concerns have been one of the bigger obstacles for implementing a widespread adoption of these solutions. The implementation of security over these approaches along with fine-grained energy monitoring would lead to a better public agreement of these solutions and hence a faster adoption of such approaches. This paper reveals a lack of security over these approaches with a real scenario. &nbsp

    Get PDF
    With the prevalence of sensor-rich smartphones, MCS has become an emerging paradigm to perform urban sensing tasks in recent years. In MCS systems, it is important to minimize the energy consumption on devices of mobile users, as high energy consumption severely reduces their participation willingness. In this article, we provide a comprehensive review of energy saving techniques in MCS and identify future research opportunities. Specifically, we analyze the main causes of energy consumption in MCS and present a general energy saving framework named ESCrowd that we use to describe the different detailed MCS energy saving techniques. We further present how the various energy saving techniques are utilized and adopted within MCS applications and point out their existing limitations, which inform and guide future research directions

    Recently the demands of the Internet services for the mobile environment are rapidly increasing with the growth of the Internet. Nevertheless, the technologies for the services are just in the beginning. A few simple services are only provided as compared with the diverse services on the wire-networked Internet. The mobile devices are so handicapped in many ways that the technologies should be different with those for the desktop systems. A Small display, no keyboard, and the low bandwidth of the mobile network should be considered to develop the Internet services for the mobile environment. The Internet technologies such as mobile IP, WAP, WML, VoiceXML, and the mobile browsers are appeared for the mobile Internet services. In this paper, the mobile Internet technologies are adapted to the audio teleconference service. Because the service is one of the most important Internet services, and also the mobile devices usually have the telephone functionalities, the service is going to be the killer application of the mobile Internet services. The technologies including WML, VoiceXML, and H.323 are appropriately tailored and the architecture of the service is proposed. The architectural model is implemented in a simulated mobile environment. The mobile audio teleconference service with the WWW and ftp services is proven to be very feasible with the architecture and tailored technologies proposed in this paper.๋ชฉ์ฐจ Abstract = ii ์ œ1์žฅ ์„œ๋ก  = 1 ์ œ2์žฅ ๊ธฐ๋ฐ˜๊ธฐ์ˆ  ์—ฐ๊ตฌ๊ณ ์ฐฐ = 4 2.1 VoiceXML(Voice eXtensible Markup Language) = 4 2.2 WML(Wireless Markup Language) = 8 2.3 H.323 (ํšŒ์˜ ์‹œ์Šคํ…œ์„ ์œ„ํ•œ ํ‘œ์ค€) = 10 ์ œ3์žฅ ์ด๋™ ๋‹จ๋ง๊ธฐ๋ฅผ ์œ„ํ•œ ํšŒ์˜ ์‹œ์Šคํ…œ = 16 3.1 ํšŒ์˜ ์‹œ์Šคํ…œ ๊ตฌ์กฐ๋ฅผ ์œ„ํ•œ ๊ฐ€์ • = 16 3.2 ๋‹ค์ž๊ฐ„ ํšŒ์˜ ์„œ๋น„์Šค๋ฅผ ์œ„ํ•œ ์‹œ๋‚˜๋ฆฌ์˜ค = 16 3.3 ๊ธฐ๋ฐ˜๊ธฐ์ˆ ์˜ ๋ฌธ์ œ์ ๊ณผ ํ•ด๊ฒฐ๋ฐฉ์•ˆ = 18 3.4 ์ œ์•ˆ ๋ชจ๋ธ์˜ ๊ธฐ๋ณธ ๊ตฌ์กฐ = 21 3.4.1 ๋‹ค์ž๊ฐ„ ํšŒ์˜ ์‹œ์Šคํ…œ์„ ์œ„ํ•œ ๊ธฐ๋ณธ ๊ตฌ์กฐ = 21 3.4.2 ๋‹จ์ˆœ ์Œ์„ฑํšŒ์˜ ์ ‘์† = 22 3.4.3 ์Œ์„ฑํšŒ์˜ ๋„์ค‘ ๋ฐ์ดํ„ฐ ์„œ๋น„์Šค = 23 3.5 ์Œ์„ฑ ํšŒ์˜ ์‹œ์Šคํ…œ์„ ์œ„ํ•œ ๋™์ž‘ = 24 ์ œ4์žฅ ์‹คํ—˜ = 28 4.1 ์‹คํ—˜ํ™˜๊ฒฝ = 28 4.2 VoiceXML๊ณผ WML์„ ํ†ตํ•œ ๋ฉ”๋‰ด ์ถœ๋ ฅ = 29 4.3 ์Œ์„ฑ ํšŒ์˜ ์„œ๋น„๏ผŸ๋ณด๏ผŸ ์œ„ํ•œ ๋™์ž‘ = 33 ์ œ5์žฅ ๊ฒฐ๋ก  = 34 ์ฐธ๊ณ ๋ฌธํ—Œ = 3

    Persuasive Health:Back to the Future

    Get PDF
    With individual behaviour and lifestyle determining 30-50% of peopleโ€™s health, research and supportive technology for affecting behaviour alteration remain urgently needed. Most existing persuasive systems are designed to persuade a user to change a finite set of behaviours to achieve a specific goal. However, if the userโ€™s situation or goal changes, such systems cannot adapt to the changes. A much more robust type of persuasive systems is needed today to enable adequate health navigation and to empower people to face and change their own realities in terms of a large variety of health behaviours and lifestyles. In this paper, we provide a perspective on the impressive body of work contributed over the past 15 years, to better look into the future of persuasive health and to the opportunities a broader theoretical framework and practical methodologies may bring about. We present a taxonomy that attempts to explain the contributions in this field including health behaviour theory, cybernetic action behaviour models, social cognitive theory, and control theory. We identify potentially promising approaches to advance persuasive healthโ€™s efficacy in empowering individuals to improve their own health outcomes

    IoTility:Architectural Requirements for Enabling Health IoT Ecosystems

    Get PDF
    The increasing ubiquity of the Internet of Things (IoT) has the potential to drastically alter the way healthcare systems are utilized at home or in a care environment. Smart things offer new ways to assist in general patient wellness, such as promoting an active and healthy lifestyle and simplifying treatment management. We believe smart health things bring new requirements not typically addressed in traditional IoT systems, and that an architecture targeting these devices must address such requirements to fully utilize their potential and safe usage. We believe such an architecture will help improve adoption and efficacy, closing gaps between the variety of emerging health IoT systems. In this paper, we present a number of requirements we consider integral to the continued expansion of the digital health IoT ecosystem (Health IoT). We consider the current landscape of IoT in relation to these requirements and present solutions that address two pressing requirements: 1) democratizing mobile health apps (giving users control and ownership over their app and data), and 2) making mobile apps act and behave like any other thing in an IoT. We present an implementation and evaluation of these Health IoT requirements to show how health-specific solutions can drive and influence the design of more generalized IoT architectures
