The potential of cloud-supported cyber–physical systems (CCPSs) has drawn a great deal of interest from academia and industry. CCPSs facilitate the seamless integration of devices in the physical world (e.g., sensors, cameras, microphones, speakers, and GPS devices) with cyberspace. This enables a range of emerging applications or systems such as patient or health monitoring, which require patient...
This paper discusses the design and development efforts made to collect data using an opportunistic crowdsensing mobile application. Relevant issues are underlined, and solutions proposed within the CHIST-ERA Macaco project for the specifics of collecting fine-grained content and context data are highlighted. Global statistics on the data gathered for over a year of collection show its quality: Macaco...
Approaches to making cloud operation more efficient, for example through scheduling and power management, largely assume that the workload offered from mobile, user-facing applications is a given and that the cloud must simply adapt to it. We flip this assumption 180 degrees and ask to what extent can we instead shape the user-centric workload into a form that would benefit such approaches. Using...
Crowdsensing has been used quite regularly in recent years to study smartphone usage. However context information associated with smartphone usage is mostly of the type geo-localisation, user mobility, temporal behavior etc. Furthermore most studies are not sufficiently user-centric i.e. don't consider the perception or cognitive aspects of the user. In this paper we collect data about social context...
The ability to locate wireless devices has many benefits as already mentioned by researchers. These applications include sport tracking, friend finders, security related jobs, surveillance etc. Performance of such security related services and surveillance would significantly improve if in addition to location, context of the user is also known. Thus in this paper, location based service is designed...
Currently, healthcare plays an increasingly important role in our life, meanwhile traditional healthcare is not convenient for the collection of medical information and the medical treatment when health problems come out timely. In order to achieve the purpose of medical care mobility, we combine multi-Agent technology with advanced mobile communication technology, and deploy Jade Agent to the Android...
Managing field staff is extremely difficult because you can't physically and constantly supervise them. In this paper, we introduce a Field Staff Management System based on android mobile, which uses GPS to locate and the third generation of mobile telecommunications technology to communicate with the server.
In the context of communication services, presence is defined as the willingness and ability of a user to communicate across a set of devices with other users, and thus an up-to-date user presence status represents an essential prerequisite for real-time communications. Smartphones are a rich source of presence-related contex information, however; this information is currently not applied by the prevailing...
This paper explores the notion of cross-source integration of cloud-based, context-aware information. The objective is to develop a new solution that incorporates remote, web based configuration of Android phones and advances the research area of context-aware information and web applications. It expands the notion of context-awareness harvesting from web applications, enabling automatic adaptation...
We describe Quality of Information (QoI) in terms of Type Theory in order to: clarify the meaning of QoI and desired capabilities of “quality aware” systems; to show how any quality metric can be expressed as a function of data and data provenance which negates the need for specific quality annotations; and to indicate how data processing may automatically be applied to deliver high quality information.
There is an increasing penetration of smart phones within enterprises. Most smart phone users now run both enterprise as well as personal applications simultaneously on their phones. However, most of the personal apps that are downloaded from public market places are hardly tested for enterprise grade security, and there have been instances of malware appearing in public markets that steal sensitive...
In this paper, we proposed the personalized service using user's profile in the smart phone environment. The wallet app in the smart phone gathers personal information, and generates the user profile, privacy is guaranteed. The server uses this profile and environment information to recommend personalized services. And using the feedback of user selection, the user's satisfaction rated could be improved.
The recent developments in pervasive services offer incredible opportunities to provide a host of efficiency enhancement to human users. In fact, although complex computational tasks still require server side resources, combination of rich content delivering devices, such as smart phones, together with wearable I/O devices and wireless broadband networking, can be used to seamlessly weave a mesh of...
Advanced context-aware telecom services require evaluating rules encompassing local or remote, raw or abstract context situations. The meteoric rise of smartphones raises the question of potential deployment of terminal-based context-aware services versus a network-centric one. In this paper we compare these two approaches through the analysis of typical context-aware services.
Several studies both in the field of psychology and in the field of physiology relate stress to the difficulty of transferring information from short term memory to medium term memory. This difficulty causes a reduction in personal efficiency and generates heavy frustration as things to do tend to come to mind with no relation to the user current environment, thus further increasing the stress level...
This paper presents a library navigation system named LiNS, using a combination of Web, sensor and smart phone technologies. In addition to the function of an ordinary book search system, LiNS provides a library user with the function of finding the route from the current location point in the library to the point where the object the user needs is located. Furthermore, it offers the “See Also” function...
With the recent popularization of smart phones, context sharing systems in mobile environment attract attention of people. Mobile context sharing systems can share more information than web-based social network services because they have various sensors. For sharing high-level contexts such as activity and emotion, a user had to manually annotate them in previous works. This paper proposes a mobile...
Modern Smartphones are the fastest growing computing platforms capable of consuming Web services. However, due to their form factor these mobile computing devices face many challenges and constrains when engaging service providers. How to overcome these challenges and how to link smartphones to the service cloud is one of the key issues that will have a major impact on the further growth of the software-as-a-service...
Mobile learning is transforming the way of tradition education. But most of e-learning system and contents are not suitable for mobile device. In order to provide suitable mobile learning services, the approach for self-adaptation is proposed in this paper. Firstly, the formal definitions of context and its influence on learning service, including NCxt, side S, weighing Q and adaptation coefficient...
With appearance of mobile devices such as cell phones, PDAs and smart phones, context-aware applications are becoming increasingly popular. Therefore, developers are always seeking for new and powerful developing tools for context-aware programming. Developers prefer to use fast and convenient development tools that can support all required possibilities for implementing a complete and user-friendly...
