Applications based on micro or web services have had significant growth due to the exponential increase in the use of mobile devices. However, using such kind of loosely coupled interfaces provides almost no guarantees to the developer in terms of evolution. Changes to service interfaces can be introduced at any moment, which may cause the system to fail due to mismatches between communicating parts...
This article proposes a path for doing Data Science using browsers as computing and data nodes. This novel idea is motivated by the cross-fertilized fields of desktop grid computing, data management in grids and clouds, Web technologies such as NoSQL tools, models of interactions and programming models in grids, cloud and Web technologies. We propose a methodology for the modeling, analyzing, implementation...
Traffic localisation is an important aspect of traffic management on the Internet. The caching of content and its distribution from localised servers is one mechanism that enables traffic localisation and reduces transit costs for network providers while enhancing service performance. However, personalized, dynamic user content is often un-cacheable due to its nature. As we move towards a world of...
The success of context-aware systems depends on intuitive user interface designs which facilitate communication between multiple devices. This paper presents Throw It, a natural user interface for sharing objects between mobile devices using gaze and hand gestures. For enabling gesture control, Throw It includes an off-the-shelf monochrome camera with infrared lights and a hand-held 6 degree of freedom...
Many network operators have recently started to deploy their own Content Delivery Networks (CDNs) within their administrative domain. Having a CDN deployed within an operator's network has the advantage of potentially placing caches very close to the end user, thereby increasing Quality of Service for the user, while at the same time saving delivery costs for the operator. However, if each network...
The global mobile application market is booming and business giants, viz. Google and Apple, have acknowledged the huge expansion in their respective application market. There is a demand though for a system that can elevate the momentum of context-aware mobile applications, where application behavior can be customized according to various context information. This paper proposes AppaaS, a context-aware...
Context-Aware Communication (CAC) services enable end-devices or service platforms to adapt their comportment to sensed context information, either instantly or in a deferred way. There is today no available framework for supporting the development of CAC applications in a generic way. After surveying previous works, we propose here a new approach for classifying context-aware communication systems...
Most existing location-based services rely on ubiquitous connectivity to deliver location-based contents to the users. However, connectivity is not available anywhere at anytime even in urban centres. Underground, indoors, remote areas, and foreign countries are examples situations where users commonly do not have guaranteed connectivity but could profit from location-based contents. In this work,...
We present an ontology-based reasoning approach for saving energy in a smart home setting where a mobile phone can serve as a generic sensor which can collect the inhabitant's contextual data. The paper details an ontology that describes the smart home domain and a prototype to test the system. Finally, we conclude with lessons learned from our work in developing an energy-aware smart home prototype...
We propose a system for the acquisition, maintenance, and communication of Real-World Achievements. The concept is based on online entertainment systems like Microsoft's XBox Live or virtual worlds like World of Warcraft. The system design is centered around a global database of achievement definitions and individual progress. Focus is put on flexibility to track achievement-related actions and instantaneous...
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...
Recently, as smartphone is becoming more and more popular, concern about security threats against Mobile Communication Device (MCD) is getting higher. The MCD can not only become the target of the cyber attacks, but also be used as the tool of the cyber attacks. This paper proposes a context-based remote security control scheme for MCD. The proposed scheme consists of two systems: Context-based Mobile...
At last year's ICUFN we presented an architecture for managing ubiquitous computing networks and applications [1]. This year we want to show how we can implement this architecture to realise and deploy a small yet powerful management system. The use case for demonstrating our implementation is one of the most commonly used ubiquitous service - instant messaging. The described management system is...
In this paper, we present a novel method for image annotation and retrieval on mobile device by using contextual information. Image annotation is an effective way for content based image retrieval. However, manual annotation is an expensive and time consuming work, especially for mobile device. Here, we propose a semi-automatic way to give image annotation on mobile device. There are rich contexts...
In this paper, we propose a context-aware Input Method Editor (IME) as a ubiquitous service for improving the input of text on mobile devices. In our proposed IME, it estimates the context of users according to position information from GPS (Global Positioning System) sensor or a presence information from the Internet. Simultaneously, it generates a personal context-aware dictionary dynamically from...
This paper presents an autonomic system for composing ubiquitous applications at run-time. The applications are composed according to the user preferences collected via a physical user interface. This interface allows users to specify preferences by simple actions of touching with their mobile terminals icons in the environment, instead of explicitly selecting resources and dealing with their properties...
Content adaptation is an attractive and effective solution to resolve the mismatch of resources and properties between the delivery context and the multimedia content in heterogeneous environments. The problem with multimedia content adaptation is that there is no a single complete software solution that can satisfy all types of required adaptation needs. In order to solve this problem adaptation...
