This paper aims to contribute to situation, activity, and goal awareness in cyber-physical human–machine systems (HMS) by presenting a new information model and specifications for a decision-making component that can be integrated in current system architectures. The objective of this work is to improve the efficacy, acceptance, adaptability, and overall performance of HMS and human–system interaction...
This paper introduces a methodology to design a Context-aware Adaptive System based on a layered software architecture. The model of the context awareness multi-modal traffic management takes into account the context parameters in order to adapt dynamically the decisions (choice of the best transportation route). The efficiency of the proposed technique is validated through a case study including...
The size of data chunk diverges from 101 to 1010 bits. Generally, if a network carries in a way both of big size data and small size data, the performance is extremely degraded by the big size data. Then, we propose to select a wireless cell among of multiple cells by referring context information such as data size and user's situation such as moving velocity. Especially, we show the improvement on...
Context Aware Systems (CAS) support mobility of users and make context reasoning efficiently to provide relevant and real-time information. CAS should be particularly adaptive and aware by managing and responding properly to occurring events. Due mainly to the presence of numerous sensors and access to several communication networks, Context-awareness has been successfully included in the mobile device...
The current service discovery mechanisms are syntactic methods that often offer poor quality results. By researching this area we are able to identify issues that limit the quality of the result with these traditional service mechanisms. To overcome this issue we use ontologies to enable semantic matchmaking. By reasoning on concepts and relations, our approach can derive matches that syntactically...
We propose a novel software platform based on the notion of context-awareness which allows rapid and easy development of context aware applications. One of the fundamental goals of the proposed platform is extensibility, allowing the platform to react to new requirements without making fundamental and substantial changes. The Context Aware Application Development Platform- PCAD- has inspired from...
Context-awareness plays an important role to offer an intelligence in terms of provision of user-centric features in Internet of Things (IoT). Web of Objects (WoO) has been introduced to support a framework to simplify application deployment, maintenance and operation of IoT service infrastructure by classifying and integrating objects on the World Wide Web. The semantic ontology is applied on a WoO...
In the last years a new computing paradigm called Internet of Things (IoT) has been gaining more attention. This paradigm has become popular by embedding mobile network and processing capability into a wide range of physical computing devices used in everyday life of many people. An important part that composes the IoT is the middleware, which is a system that abstracts the management of physical...
Mobile Cloud Computing has been worldwide accepted as a concept that can significantly improve the user experience when accessing mobile services. Mobile applications have become more popular all across the world. By removing the limitations of mobile devices with respect to storage and computing capabilities and providing new integrated levels of security by centralized maintenance of security-critical...
Disasters and emergencies are featured by their unexpected consequences on the human being life. Crisis Management Systems (CMS) handling them require effective collaboration between their services, and need dynamic adaptation at runtime when an execution context change occurs. To manage disasters, several approaches are proposed in the literature where few of them have advocated context-awareness...
Today, data from different sources and different phases of the product life cycle are usually analyzed in isolation and with considerable time delay. Real-time integrated analytics is especially beneficial in a production context. We present an architecture for data- and analytics-driven exception escalation in manufacturing and show the advantages of integrating unstructured data.
The exponential increase in the number and types of mobile devices, along with their ever-growing sets of capabilities, have enabled the development of new architectures that aim to harness such heterogeneity. Transient Clouds (TCs) are examples of mobile clouds which are created on-the-fly by the devices present in an environment to share their physical resources (e.g., CPU, memory, network) and...
Cultural Heritage represents in Italy a resource of inestimable value. This value gains more and more importance when embedded into the digital ecosystem of a Smart City, where several aspects must be considered: logistics, economy, tourism, entertainment and so on. This work presents a project, developed within DATABENC (a High Technology District for Cultural Heritage Management recently funded...
In response to the challenges for application development, deployment, running and maintenance in an open, dynamic, difficult to control for Internet platform, the concept of Internetware came into being. It is a new software architecture, which is flexible to evolution, continuously reactive and adaptive to multiple targets. Software entities form a software web, which is similar to current information...
Context-awareness is becoming an important foundation of adaptive mobile systems, however, techniques for discovering contextually relevant Web content and Smart Devices (i.e., Smart Resources) remain consigned to small-scale deployments. To address this limitation, this paper introduces Ambient Ocean, a Web search engine for context-aware Smart Resource discovery. Ocean provides scalable mechanisms...
The applications in Ubiquitous Computing (UbiComp) environments must be aware of their contexts of interest and adapt to changes in them. Thus, a major research challenge in the area of UbiComp is related to context awareness. Considering the high distribution, heterogeneity, dynamism, and mobility of ubiquitous environments, this paper presents an architecture for context awareness, named UbiC (Ubiquitous...
Nowadays, as mobile smart terminals are becoming increasing widespread and multitudinous sensors are included, the applications with various new functions that run on mobile terminals are largely expanded. This paper proposes a Cross-Platform and Context-Awareness (CPCA) middleware intended for application developers, by which they can develop context-aware applications by providing the context reasoning...
With the rapid development of mobile cloud computing, the identity authentication has become more and more important. but most of the authentication methods were authenticating device rather than users. Context aware information, such as, operational context, personal context, spatial context, and environmental context, can provide users with their really needed services without any explicit requests...
Context aware computing as well as wearable and ubiquitous computing often attain with pattern recognition on incoming sensor data. Recognizing more (useful) contexts requires more information about the context, and thus more sensors and better recognition algorithms. In order to enable logic inference on incoming data, the proposed work assumes that incoming data are represented by means of semantic...
