Wireless sensor networks (WSNs) belong to emerging technologies where network devices can interact with the surrounding environment by sensing physical parameters. Recently, with the dissemination of mobile devices to Internet connectivity, users can interact with sensor networks and collect environmental data, anytime, anywhere using user-friendly mobile applications. Following the Internet of Things...
Data synchronous dynamic update is a main issue for the Service-Oriented Architecture (SOA) application system that is widely employed in distributed systems such as e-commerce and e-government. Technologies based redundancy is usually employed for building reliable service composition on top of unreliable Web-based application. Through the Caller-ID and the intelligence mobile phone use widely, the...
In the conventional asset management systems, users cannot customize services sets flexibly because of certain fixed mode in the systems. Another problem is that, the systems which integrate RFID technology to monitor the assets have to be redeployed when the RFID equipments are replaced. In this paper, we propose an open mobile asset management system based on OSGi to solve these problems. On the...
We observe two of the recent trends in information technology. Cloud Computing (CC) is widely accepted as an effective reuse paradigm. Mobile Computing with Mobile Internet Device (MID) such as iPhones and Android devices becomes a convenient alternative to personal computers by integrating mobility, communication, software functionality, and entertainment. Due to the resource limitations of MIDs,...
Mobile devices are now equipped with multiple sensors and networking capabilities. They can gather information about their surrounding environment and interact both with nearby nodes, using a dynamic and self-configurable ad-hoc network, and with distant nodes via the Internet. While the concept of mobile agent is appropriate to explore the ad-hoc network and autonomously discover service providers,...
As wireless networks and mobile devices are becoming ubiquitous, mobile users are increasingly requiring access to application services that can adapt to their context as they move to new locations, for example, in their corporate or partners' networks. The quality-of-context information (QoC) used by these application services is a determinant factor in the adaptation process. As application services...
The platforms and gateways that compose the Airborne Network (AN) exhibit a high degree of heterogeneity, with a variety of IP and non-IP data links hosted on various terminals produced by multiple manufacturers. The lack of an accepted, mature network management architecture for the AN contributes to the risk that there will be a proliferation of separate, stovepiped tools deployed to monitor and...
In this paper, we propose an approach to face emergencies and risky situations through real-time wearable services in industrial environments. We outline the social and technological features of a wearable-based service system, which aims to improve safety in workplaces. To achieve this goal, we propose a system composed of real-time wearable services constituting a platform able to prevent the occurrence...
In this paper, we describe an extensible toolkit for creating, testing and executing context-aware mobile applications. Our aim is to facilitate research in wearable & ubiquitous computing by providing an experimental framework into which novel sensors, networking mechanisms, web services and algorithms can easily be added and explored. The paper describes the toolkit, an SDK used to create plug-ins,...
Traffic security is one of the most important problems to be improved for our daily environment, especially in Japan. Surveillance systems are effectively used to observe intrusion into dangerous and security area. They are well evaluated to monitor whether people enter such an area or not. A remote surveillance system has been developed, which supports users of mobile phones to facilitate network...
While new competitors are threatening the traditional business models of Telecommunications operators by providing their services directly to the customer, user-centric service creation paradigm brings new opportunities for operators to deliver diverse, attractive, and profitable services directly to the end-user. This paper discusses the service creation model, architecture and implementation in...
This paper presents a system for a location-based discovery of points of interest, based on the current geographic position of mobile users. The proposed approach exploits a mixture of Web 2.0 technologies (for the localization of point of interests), positioning techniques and cross-layer networking schemes for a seamless navigation, while moving through different and heterogeneous wireless networks.
The concept of Mobile Web Services (Mob-WS) is catching pace within research communities due to rapid classification of mobile devices enabling pervasive environments. Beside consumer oriented use cases, another aspect of utilizing the potential of Mob-WS is to use them as computation resources within a wireless network. Such Mob-WS are called ldquoIn-network Mob-WSrdquo. In this paper we propose...
The concept of mobile Web services (Mob-WS) is catching pace within research communities due to rapid classification of mobile devices enabling pervasive environments. A Web service based middleware for mobile applications is a promising platform to accelerate the application development for mobile systems. This paper introduces a middleware for time independent Mob-WS that avoids the overheads of...
The most critical part of a construction project is normally the construction elements that form the structure of the building. Concrete construction elements are often used as support structures and on the facade of the building, but they are vulnerable to manufacturing defects as well as being damaged on-site. Such defects can create a lot of additional costs to all parties involved in the project...
With the increasing storage capacity, processing power and battery capabilities, mobile devices are now able to providing services instead of just being service consumers. This paper introduces a middleware for time independent mobile Web services (Mob-WS) that avoids the overheads of long durational synchronous communication. Details of communication architecture and interaction among the middleware...
Service-oriented architecture and Web services have become key enabling technologies to implement mobile software applications and services by integrating diverse services deployed in heterogeneous network environment independent of platforms and languages. The loosely-coupled nature and the independence of Web services, however, make it a challenging task to build applications with real-time constraints...
The increasing ubiquity of mobile embedded systems has been matched by the evolution of a variety of wireless network standards and technologies. The major constraints of wireless embedded systems are limitations of communication bandwidth, processing capabilities, and battery power. Remote wireless embedded systems often act as sensors, which provide data to a certain community. The exchange of data...
