The growing demand for ubiquitous computing lead manufactures to develop multi-band devices supporting different network access technologies, such as GSM, Wi-fi, and UMTS. Although these devices support different access technologies, they lack of native vertical handover support, breaking any ongoing connections whenever users switch between access technologies. In this paper we present a next-generation...
Airport terminals will increasingly require ubiquitous communications systems with high levels of computational power to provide the necessary intelligent automation to provide high quality services to passengers, stringent levels of safety and security that is as unobtrusive as possible, efficient processing of commercial goods and luggage, high quality information systems, airport transportation...
Pervasive Environments offer new opportunities for users to dynamically access resources and services based on information characterizing their situation (context), generally assuming that this information is correct and trustworthy. In this scenario, the Quality of Context information (QoC) plays an important role for improving context-based adaptation processes and for ensuring the correct behavior...
Pervasive systems are increasingly being designed using a service-oriented approach where services are distributed across wireless devices of varying capabilities. Service orchestration is a simple and popular method to coordinate web-based services but introduces a single point of failure and lacks the flexibility to cope with the greater variability of pervasive environments. Choreography in contrast...
In pervasive environments, services are fastly developing and are being deployed everywhere. In this article, we introduce a Servicebook, a new social network of services, where services create and join group of service profile providing to users better access to all the services in their vicinity. We propose a novel technique to realize this Servicebook, the user-excentric service composition. This...
The advances in distributed sensing and wireless communication enable pervasive home applications which are quit information-rich. Hereby the integrated access and management of heterogeneous information becomes an increasingly important research topic. Moreover recent popularity and advances in visual aids (Google maps, 3D computer graphics, PS games, etc.) call for the more attractively intuitive...
Some types of contextual information are more important than others for inferring a situation of the patient in home-based care. The weight of this information may be changed due to the variations of the sensed values over time. Some researches applied a static weighting based fusion process to their systems to model these variations. However, this fusion process sometimes reduces the reliability...
The following topics are dealt with: performance modelling; routing mechanism; distributed systems; parallel systems; service oriented architecture; communication technology; protocols; autonomic network systems; Internet computing; ad hoc networks; wireless sensor networks; privacy management; mobile networks; multimedia systems; pervasive computing; ubiquitous computing; security intrusion detection;...
To adapt communication in order to maintain the connectivity and the quality of communications in group-wide collaborative activities becomes challenging when considering mobile entities in a wireless environment, requiring responsiveness and availability of the communication system, and designing self-adaptable communication architecture remains a complex task. To simplify this task, semantic presents...
