In residential environments, a home gateway platform can offer services that are configurable by a user depending on current needs or preferences. Gateway devices are very often managed by a service provider or an access provider to enhance performance or guarantee QoS. Assuming a multi-provider and/or multi-user scenario, a secure framework has to maintain security and privacy between different gateway...
Large and complex systems design is still being a challenge even bigger when developing embedded, distributed or real-time systems. OSGi is a platform created to reduce some of the software design problems, increasing reusability, modularity, etc. While, MDA is also designed to simplify software process development using different modelling layers. This paper describes how OSGi services can be designed...
This article is based on the idea of lowering the risk of taking erroneous decisions under stress or panic. There are many environments in which wrong decisions may cause severe problems; good examples are airplane control or nuclear power plant monitoring. The crucial issue is to detect the point of transition from a well-thought decision into a decision taken under stress. Sensors support monitoring...
This paper describes the Network Service Access (NSA) layer that enables transparent interoperability between the applications running over a car-gateway's OSGi middleware and the devices in a UPnP network. It also raises shortly the problems in bridging both standards and applying them to on-board embedded systems like a car-gateway or vehicular networks. Best efforts are focused on providing solutions...
Several European research projects in the vehicular area address the enhancement of vehicular safety. In the frame of the Caring Cars project, an on-board car-gateway embedded architecture for safety and wellness applications has been designed. This paper puts forward the essentials of this modular, dynamic and robust architecture and defines in detail the advanced emergency call (eCall+), one of...
This paper shows current problems in IPv6 technology implementations and their solutions, using a Universal-Plug-and-Play (UPnP) case study. The motivation for this work was a real difficulty found using UPnP over IPv4 to access devices from one home from another home (using private IPv4 addresses for UPnP devices), solved elegantly in theory using IPv6. For this purpose, a local environment was set...
This paper discusses an innovative extension of a platform that integrates external intelligent environments into state-of-the-art vehicles. The platform is dedicated to automotive environments for sensor networks focusing on distribution along a personal area vehicle network. Since the platform infrastructure is currently limited and forms a non scalable process unit, an embedded OSGi-based UPnP...
The residential gateway (RGW) is a key infrastructure component in home networks. Nowadays, the Open Service Gateway Initiative (OSGi) seems to be the only platform alternative supporting hot-plug of services and an easy way to deploy new ones which are capable to integrate heterogeneous devices into a common platform. But this platform can be managed by only one manager in a secure way, and this...
There is continuously increasing number of devices available which support multimedia management and enable capabilities of interconnection beyond the borders of a Residential Gateway. This paper focuses on devices providing multimedia content (Media Server) and devices reproducing the contents (Media Renders). The objective is to discover, manage and use remote devices like local resources. The setup...
Learning management systems (LMSs) typically provide a wide set of functionalities to support students' learning such as file storage, forums, calendar, news, bulk mail, submission management system, groups surveys, organization, assessments, FAQs (Frequently Asked Questions) or scheduling. This paper evaluates and compares the importance of different LMS functionalities and analyses the effect on...
A residential gateway can offer services that are configurable by a user depending on current needs or preferences. A set of these preferences can be grouped to form a user profile. One user may own several profiles depending on the environment (home or office) or time (working time or weekend). This article proposes smart cards for storing profiles and maintaining profiles in a secure and portable...
This work proposes an integration of smart cards into a residential gateway. The aim is to extend services offered by the gateway with the functionalities provided by the smart card. Thanks to this integration, functionalities like cryptographic services, secure payments for pay-per-view or environment's customization can be made available. The core of this work has been carried out in order to achieve...
