As mobile and embedded devices become widespread, the management and configuration of the software in the devices is increasingly turning into a critical issue. OSGi is a business standard for the life cycle management of Java software components. It is based on a service oriented architecture where functional units are decoupled and components can be(More)
In this paper we take advantage of the concepts developed for centralized module management, such as dynamic loading and unloading of modules, and show how they can be used to support the development and operation of distributed applications. We do so through R-OSGi, a distributed middleware platform that extends the centralized, industry-standard OSGi(More)
Mobile phones are rapidly becoming the universal access point for computing, communication, and digital infrastructures. In this paper we explore the software architectures necessary to make the mobile phone a truly universal access point to any electronic infrastructure. We propose AlfredO, a lightweight middleware architecture that allows developers to(More)
One of the most important challenges that need to be solved before the " Internet of Things " becomes a reality is the lack of a scalable model to develop and deploy applications atop such a heterogeneous collection of ubiquitous devices. In practice, families of hardware devices or of software platforms have intrinsic characteristics that make it very(More)
Designing and testing distributed applications is still a difficult task that requires in-depth knowledge about networking issues. Eclipse is, among other things, a powerful and widely used IDE for the development of complex applications, in particular modular applications for the OSGi framework. Our R-OSGi middleware supports the seamless distribution of(More)
—Over the last three years, Android has established itself as the largest-selling operating system for smartphones. It boasts of a Linux-based robust kernel, a modular framework with multiple components in each application, and a security-conscious design where each application is isolated in its own virtual machine. However, all of these desirable(More)
Stream processing systems have evolved into established solutions as standalone engines but they still lack flexibility in terms of large-scale deployment , integration, extensibility, and interoperability. In the last years, a substantial ecosystem of new applications has emerged that can potentially benefit from stream processing but introduces different(More)
Writing applications for sensor networks often involves low-level programming. In this demo we show a generic sensor network platform (SwissQM/SwissGate) that provides a high level interface for programming sensor networks and also provides a multi-tier architecture for efficiently handling and optimising the operation of the network. The demo is based on a(More)
