This paper presents a framework for providing survivability to group communications where part of the underlying trafsic layer infrastructure is connectionoriented. The framework is multi-layered to express the virtual overlays inherent to networked systems, describes survivability issues unique to group communications, and outlines tradeoffs between restoration techniques that can be extended ...

Current and emerging manufacturing and logistics systems are posing new challenges and opportunities for the automation and control community. This milestone report describes the main problems, such as management of complexity, scalability, increasing costs, coordination, market-based resource allocation, and more. Recent accomplishments and trends are discussed: Control and automation techniqu...

In this paper we present a distributed and modular system to convey small and fragile objects. This is done by attaching similar modular blocks together to form a larger conveyance surface. Similar to other networked control systems, each block is composed of several sensors, actuators and communication infrastructure. Control of a levitating object should be done distributed and real-time. We ...

The advancement of the self-forming, multi-hop Mobile Ad-hoc Wireless Networks (MAWN) creates the need for new analysis methods which enable the accurate determination of the reliability and availability of these networked systems. Contrary to hardwired networks, MAWN is a scalable network without infrastructure. Along this line, the MAWN’s configuration forms dynamically and probabilistically ...

Distributed Virtual Environment systems simulate the behaviour and activities of a great number of users interacting in a virtual world over a wide area network. The sizes of the virtual worlds and the tremendous number of users that DVEs are called to support require additional bandwidth and computational resources. For handling these growing requirements a lot of work has been done both to th...

Different forms of web-based collaborations are continuously configured and growing. Such emerging collaborative networks (CNs) are exemplified by Virtual Organizations, Virtual Communities, and Virtual Laboratories. Design and development of these environments constitute long, incremental, and complex processes. One challenge in this process is the proper definition of required syntax for enti...

Forschungsplattform Alexandria https://www.alexandria.unisg.ch | 06.05.2013 Both, the logistics and insurance companies rely on software intensive systems and IT-infrastructure to run their core business operational. In recent years ITimprovements have resulted e.g. in better tracking and tracing capabilities for the whole logistics industry. Designing an interface in this case between the logi...

More and more companies are realising that business is best carried out in project-based virtual alliances and are intensively networking and collaborating with partner companies. This requires convergent, adaptive, and interoperable IT environments ready to support flexible, loosely coupled networked enterprises, anywhere, anytime regardless of heterogeneous systems and applications in use. Th...

We envision the blossoming of sensing applications in an urban context, enabled by increasingly affordable and portable sensing hardware, and ubiquitous wireless access to communication infrastructure. In this paper, we describe the Partisans architecture, featuring infrastructure-supported selective data sharing and verification services. This effort represents an evolution of activity on embe...

“Smart” sensors with embedded microprocessors and wireless communication links have the potential to fundamentally change the way civil infrastructure systems are monitored, controlled, and maintained. Indeed, a 2002 National Research Council Report [1] noted that the use of networked systems of embedded computers and sensors throughout society could well dwarf all previous milestones in the in...
