Abstract. Accessing geospatial data via the internet is a common way for integration. This web mapping approach often relies on services like map tile service (WMTS) accessing maps or feature (WFS) vector data. An alternative way, which combines aspects higher performance through tiling and usage of tiled short paper describes an creation using standard PostgreSQL, with spatial extension PostGI...

The increasing complexity, heterogeneity and dynamism of emerging pervasive Grid environments and applications has necessitated the development of autonomic self-managing solutions, which are based on strategies used by biological systems to deal with similar challenges of complexity, heterogeneity, and uncertainty. This paper introduces Project AutoMate and describes its key components. The ov...

Remote Instrumentation Services go far beyond offering networked access to remote instrument resources. They are establishing as a way of fully integrating instruments (including laboratory equipment, large-scale experimental facilities, and sensor networks) in a Service Oriented Architecture, where users can view and operate them in the same fashion with computing and storage resources. The de...

The areas of collaborative applications and infrastructures are closely related—novel collaborative applications cannot become commonplace unless an effective infrastructure is developed to support their implementation. The recent focus on collaborative applications that support WYSIWIS (What You See Is What I See) collaboration is a direct consequence of the fact that such collaboration is aut...

The contribution of this thesis is the study, design and implementation of a resilient and secure communication infrastructure for decentralized peer-to-peer networks. On today’s Internet, free and unrestricted communication between users is often restricted due to limited connectivity between participants, attempts to degrade service for certain traffic classes and other filtering and manipula...

This paper describes a monitoring framework called GEMINI (Generic Monitoring Infrastructure), developed as part of the EU-IST Project K-WfGrid, intended to collect, store and deliver diverse monitoring information about a variety of resources including Grid infrastructure and applications. GEMINI aims at providing a generic sensor that can be used to capture various types of monitoring data an...
