Architectural Considerations for Personal Mobility in the Wireless Internet

Personal Mobility, and the need for it, is considered to be the main driving force behind the spreading of the Wireless Internet. Moreover wireless devices and applications are being developed based on a basic assumption that users need to get access to services regardless of their location and used equipment. Wireless Services, on the other hand, are very dynamic and have a vibrant configurati...

Modelling for Quality of Services in Distributed Geoprocessing

Geographic information (GI) services are increasingly the state of the art in geoprocessing, promising novel geospatial solutions, products and services. Dynamic chaining of GI services however, presents exciting quality of service (QoS) challenges. Consequently, sustainable use of GI services demands careful consideration of the diverse user requirements and the complexities of dynamic service...

Middleware Services for Dynamic Clustering of Application Servers (Ph.D. Thesis)

Nowadays, middleware are well-established technologies developed in order to make easier the implementation of distributed applications. Among these applications, this thesis focuses on the so-called enteprise applications. Usually, these applications exhibit stringent Quality of Service (QoS) requirements, which are to be met in order to enable them to carry out their tasks effectively. QoS ha...

A Mobile Agent Infrastructure for QoS Negotiation of Adaptive Distributed Applications

QoS-aware distributed applications such as certain Multimedia and Ubiquitous Computing applications can benefit greatly from the provision of QoS guarantees from the underlying system and middleware infrastructure. They must avoid execution glitches that affect the user’s perception of the application output. Most research in QoS support for distributed systems focuses on three aspects of QoS m...
