The future multi-layer optical networks based on wavelength division multiplexing technology will lead to the creation of new value-added optical services, which is bound to transform the traditional passive transport network into an active and intelligent transport layer. The successful deployment of these complex networking services and the possibility of subjecting them to a dynamic control,...

This thesis presents a framework that offers tools for the design and the implementation of Ubiquitous computing systems supporting user motions, activities and situations. With the rapid development of context-aware mobile computing and sensor-based interaction, many new challenges come up, three of which are particularly addressed in this thesis. The first is the need for wholistic tools to...
