The increasing penetration of the real world with embedded and globally networked sensors enables the formation of a Web of Things (WoT), where high-level state information derived from sensors is embedded into Web representations of real-world entities (e.g. places, objects). A key service for the WoT is searching for entities which exhibit a certain(More)
—The increasing penetration of the real world with embedded and globally networked sensors leads to the formation of the Internet of Things, offering global online access to the current state of the real world. We argue that on top of this real-time data, a Web of Things is needed, a software infrastructure that allows the construction of applications(More)
—We are observing an increasing trend of connecting embedded sensors and sensor networks to the Internet and publishing their output on the Web. We believe that this development is a precursor of a Web of Things, which gives real-world objects and places a Web presence that not only contains a static description of these entities, but also their real-time(More)
It is clear that the reconfiguration of mobile SDR terminals requires complex interactions between the mobile terminal and the network or application server entities. To enable mobile devices to utilize different radio access technologies and communication protocols depending on the requested application QoS and to enable development of context aware(More)
A new computing era after Mainframes, PC's and mobiles is becoming more and more anticipated since the beginning of the 21st century. This new era is often described with several confusing terms such as pervasive, ubiquitous, ambient or context-aware computing. However, there is a common characteristic behind all these projections: They are all based on a(More)
Many ubiquitous computing applications so far fail to live up to their expectations. While working perfectly in controllable laboratory environments , they seem to be particularly prone to problems related to a discrepancy between user expectation and systems behavior when released into the wild. This kind of unwanted behavior of course prevents the vision(More)
We present a novel approach for the temporal synchronization of multiple videos which is based on cross-correlating bit rate profiles. The proposed scheme determines the temporal offset without major restrictions on viewing angles, camera properties and camera motion. We propose two extensions of the basic algorithm which reduce the influence of camera(More)
We propose a novel framework for Cooperation Among Mobile Prosumers (CAMP) that aims at establishing semantic relations between multimedia content acquired by mobile users, focussing especially on audiovisual media. We discuss the basic properties of such a system and describe a number of possible applications. We also address technical requirements and(More)
