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 realtime data, a Web of Things is needed, a software infrastructure that allows the construction of applications(More)
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)
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: Ubiquitous Computing. A common characteristic behind this approach is that, it is based on a substantially more flexible system understanding, whereby the thought of the system as a tool moves into the background and the(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)
Cross-correlation is a classical similarity measure with broad applications in multimedia signal processing. While it is robust against uncorrelated noise in the input signals, it is severely affected by systematic disturbances which lead to biased results. To overcome this limitation, we propose in this paper consensus-based cross-correlation (ConCor) to(More)
Consensus-based Cross-correlation (ConCor) is a recently presented algorithm for robust synchronization of noisy and corrupted signals. ConCor has a number of interdependent parameters that need to be set correctly to guarantee good performance. In this paper we analyse the effects of the individual parameters on ConCor’s behaviour and performance. As a(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 realworld objects and places a Web presence that not only contains a static description of these entities, but also their real-time(More)
