Ambient networks (AN) project focuses on the convergence of heterogeneous networks over different domains. The aim (among others) is to facilitate co-operation, mobility support and multi-access between networks and terminals. One of the most important goals is to integrate the different AN-concepts together for validation. This paper presents an integrated(More)
Tackling the major Internet security, scalability and mobility problems without essentially changing the existing Internet architecture has turned out to be a very challenging task. The overlay routing approaches fortunately seem to offer a sound way to mitigate most of these issues. Basically, they decouple the end-point identifiers from locators by(More)
Ambient Networks concentrates on the co-operation of heterogeneous networks over multiple domains and accesses. One of the main goals of the project is the integration of developed concepts for validation purposes. This paper presents a performance analysis on the integration of mobility triggering and Host Identity Protocol (HIP) based mobility on the(More)
This demo presents a Machine-to-Machine (M2M) service platform running on an OpenStack cloud environment. Access to this platform is secured with authentication based on 3GPP standardized Generic Bootstrapping Architecture (GBA). The M2M network in this testbed consists of Raspberry Pi gateways and resource-constrained devices such as Arduinos. These(More)
In the last years multimedia processing applications have gained more and more importance in the field of mobile and hand-held devices, requiring dedicated hardware platforms characterized by high performance computation capabilities with reduced area occupation and low power consumption. 2D graphics and signal processing applications in general benefit(More)
End-to-end encryption is becoming the norm for many applications and services. While this improves privacy of individuals and organizations, the phenomenon also raises new kinds of challenges. For instance, with the increase of devices using encryption, the volumes of outdated, exploitable encryption software also increases. This may create some distrust(More)
Path metric computation in Viterbi decoders is a crucial task where previously computed path metrics are used as input values. If an area-efficient decoder is preferred, mapping the Viterbi algorithm onto reduced computational resources becomes attractive. This implies a need for path metric storage and an interconnection network between parallel(More)
