abstract = {Recent developments in networking hardware and software-defined networking have
enabled full distribution of network control to reduce control latency and
increase reliability. However, both, hardware and software of current white-box
networking hardware are highly heterogeneous, which limits the deployment and
operation of switch-local control applications. Furthermore, switch-local
control raises yet unconsidered security concerns. In this paper, we present
our concept of in-forward-element processing, which leverages the open access
to the control plane of white-box networking hardware to deploy control logic
directly onto switches. We combine local control applications with lightweight
virtualization to cope with networking hardware heterogeneity and to achieve
required isolation properties and ease of management. Beyond distributed
network control, we show this scheme is also beneficial for implementing
switch-local virtual network functions (NFV), processing packets. Highlighting
the practicability of the concepts, we provide an overview of the current
white-box networking hardware and software landscape and their compatibility
with lightweight virtualization technologies. To this end, we perform an
empirical evaluation of NOS-virtualization combinations on such hardware and
compare the results with respect to incurring virtualization overhead.},

abstract = {Distributed Complex Event Processing (DCEP) is a paradigm to infer the
occurrence of complex situations in the surrounding world from basic events
like sensor readings. In doing so, DCEP operators detect event patterns on
their incoming event streams. To yield high operator throughput, data
parallelization frameworks divide the incoming event streams of an operator
into overlapping windows that are processed in parallel by a number of operator
instances. In doing so, the basic assumption is that the different windows can
be processed independently from each other. However, consumption policies
enforce that events can only be part of one pattern instance; then, they are
consumed, i.e., removed from further pattern detection. That implies that the
constituent events of a pattern instance detected in one window are excluded
from all other windows as well, which breaks the data parallelism between
different windows. In this paper, we tackle this problem by means of
speculation: Based on the likelihood of an event's consumption in a window,
subsequent windows may speculatively suppress that event. We propose the
SPECTRE framework for speculative processing of multiple dependent windows in
parallel. Our evaluations show an up to linear scalability of SPECTRE with the
number of CPU cores.},

abstract = {Angetrieben durch die stetig voranschreitende Digitalisierung gewinnt das
Internet der Dinge (engl. IoT) immer mehr an Bedeutung. Im IoT werden
technische Ger{\"a}te mit unterschiedlichen Sensoren ausgestattet und miteinander
vernetzt. Dadurch werden neuartige Anwendungen beispielsweise im Bereich
E-Health erm{\"o}glicht, in denen Sensordaten miteinander kombiniert und so in
h{\"o}herwertige Informationen umgewandelt werden. Die von diesen Anwendungen
abgeleiteten Informationen verraten viel {\"u}ber den Nutzer und m{\"u}ssen daher
besonders gesch{\"u}tzt werden. H{\"a}ufig hat der Nutzer allerdings keine Kontrolle
{\"u}ber die Verarbeitung seiner Daten, ganz davon zu schweigen, dass er das Ausma{\ss}
und die Art der daraus ableitbaren Informationen nicht ermessen kann.
In diesem Artikel stellen wir daher einen neuartigen Kontrollmechanismus vor,
der private Informationen im IoT sch{\"u}tzt. Anstelle von abstrakten
Datenschutzregeln f{\"u}r einzelne Sensoren definiert der Nutzer Muster, die es zu
sch{\"u}tzen gilt. Ein Muster kann beispielsweise eine Kombination aus Messwerten
sein, die auf eine bestimmte Krankheit schlie{\ss}en lassen. Der Nutzer definiert
die zu verheimlichenden Informationen nat{\"u}rlichsprachlich, und ein
Dom{\"a}nenexperte setzt diese in formale Regeln um. Sind diese Regeln zu
restriktiv, so kann die Anwendung ihre angedachte Funktionalit{\"a}t nicht
erbringen. Daher muss bez{\"u}glich der Servicequalit{\"a}t ein Kompromiss zwischen
gew{\"u}nschter Privatheit und ben{\"o}tigter Funktionalit{\"a}t gefunden werden.},

abstract = {Networked control systems (NCS) have attracted considerable attention in recent
years. While the stabilizability and optimal control of NCS for a given
communication system has already been studied extensively, the design of the
communication system for NCS has recently seen an increase in more thorough
investigation. In this paper, we address an optimal scheduling problem for a
set of NCS sharing a dedicated communication channel, providing performance
bounds and asymptotic stability. We derive a suboptimal scheduling policy with
dynamic state-based priorities calculated at the sensors, which are then used
for stateless priority queuing in the network, making it both scalable and
efficient to implement on routers or multi-layer switches. These properties are
beneficial towards leveraging existing IP networks for control, which will be a
crucial factor for the proliferation of wide-area NCS applications. By allowing
for an arbitrary number of concurrent transmissions, we are able to investigate
the relationship between available bandwidth, transmission rate, and delay. To
demonstrate the feasibility of our approach, we provide a proof-of-concept
implementation of the priority scheduler using real networking hardware.},

This promises to provide a multitude of benefits to the users, for example in
the management of natural disasters or in community empowerment. However,
current social sensing services depend on Internet connectivity since the
services are deployed on central Cloud platforms. In many circumstances,
Internet connectivity is constrained, for instance when a natural disaster
causes Internet outages or when people do not have Internet access due to
economical reasons. In this paper, we propose the emerging Fog Computing
infrastructure to become a key-enabler of social sensing services in situations
of constrained Internet connectivity. To this end, we develop a generic
architecture and API of Fog-enabled social sensing services. We exemplify the
usage of the proposed social sensing architecture on a number of concrete use

to drastically reduce the quality of the simulation. We therefore proposed
approaches utilizing a remote server and the Reduced Basis Method (RBM) to
generate a reduced model of the simulation.
In our demo, we demonstrate the effectiveness of our approaches for mobile
simulations. Our demo consists of two devices, a mobile device and a server.
Both devices are connected via wireless network. The mobile device visualizes
the result of a complex computation. Parameters of the simulation are effected
by sensors of the mobile device. The user can choose between computing on the
mobile device, computing solely on the server, or computing using our approach.},

abstract = {Currently, various hardware and software companies are developing augmented
reality devices, most prominently Microsoft with its Hololens. Besides gaming,
such devices can be used for serious pervasive applications, like interactive
mobile simulations to support engineers in the field. Interactive simulations
have high demands on resources, which the mobile device alone is unable to
satisfy. Therefore, we propose a framework to support mobile simulations by
distributing the computation between mobile device and a remote server. For the
computation of parameter-dependent solutions of the simulation, we use the
reduced basis method, which allows to drastically reduce the computation time
and energy consumption. We present three approaches for the distributed
execution of the reduced basis method between mobile device and server.
Evaluations show that we can speed-up the numerical computation to over 131
times while using 73 times less energy compared to offloading everything to a
server.},
