Abstract:
Wireless sensor networks (WSNs) suffer from resource
limitations, high failure rates and faults caused by the lossy nature
of wireless communication. This can lead to situations, where nodes
lose synchrony and programs reach arbitrary states. Traditional
approaches to fault tolerance like fault masking or global resets are
not feasible for WSNs. Applying the concepts of self-stabilisation to
achieve fault tolerance is a promising concept. However, the majority
of self-stabilising algorithms found in the literature is based on
models not suitable for WSNs. This paper proposes a
problem-independent transformation for algorithms that stabilise
under the central daemon scheduler such that they meet the demands of
a WSN. Furthermore, a comparison with transformers from the
literature is made through a series of simulations. Finally, the
proposed transformer is evaluated with a real sensor network in a
field test.

Abstract:
A new data monitoring method for wireless sensor
networks is
introduced. The method combines geographic hash tables
with
in-network aggregation. Queries are processed in regions, whose
sensor nodes collect their values in nodes close to a determinated
location within the region, where they can easily be requested from
outside. The method is robust against node failures and movements and
generates very little network traffic. This is confirmed by various
simulations.

Abstract:
The accuracy of link-quality estimators (LQE) is
mission-critical in
many application scenarios in wireless sensor
networks (WSN), since
the link-quality metric is used for routing
decisions or neighborhood
formation. Link-quality estimation must
offer validity for different
timescales. Existing LQEs describe and
approximate the current
quality in a single value only. This method
leads to a limited
accuracy and expressiveness about the presumed
future behavior of a
link. The LQE developed in this paper
incorporates four quality
metrics that give a holistic assessment of
the link and its dynamic
behavior; therefore, this research is an
important step to achieving
a higher prediction accuracy including
knowledge about the short- and
long-term behavior.

Abstract:
Energy-efficient transportation of periodical sensor
readings towards a single sink
in wireless sensor networks is a
challenging task. In general, two
data-gathering strategies exist:
on-demand and bulk data forwarding.
For both strategies, cross-layer
techniques are a promising approach,
where TDMA is tailored to the
underlying routing tree. Therefore,
different TDMA schemes are
compared regarding achievable throughput,
packet delay, and
energy-efficiency for various sampling rates and
scenarios. Existing
schemes perform well in dedicated topologies
only. The new and simple
TDMA scheme presented in this paper
outperforms its predecessors in
all scenarios under consideration.
These findings are substantiated by
both theoretical analysis and
extensive simulation.

Abstract:
Wireless Sensor Networks (WSNs) operate in an
unstable environment and thus are subject to arbitrary transient
faults. Self-stabilization is a promising technique to add tolerance
against transient faults in a self-contained non-masking way. A core
factor for the applicability of a given self-stabilizing algorithm is
its convergence time. This paper analyses the average stabilization
time of three algorithms commonly regarded as central building blocks
for WSNs. The analysis is accomplished with SelfWISE, a framework
providing programming abstractions for selfstabilizing algorithms.
The performed analysis considers the target models as well as network
size and density. This demonstrates the usability of SelfWISE for
evaluating selfstabilizing algorithms under a wide range of models.

Abstract:
TinyAID is a tool that supports automated
instrumentation and evaluation of TinyOS-based distributed
applications. Two types of instrumentations are provided: logging of
call chains and message flows within the network. TinyAID assists the
debugging process by post evaluation of the logged data. A main
benefit is the visualization component for representing traces in
their spatial and temporal order. The instrumentation and evaluation
concepts are evaluated in two case studies: the SelfWISE framework
and a selection of routing algorithms. Due to the automated process
of TinyAID the evaluation could be performed without a deeper
knowledge of the implementations under test. In the first case
TinyAID revealed a weakness in the TOSSIM random number generator.
The second case demonstrates the power of TinyAID to visualize the
quality of protocols in a unified manner, without any manual changes
to the specific source code.

Abstract:
This paper introduces SelfWISE, a framework for
enabling wireless sensor networks to be programmed in a
self-stabilizing manner. The framework eases the formal specification
of algorithms by abstracting from low-level details such as wireless
channel and hardwarespecific characteristics. SelfWISE consists of a
language for expressing self-stabilizing algorithms, a runtime
environment for simulating algorithms in wireless sensor networks,
and supporting tools. The hereby applied transformation of formally
described algorithms into the simulation environment preserves the
self-stabilizing properties. Development, evaluation, and debugging
of self-stabilizing algorithms is considerably facilitated by
utilizing SelfWISE.

Abstract:
In this paper an efficient TDMA slot assignment for
the many-to-one routing pattern in wireless sensor networks is
presented and analyzed. This assignment scheme is based on a simple
to implement heuristic, named spatial path-based reuse (SPR). By
considering several metrics, the superiority of this heuristic with
respect to energy consumption and runtime compared to proposals found
in the literature is demonstrated.

Abstract:
A particular class of data intensive wireless sensor
networks are those networks where sensors periodically measure data
with high rates. The focus of this work is on the efficient transport
of high volumes of sampled data through a multi-hop network with
limited resources using a routing tree. This paper analyzes TDMA
schemes for this purpose with respect to buffer usage and energy
consumption. In particular, it is shown, that classical TDMA schemes
are not optimal for tree-routing in data-intensive sensor networks.

Abstract:
This paper presents the design of a long-term
reliable data gathering service for many-to-one communication in
wireless sensor networks: all nodes send periodically delaytolerant
data to a single node. The service operates reliably despite strict
resource constraints, poor link qualities, and frequent disconnects.
This paper presents a novel protocol for gathering periodically
measured data including a solution for the wearleveling problem of
the EEPROM. Furthermore, theoretical limits of this approach based on
available bandwidth and local memory are provided. Finally,
preliminary results of an implementation of the service are
presented. In particular a detailed analysis of the energy
consumption during the different phases of this experiment is
provided.

Abstract:
Sensor networks are increasingly used for
applications in which sensors periodically measure data with high
sampling rates. The reliable transport of high volumes of sampled
data through a multi-hop network with limited resources requires
sophisticated algorithms. This paper presents a novel protocol for
this task that uses minimal energy, provides high throughput, and
requires only small amounts of additional buffer. The protocol is
based on a dynamic TDMA scheme and is robust against omission
failures.

Abstract:
Wireless sensor networks (WSNs) pose challenges not
present in classical distributed systems: resource limitations, high
failure rates, and ad hoc deployment. The lossy nature of wireless
communication can lead to situations, where nodes lose synchrony and
programs reach arbitrary states. Traditional approaches to fault
tolerance like replication or global resets are not feasible. In this
work, the concept of self-stabilization is applied to WSNs. The
majority of self-stabilizing algorithms found in the literature is
based on models not suitable for WSNs: shared memory model, central
daemon scheduler, unique processor identifiers, and atomicity. This
paper proposes problem-independent transformations for algorithms
that stabilize under the central daemon scheduler such that they meet
the demands of a WSN. The transformed algorithms use randomization
and are probabilistically self-stabilizing. This work allows to
utilize many known self-stabilizing algorithms in WSNs. The proposed
transformations are evaluated using simulations and a real WSN.

The paper compares two approaches for developing Web

for the vertical integration of TTP/A fieldbus
systems. High-level
abstractions are provided by application specific
interfaces,
generated from metadata describing fieldbus systems. In
contrast
standardised interfaces such as OPC XML DA only allow lower
levels of
abstractions. But these enable accessing the fieldbus system
from a
broad range of standard clients, while high-level abstractions
reflecting the application programmer's view on the system facilitate
the development of more specific clients and workflows.

Abstract:
Knowledge of neighboring nodes is a fundamental
requirement of many algorithms
in the field of wireless sensor
networks.
The neighborhood relation of nodes is defined by their
ability to
communicate directly and not by their proximity.
Due to the
temporal changes of the wireless channel, link qualities must
be
continuously estimated.
In this paper a new approach based on holistic
packet statistics is
presented.
Unlike existing estimation techniques
it forswears from squeezing a link's
characteristics into a single
value.
The benefit of this approach is substantiated by an evaluation
utilizing
real-world and synthetic data.

Abstract:
Long living and unattended deployments of wireless
sensor networks
requires fault-tolerant solutions.
Self-stabilizing
algorithms are providing these properties in an elegant and
verifiable way. Recently,
a lot of research has been performed to
determine appropriate means to
apply these promising technique
to
wireless sensor networks. In this paper the current state of the art
in this field is given.
Additionally, three major challenges are
presented for achieving self-stabilizing
sensor networks.

Abstract:
Support for developing energy-efficient applications
for wireless sensor
networks is still scarce.
In this paper a roadmap
of a combined hardware and software approach is
presented. The main
idea is
to collect state information and trace energy consumption of
an
application running in a testbed of
real sensor nodes.

Abstract:
The exploratory focus of the SomSed research field is
the
interdisciplinary research on self organizing mobile
sensor and
data networks. Since the founding of SomSed in 2007, great
progress in
scientific research has been
achieved and much practical knowledge has
been gathered using a prototype
network permanently installed. This
prototype network, from hereon referred to as CampusNet, is the basis
for
further investigations and offers the
possibility to perform long
term measurements in a large scale and real
environment. The scope of
this paper is
to outline the current status of the SomSed research
field and to
briefly discuss future developments.

Abstract:
In many application scenarios of wireless sensor
networks parts or the
whole network consist of mobile sensor
nodes.
Currently, no common platform is available. This paper describes a
project that has developed a mobile
sensor node, based on standard
components: a Crossbow IRIS mote and LEGO
MINDSTORMS NXT components,
i.e.,
motors and sensors.

Abstract:
The research field "Self organized mobile Sensor and
Data-networks" (SomSeD) is introduced. Its purpose is the in-
vestigation of Wireless Sensor Networks (WSN). It benefits from
interdisciplinary exchange between various institutes of the Hamburg
University of Technology (TUHH). Due to different design constraints
(such as energy-efficiency and package size) compared to well known
classical computer networks, all aspects of the development of WSNs
must be reconsidered. This paper describes the advantage of having
experts of various faculties both in computer science and electrical
engineering in a single research field. In addition to the
introduction of the participating institutes, the de-
ployment of a
WSN on the TUHH campus will be outlined.

Abstract:
Neighborhood relations are changing over time in
wireless sensor networks due to different hardware or environmental
effects. These effects and memory limitations require a balanced
neighborhood management to ensure agility, stability, symmetry, and
connectivity. The proposed neighborhood management protocol Mahalle
is optimized with regard to these four criteria. Agility and
stability are achieved by ALE, a new adaptive link estimator.
