abstract = {Wired field buses have proved their effectiveness to support Cyber-Physical Systems (CPS). However, in avionics, for ease of deployment, or for new functionality featuring mobile devices, there is a strong interest for wireless solutions. Low-power wireless protocols have been proposed, but requirements of a large class of CPS applications can still not be satisfied. This paper presents Time-Triggered-Wireless (TTW), a distributed low-power wireless system design that minimizes energy consumption and offers end-to-end timing predictability, adaptability, reliability, low latency. Our evaluation shows a reduction of communication latency by a factor 2x and of energy consumption by 33-40% compared to state-of-the-art approaches. This validates the suitability of TTW for wireless CPS applications and opens the way for implementation and real-world experience with industry partners.},

abstract = {Many applications such as autonomous swarming drones and system services like data replication need to exchange data among many or all nodes in a network. However, wireless many-to-many broadcast has thus far only been studied theoretically or in simulation, and practical solutions hardly meet the requirements of emerging applications, especially in terms of latency. This paper presents Mixer, a communication primitive that provides fast and reliable many-to-many broadcast in dynamic wireless multi-hop networks. Mixer integrates random linear network coding with synchronous transmissions to simultaneously disseminate all messages in the network. To deliver the performance gains our approach enables, we design Mixer's protocol logic in response to the physical-layer characteristics and the theory of network coding. First results from testbed experiments demonstrate that, compared with the state of the art, Mixer is up to 65% faster and reduces radio-on time by up to 50%, while providing a message delivery rate above 99.9%.},

abstract = {Experimental research in low-power wireless networking lacks a reference benchmark. While other communities such as databases or machine learning have standardized benchmarks, our community still uses ad-hoc setups for its experiments and struggles to provide a fair comparison between communication protocols. Reasons for this include the diversity of network scenarios and the stochastic nature of wireless experiments. Leveraging on the excellent testbeds and tools that have been built to support experimental validation, we make the case for a reference benchmark to promote a fair comparison and reproducibility of results. This abstract describes early design elements and a benchmarking methodology with the goal to gather feedback from the community rather than propose a definite solution.},

We present Mixer, an all-to-all communication scheme that enables all nodes in a multi-hop low-power wireless network to exchange sizable packets with one another. Mixer's design integrates synchronous transmissions with random linear network coding, harnessing the broadcast nature of the wireless medium.

We present an automated configuration approach based on simulated annealing to overcome this problem. A preliminary evaluation based on two testbeds shows that our approach can find near-optimal solutions within at most a few hours. We believe our approach can facilitate the widespread adoption of controlled interference experiments by the sensornet community.},

abstract = {Traditional low-power wireless protocols maintain distributed network state to cope with link dynamics. Modeling the protocol operation as a function of network state is difficult as the state is frequently updated in an uncoordinated fashion. Recent protocols use synchronous transmissions (ST): multiple nodes send simultaneously towards the same receiver, as opposed to pairwise link-based transmissions (LT). ST enable efficient multi-hop protocols with little network state.

We studied whether ST in Glossy enable simple yet accurate protocol modeling [10]. Based on extensive testbed experiments and statistical analyses, we found that: (i) unlike LT, packet receptions and losses with ST largely adhere to a sequence of independent and identically distributed (i.i.d.) Bernoulli trials; (ii) this property greatly simplifies accurately modeling ST-based protocols, as we demonstrated by obtaining model errors below 0.25% in energy for the Glossy-based Low-Power Wireless Bus (LWB).},

abstract = {Developing, testing, debugging, and evaluating communication protocols for low-power wireless networks is a long and cumbersome task. Simulators can be helpful in the early stages of development, but their models of hardware components and the wireless channel are often rather simplistic and hence cannot substitute experiments on real sensor node platforms. The resources available on common platforms are however very limited, and so are the possibilities for non-intrusive debugging and testing. With most existing testbeds it is only possible to collect information from the serial port, which requires adding highly intrusive logging statements that alter the timing behavior of the software running on the nodes. This is particularly detrimental to the operation of time-critical components, such as radio drivers, media access control (MAC) protocols, and certain flooding protocols [2], hindering their testbed-assisted development.},

abstract = {We present the low-power wireless bus (LWB), a simple yet efficient communication support for low-power wireless networks. The LWB maps different communication demands onto fast Glossy network flooding, effectively turning the wireless network into a bus-like infrastructure. The LWB requires no information of the network topology, thus drastically reducing the control overhead of common solutions such as route maintenance, and natively supports many-to-many communication and mobile nodes in addition to more traditional static, one-to-many scenarios. For instance, experiments on a 90-node testbed show that on average the LWB reduces packet loss by a factor of 231 and energy consumption due to communication by a factor of 11 compared to a state-of-the-art many-to-many routing protocol.},

abstract = {The field of Wireless Sensor Networks (WSNs) is now in a stage where serious applications of societal and economical importance are in reach. For example, it is well known that the global climate change dramatically influences the visual appearance of mountain areas like the European Alps. Very destructive geological processes may be triggered or intensified, impacting the stability of slopes, possibly inducing landslides. Unfortunately, the interactions between these complex processes is poorly understood. Therefore, one needs to develop wireless sensing technology as a new scientific instrument for environmental sensing under extreme conditions. Large variations in temperature, humidity, mechanical forces, snow coverage, and unattended operation play a crucial role in long-term deployments. We argue that, in order to significantly advance the application domain, it is inevitable that sensor networks be created as a quality scientific instrument with known and predictable properties, and not as a research toy delivering average observations at best. In this paper, key techniques for achieving highly reliable, yet resource efficient wireless sensor networks are discussed on the basis of productive wireless sensor networks measuring permafrost processes in the Swiss Alps.},

abstract = {We analyze push and pull for data collection in wireless sensor networks. Most applications to date use the traditional push approach, where nodes transmit sensed data immediately to the sink. Using a pull approach, nodes store the data in their local flash memory, and only engage in communication during dedicated collection phases. We show how one can transform an existing push-based collection protocol into a pull-based one, and compare the power consumption of both approaches on a 35-node testbed. Our results show that substantial energy gains are possible with pull, provided that the application can tolerate a long latency.},

abstract = {Communication stacks are composed of distinct layers that, in principle, operate independently and interact through well-defined interfaces. However, resource constraints in sensor networks typically necessitate optimizations, leading to implicit assumptions and dependencies among layers (e.g., a collection protocol assumes the MAC protocol provides sufficient bandwidth). These dependencies are often tracked manually, yet become extremely complex as protocols evolve and requirements change. We propose to model assumptions and dependencies explicitly, as constraints on protocol parameters. This allows for using standard tools to generate feasible protocol configurations. We demonstrate the effectiveness of our approach using the example of FTSP running on top of a low-power listening MAC protocol.},

abstract = {Synchronization accuracy and energy efficiency are two of the most important requirements of a synchronization protocol for wireless sensor networks (WSNs). Typically, synchronization protocols for WSNs like FTSP rely on periodic message exchange in order to achieve a sufficient level of accuracy. A higher accuracy therefore comes at the expense of an increased energy consumption. In this paper, we introduce an analytic framework aimed at analyzing how accuracy and energy consumption are affected by the synchronization period and the radio duty cycle, using the example of FTSP running on top of a low-power listening (LPL) MAC protocol. The model exposes the hidden dependencies between protocol parameters and application requirements, which allows for using standard tools to generate feasible as well as optimal protocol configurations.},

year  = {2009},

date = {2009-08-01},

abstract = {Wireless sensor networks are concerned with resource and performance constraints. In the light of these constraints, sensor network protocols must operate efficiently and effectively at all times. This applies in particular to the medium access control (MAC) protocol, which dictates to a large extent the energy consumption of a sensor node by controlling the use of the radio transceiver. Moreover, it determines the timing of communication among neighboring nodes and thus per-hop latency and per-hop reliability. To achieve the best possible performance, the MAC protocol must be configured

with appropriate parameters and automatically adapted to changes in network conditions and application requirements.

This thesis presents a novel system for automatic optimization and adaptation of sensor network MAC protocols. It adapts the protocol parameters at runtime to ensure optimal performance and compliance with the application requirements. The optimization approach is based on constraint programming and optimizes multiple objectives simultaneously. The approach is applied in a case study to X-MAC [9], a flexible and widely used MAC protocol for sensor networks. Experimental results obtained from a small-scale network of real sensor nodes show that the proposed

system keeps MAC protocol performance close to the optimum under varying network conditions and different application requirements.},

abstract = {Der effektive Einsatz von Sensornetzwerken setzt eine besonders hohe Lebensdauer der batteriebetriebenen Sensormodule voraus. In der Vergangenheit wurden deshalb zahlreiche energieeffiziente Routingprotokolle für Sensornetze entwickelt. Die überwiegende Mehrheit dieser Protokolle geht dabei von einer maschenartigen Netzwerktopologie aus. Für bestimmte Anwendungen hingegen, wie beispielsweise der sensorbasierten Betriebsüberwachung von Ölpipelines, ist eine lineare Anordnung der Sensormodule inhärent. Aus diesem Grund stellt der vorliegenden Artikel das ,,Minimum Energy Relay Routing“ (MERR)-Protokoll vor, ein speziell für lineare Sensornetzwerke entwickeltes Routingprotokoll. Es werden konventionelle Routingstrategien besprochen und der Aufbau von Routingpfaden charakterisiert, entlang derer die aufzuwendende Energie minimal ist. Die Ergebnisse von stochastischen Untersuchungen und Simulation zeigen, dass MERR für praktisch relevante Sensoranordnungen nahe am Optimum arbeitet und im Vergleich zu existierenden Ansätzen erhebliche Energieeinsparungen erzielt. },
