Past Projects

REAP: Robuste, energieeffiziente drahtlose Sensornetze für realistische Außeneinsatzszenarien durch Adaption von Betriebs-Parametern (DFG: BU 3282/2-1)

Monitoring the changing environmental conditions allows to benefit from the systems dynamics. Realistic models for energy and reliability will be derived from these measurements. Combined with the knowledge about the characteristics of the nodes in the network, this information can, e.g., be used for routing decisions, task scheduling, and processing within the network.

INGA: Inexpensive Node for General Applications

INGA is an open source wireless sensor node for anything. INGA was developed at IBR (TU Braunschweig) as Inexpensive Node for General Applications and is used in numerous projects. The motivation to develop INGA was driven by the need for a reasonable, cheap and expandable node for several use cases.

 abstract = {Ballistocardiography (BCG) is the measurement of heart and cardiovascular related acceleration of the body. Due to the availability of inexpensive and small accelerometers, scientific interest in BCG increased in recent years. A variety of different measurement systems have emerged. Many of them lack on data quality, such as resolution and temporal precision. A deterministic timing behaviour is essential to produce meaningful results, especially when dealing with data from multiple sensors at once. We present a novel measurement system, which allows for parallel digital data acquisition in the presence of strict deterministic timing constraints. A dedicated server manages multiple measurement boards and acts as a data sink. All connected boards are synchronized, which renders all acquired data comparable in time. On each board, data from 4 parallel channels is pre-processed and time-stamped in Field Programmable Gate Array logic. The presented system enables distributed measurements and is scalable within the limitations of the available network. A field test with over 30 subjects proved the usability and reliability of the system, while all data are made available for the community and first results of this campaign are presented within this paper.},

Investigation & Mitigation of the Energy Efficiency Impact of Node Resets in RPL

@article{Kulau:AdHoc-Networks-2021,
 abstract = {Dependability is a keyword within the recent discussion about the operation of Wireless Sensor Network (WSN) as a vital part of the ever-growing Internet of Things (IoT). However, while focusing on, e.g., reliable routing it is often neglected that the energy supply is an important factor to enable dependable WSN, and thus IoT operation. Using the example of the Routing Protocol for Low power and Lossy Networks (RPL) we will show that a high operational capability is often at the expense of energy resources. Nevertheless, we will also show that this issue can be mitigated. While the resilience of RPL has been verified in a plethora of existing evaluations, the impact of simple node resets on the energy efficiency has not been investigated so far. However, resets may happen for a variety of reasons which are stated in this work as well. Thus, in the first part of this paper we examine the energy costs of resets in a RPL network. We show that such temporary node failures can have a serious impact on the network’s total energy usage depending on failure location and topology. As resets are common in real WSNs this work reveals an important weakness of RPL which can even be exploited for attacks. To mitigate this issue, in the second part of this paper we propose a hardening of RPL by maintaining a backup of the RPL state information in a non-volatile memory. Improvements as well as limitations of this approach and a mechanism for a seamless recovery are discussed and described in detail. Finally, the effectiveness and the characteristics of the proposed approach to harden RPL are evaluated extensively.},

 abstract = {While existing work focuses on the transceiver and the processing unit to increase the energy efficiency of wireless sensor nodes, it is missed that peripheral energy consumption may dominate that of the entire node. Related to Dynamic Voltage Scaling (DVS), even peripherals’ energy efficiency benefit from a downscaled voltage level, but different peripherals require different minimum voltage levels. With this demo we combine theory and practice to present the implementation of an algorithm weighing off the benefits of a downscaled voltage level against the switching overhead, e.g. for calculating an optimal peripheral voltage schedule.},

Energy-Efficient Voltage Scheduling of Peripheral Components on Wireless Sensor Nodes

 abstract = {Much effort has been put into optimizing the energy-efficiency of wireless sensor nodes, but existing work exclusively focuses on the transceiver and the processing unit. Nevertheless, the peripheral energy consumption may dominate that of the entire node. We introduce the concept of a dynamically scalable peripheral voltage supply: Even for peripheral devices, a lower voltage level leads to a lower energy consumption. Each peripheral requires a different minimum operating voltage, but switching the voltage level consumes energy as well. We combine theory and practice to present an algorithm weighing off the benefits of a downscaled voltage level against the switching overhead, i. e., for calculating an optimal peripheral voltage schedule. Our approach is capable of self-parameterization and has been implemented and tested on a prototype, saving up to 47\% of peripheral energy as compared to existing solutions.},
