Item type:Publication, Access status: without files , Paint it black - Increase WSN energy efficiency with the right housing(Association for Computing Machinery (ACM), 2015-11-01); ; ; It is a well-known fact that Wireless Sensor Networks (WSNs) that are exposed to real environmental conditions suffer from harsh temperatures. Yet, the temperature does not only have negative impact as the energy efficiency of processing units benefits from higher temperatures. The minimal voltage for correct operation of CMOS circuits is bounded by the temperature. Thus, temperature-dependent undervolting schemes for WSN nodes have been proposed in the past to extend the network lifetime. However, not much thought has been given into directly inuencing the most relevant factor: Temperature. In this work we look at the inuence of various WSN housings onto the temperature profile of WSN nodes and quantify the energy saving potential of choosing the right housing.Publicationtype: Conference Paper63 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Minimising the entry effort in experimenting with WSN testbeds to perform heterogeneous research(Association for Computing Machinery (ACM), 2015-11-01); ; ; Testbeds play a crucial role in evaluating novel protocols, algorithms, and applications in controlled, but realistic envi-ronments. These testbeds are mainly used by researchers to realize diverse application environments, which are not real-istic to be achieved in simulated environments (e.g., lossy channels in Wireless Sensor Networks (WSN)). Most re-searchers, especially bachelor or master students spend a large portion of their time familiarizing themselves and set-ting up test beds before performing the actual research work. This portion of time, when considering the overall time for such work (e.g., 6 months for a masters thesis), forms a major part compared to the time spent on designing and developing protocols and algorithms (i.e., the focus of re-search). Therefore, to minimize the aforementioned entry effort in using testbeds for experiments, we have setup a testbed called the Versatile Experiment Platform for Sensor Networks (VEPSNet), which has a common Linux based en-vironment with a homogeneous backend to collect data and process results allowing researchers to spend their quality time in the actual research work. In this paper, we provide details of the VEPSNet highlighting how this testbed is used to perform research in the area of WSN.Publicationtype: Conference Paper155
