			<content:encoded><![CDATA[The paper title is &quot;On Optimal Tag Placement for Indoor Localization&quot; and the authors are Stephan Wagner, Marcus Handte,&nbsp;Marco Zuniga,&nbsp;Pedro José Marrón.
Abstract:&nbsp;Indoor localization based on signal strength fingerprinting has received significant attention from the community. This method is attractive because it does not require complex hardware beyond a simple radio transmitter. However, its main limitation is the inaccuracy caused by the variability of the signal strength. When applied to the localization of people, the signal variability can be attributed to three main sources: environmental dynamics (movement of people or objects), movement of transceiver (changes in the position and/or orientation of the transceivers) and body effects (distortion of the wireless signal due to body absorption). Our work focuses on the impact of the last two sources and provides two important contributions. First, we present an analysis to quantify the effects of antenna disorientation and transmitter misplacement. For the RFID system used in our work, these effects can decrease the localization accuracy by up to 50%. Motivated by these results, we identify parts of the human body where tags are less affected by unintentional movements. Second, we describe how multiple transmitters can be used to overcome the absorption effects of the human body. Our results indicate that four transmitters provide a reasonable trade-off between accuracy and hardware cost. We validate our findings through an extensive set of measurements gathered in a home environment. Our tests indicate that by following the guidelines proposed in this paper, the localization accuracy can improve from around 20% up to 88%.]]></content:encoded>

			<content:encoded><![CDATA[The paper title is &quot;Enabling Energy-Efficient Context Recognition with Configuration Folding&quot; and the authors are Muhammad Umer Iqbal, Marcus Handte, Stephan Wagner, Wolfgang Apolinarski, Pedro José Marrón.
Abstract:&nbsp;Existing context recognition applications for personal mobile devices are usually fine-tuned to recognize the set of characteristics required to support a particular user task. Outside of a laboratory environment, however, users are often involved in multiple tasks at a time which requires the simultaneous execution of several applications. Yet, due to the energy constraints of most personal mobile devices this approach is inherently limited in scale. In this paper, we show how this problem can be avoided by applying a component-based approach to application development and execution. We present a component system that enables developers to build individual applications in isolation without compromising runtime efficiency. When applications are executed simultaneously, the component system applies a novel technique called configuration folding to automatically remove redundancies. Our experimental evaluation of configuration folding shows that it can save up to 48 percent of energy when applied to a music and a speech detection application, thus, amortizing energy costs after a few seconds of execution.

The demonstration is titled &quot;Configuration Folding: An Energy Efficient Technique for Context Recognition&quot;. The authors are Muhammad Umer Iqbal, Marcus Handte, Stephan Wagner, Wolfgang Apolinarski, Pedro José Marrón.
Abstract:&nbsp;This demonstration presents configuration folding, a novel technique which enables the energy efficient execution of multiple context recognition applications on a personal mobile device. Configuration folding achieves energy efficiency by identifying and removing the redundant functionalities in different context recognition applications at runtime. The demonstration shows the effectiveness of configuration folding. To do this, we have implemented two non-trivial sound-based context recognition applications that are able to detect speech and music. During the demonstration, we will execute these applications with folded and unfolded configurations and we will show how the resulting energy gains can be measured. Furthermore, we present how similar applications can be built by means of composition.]]></content:encoded>

			<description>Paper title: &quot;A Peer-based Approach to Privacy-Preserving Context Management&quot;
Authors: Wolfgang Apolinarski, Marcus Handte, Danh Le Phuoc, Pedro José Marrón</description>
			<content:encoded><![CDATA[The short paper called &quot;A Peer-based Approach to Privacy-Preserving Context Management&quot; was presented at the&nbsp;CONTEXT conference (CONTEXT 2011) in Karlsruhe, Germany. It describes how the PECES Middleware covers context&nbsp; management in a privacy-preserving manner while showing that it is capable to run on resource-constrained devices such as sensors. The conference was held for the 7th time, this year at the KIT in&nbsp;Germany.
Abstract:
Providing adequate support for context acquisition and management is a non-trivial task that complicates application development. To mitigate this, existing middleware systems rely on a centralized context service that manages the context of all devices located within a certain area. However, in many cases, centralized context management impacts privacy as it requires users to share their context with a possibly untrusted device. In this paper, we show how this problem can be avoided by a peer-based approach to context management. To validate the approach, we have implemented it on top of the BASE middleware and used it extensively in the PECES European research project. The evaluation shows that given a customizable implementation, the approach provides high flexibility while being suitable for a broad spectrum of devices.]]></content:encoded>

			<description>Paper title: &quot;Supporting Environment Configuration with Generic Role Assignment&quot;
Authors: Wolfgang Apolinarski, Marcus Handte, Pedro José Marrón</description>
			<content:encoded><![CDATA[The paper called &quot;Supporting Environment Configuration using Generic Role Assignment&quot; was presented at the Intelligent Environments conference (IE'11) in Nottingham. It describes mechanisms used in the PECES project that can be used to configure environments using context information. The conference was held for the 7th time, this year at the Nottingham Trent University in the United Kingdom.
Abstract:
Due to the fact that distant objects are often less relevant to an application than objects in the proximity, middleware systems for pervasive computing typically exploit locality to improve efficiency. To do this, they configure the environment by introducing logical boundaries that reduce the number of interacting devices. Yet, in cases where applications require the interaction with distant objects, the boundaries become an artificial barrier that must be overcome by supplemental mechanisms. In this paper, we show how this problem can be avoided by using role assignment as a generic mechanism for environment configuration. To do this, we first derive the requirements for configuring a pervasive computing environment. We discuss how these requirements can be met by means of role assignment. To evaluate the approach, we present a prototypical implementation which we use to quantify the resulting overheads. The results indicate that role assignment enables a more flexible definition of boundaries at a low cost.]]></content:encoded>

			<content:encoded><![CDATA[Currently, electricity is mainly generated by a few far-off high-capacity generators. However, due to environmental concerns, electrical energy is increasingly being produced by small scale generators located close to the point-of-use. This decentralized model for energy generation will bring with it many challenges to maintain grid robustness. The NOBEL project (<link http://www.ict-nobel.eu/>www.ict-nobel.eu</link>) takes a radical approach towards addressing these issues. We design and realize an IT infrastructure where consumers also become producers of electricity, as well as information, termed &quot;prosumers&quot; within the NOBEL project.
One promising way to investigate this is to consider a market-driven approach as a tool to integrate the users and enable both information exchange and prosumption behaviour. For instance, a surplus of energy generated from a rooftop photo-voltaic panel of one user, could be used to cover partially the demand of another user. In NOBEL, we investigate the impact of such a small scale market on energy efficiency of a neighborhood.
In order to better conduct our research, we would like to better understand how a small scale market could affect your interests.
Therefore a survey has been initiated currently. You can find surveys for private consumers, business consumers and public utitlities.
The survey can be found <link http://web.ict-nobel.eu:91/interest-group/interest-group/survey>here</link>.

			<description>The paper &quot;Boreas: Efficient Synchronization for Scalable Emulation of Sensor Networks&quot; by Robert Sauter, Richard Figura, Olga Saukh and Pedro José Marrón has been accepted at IEEE MASS 2011.</description>
			<content:encoded><![CDATA[The 8th IEEE&nbsp;International Conference on Mobile Ad Hoc and Sensor Systems (<link http://mass2011.upv.es/>IEEE MASS 2011</link>) will be held in Valencia, Spain on October 17-22. The acceptance rate is 20%.
The paper investigates efficient synchronization algorithms to increase the speed and scalability of cycle-accurate wireless sensor network emulation.
Paper Abstract:
Cycle-accurate emulation of sensor networks allows a detailed analysis of platform target code for development and evaluation. However, the high overhead incurred by providing the necessary fidelity limits the size of the emulated networks considerably. The use of multiple cores provided by modern hardware can significantly improve the speed of emulation but requires synchronization algorithms to preserve causality. Based on the well-known multithreaded emulator Avrora, we investigate a number of synchronization methods including an algorithm that does not require any locks to improve the performance. We show that both the speed and the scalability can be significantly improved without sacrificing correctness. Additionally, we evaluate the impact of modern CPU technologies such as simultaneous multithreading on emulation performance.]]></content:encoded>

			<description>Paper title: &quot;Context-dependent Smart Space Formation in PECES&quot;
Authors: Wolfgang Apolinarski, Marcus Handte, Pedro José Marrón</description>
			<content:encoded><![CDATA[The paper &quot;Context-dependent Smart Space Formation in PECES&quot; was presented at the KUVS Fachgespräch &quot;Verteilte Systeme in Smart Spaces&quot; which was held at the first of July&nbsp;at the TU Darmstadt. There, different concepts for the building, configuration and using of Smart Spaces were discussed. Additionally, the term &quot;Smart Space&quot; was discussed and different models of describing the meaning of the term were presented.
Abstract:
Most existing middleware systems for pervasive computing enable the interaction between devices that are located within a limited spatial area such as a room or a building. Devices residing in this area can freely cooperate, for example, by sharing resources through service abstractions. In the past, this approach has been proven to be suitable for enabling smart meeting or class rooms. The PECES middleware extends this approach by building upon role assignment as a more expressive and uniform mechanism to form groups of interacting devices. Instead of fixing group formation to a particular spatial area, role assignment enables applications to form dynamic groups in a context-dependent manner. The groups can be composed hierarchically to allow the interaction of devices at distant locations connected via the Internet.]]></content:encoded>

			<description>The paper &quot;Link Quality Ranking: Getting the Best out of Unreliable Links&quot; by Marco Zuniga, Izabella Irzynska, Jan-Hinrich Hauer, Thiemo Voigt, Carlo Alberto Boano and Kay Römer has been presented at IEEE DCOSS 2011 in Barcelona, Spain.</description>
			<content:encoded><![CDATA[Link quality estimation has been an active area of research within the wireless sensor network community. It is now well known that the estimation of reliable links requires few sample packets – less than 10, while the estimation of unreliable links requires many more – above 50. In scenarios where unreliable links are ubiquitous, and a rapid transfer of data is needed, traditional estimation techniques are not a viable option. In such scenarios, it is instead sufficient to identify the best link available at any given time. Within this context, we propose Link Quality Ranking (LQR), a mechanism that identifies the best link available when only unreliable links are present. Our testbed results indicate that with one sample packet, the delivery rate of LQR –with respect to the best link available– is above 93%. With 10 sample packets, the performance is above 96%.]]></content:encoded>
