%X Distributed sensing is commonly used to obtain accurate spectral information over a large area. More and more heterogeneous devices are being incorporated in distributed sensing with the aim of obtaining more flexible sensing performance at lower cost. Although the concept of combining the strengths of various sensing devices is promising, the question of how to compare and combine the heterogeneous sensing results in a meaningful way is still open. To this end, this paper proposes a set of methodologies that are derived from several spectrum sensing experiments using heterogeneous sensing solutions. Each of the solutions offers different radio frequency front-end flexibility, sensing speed and accuracy and varies in the way the samples are processed and stored. The proposed methodologies cover four fundamental aspects in heterogeneous sensing: (i) storing experiment descriptions and heterogeneous results in a common data format; (ii) coping with different measurement resolutions (in time or frequency domain); (iii) calibrating devices under strictly controlled conditions and (iv) processing techniques to efficiently analyse the obtained results. We believe that this paper provides an important first step towards a standardized and systematic approach of heterogeneous sensing solutions.

%U http://groups.winnforum.org/page/sdr-winncomm-2014-paper-store
%X In this paper, the Transceiver  Application Programming Interface (API)  scheduling according to a Time Division Duplex  (TDD) Long-Term Evolution (LTE) like  WaveForm (WF) is presented. The TDD LTE  mode has been chosen because of the  complexity of the User Equipment (UE)  Transmitter (Tx) Receiver (Rx) reversal. One by  one five use cases that a TDD LTE like WF  needs are presented and, in each use case figure,  the Transceiver API operations parameters are  detailed. This use cases exercise shows that the  Transceiver API can be successfully applied to a  TDD LTE like WF.

%X The current proliferation of unplanned wireless local area networks (WLANs) is creating the need for implementing different adaptation strategies to improve network performance under mutating and evolving interference scenarios. In this article, we envision a new solution for expressing and implementing high-level adaptation policies in WLANs, in contrast to the current approaches based on vendor-specific implementations. We exploit the hardware abstraction interface recently proposed by the wireless medium access control (MAC) processor (WMP) architecture and some flow-control concepts similar to the Openflow model for defining MAC adaptation policies. A simple control architecture for disseminating and activating new policies among multiple nodes is validated in an experimental testbed.

%X Abstract: Research on Dynamic Spectrum Access (DSA) has focused to a large extent on the reliable detection of signals at very low power levels, possibly even under the noise floor. However, many of those channels that are detected to be free are adjacent to used channels, with possibly very large power levels.As a result, the true DSA problem is not only reliable detection of free bands, but also robust operation next to used bands. In this demo we demonstrate an SDR RFIC which is robust against out-of-band interference. This robustness is achieved by improving the linearity of the SDR receiver significantly. The need for robustness is demonstrated in real time by showing the received constellation diagram of an 802.11af-like OFDM signal in the presence of a large out-of-band interferer. The wanted and interfering signal are received simultaneously by two generations of SDR RFIC’s, showing both the performance degradation caused by interference from adjacent bands and the improvement enabled by the robust receiver.

%X The purpose of this demonstration is to show handover with continuous service between two independent base-station entities belonging to different operators. The handover occurs without any link layer connection between the base-stations and without prior knowledge of base-station operating frequencies or channelization on the part of the receiver. To achieve this, the system employs a receiver-driven approach to the handover.

%X The IBBT iLab.t technology centre provides computing hardware, software tools and measurement equipment to support researchers and developers in building their ICT solutions, and in measuring the performance of these solutions. Among other things, the iLab.t hosts several generic Emulab-based wired test environments called the Virtual Walls, and two wireless test environments which are grouped under the name w-iLab.t. Until very recently, these wired and wireless test facilities each had their own history: they were deployed and maintained by a different group of people, were operated using different tools, and each had their own community of experimenters.   This paper provides insight on the origin and evolution of the Virtual Wall and w-iLab.t facilities. It explains how these facilities were federated, by using the best parts of both the OMF and Emulab frameworks. It discusses the benefits of our local federation as well as our future federation plans.

%X The w-iLab.t is a large-scale generic wireless experimentation facility. Over 260 wireless nodes are installed at two different locations. Every single wireless node is equipped with multiple wireless technologies, namely IEEE~802.15.4, Wi-Fi a/b/g(/n), and on some devices also Bluetooth. Additionally, w-iLab.t provides access to software defined radio platforms and also uses them to characterize the wireless environment during an experiment. The w-iLab.t flexibility and its tools enable experimenters to design and schedule a wide range of wireless experiments, and to collect and process results in a user-friendly way.

%T An Empirical Study of Urban 2.4 GHz RF Noise from the Perspective of a Body Sensor Network
%A Jan-Hinrich Hauer
%A Daniel Willkomm
%C London, UK
%X In the 2.4 GHz ISM band RF interference is becoming an ever-increasing problem. While there have been several attempts to mitigate the impact of RF interference on (body) sensor networks, e.g. via frequency hopping, it is often unclear how these solutions perform in different interference environments and when they are actually useful. This is not least due to a lack of knowledge about the characteristics of environmental 2.4 GHz RF noise as perceived by a BSN in realistic scenarios. Such knowledge would, for example, help to better understand the communication challenges in a BSN and derive design decisions for interference mitigation techniques. Our work targets this under explored area: we present the results from an urban measurement campaign, in which a mobile BSN collected about half a billion RF noise samples in various urban environments (park, campus, residential area, shopping street, urban transportation system). Our setup captured the entire 2.4 GHz band, on five different body positions simultaneously. Among other things, our results indicate that WLAN was the dominating source of 2.4 GHz RF noise, significant spectrum activity was typically detected during about 5% of the time, but there is a large variation among the scenarios, and, to detect the presence of RF interference the body position is of no of major importance, however, the difference in interference power measured at two different body positions is not negligible.

%X Cognitive radio has received considerable amount of attention as a promising technique to provide dynamic spectrum allocation. Wide-band spectrum sensing is the corner stone for cognitive radio to be functional. Most existing commercial sensing solutions lack either the required flexibility or speed. Software-defined radio (SDR) on the other hand offers very high flexibility and therefore becomes a common platform for CR implementation. Among various SDR platforms, the universal software-defined radio peripheral (USRP) gained broad popularity. This paper presents a real-time wide-band-capable spectrum sensing solution based on USRP. The concept of energy detection and the methodology for wide-band sensing are explained. Finally, the performance of the proposed sensing solution is verified and compared with another popular commercial sensing solution, Airmagnet.

%X We demonstrate a reconfigurable engine for multipurpose spectrum sensing within the cost and power constraints of mobile devices. The analog part builds up on the Scaldio reconfigurable analog front-end. The digital part is an innovative Digital Front-end for Sensing capable of performing a range of sensing algorithms, which has now been fully implemented as a chip. These components are integrated within one hardware setup, enabling real-time validation of the sensing engine. The setup is validated for DVB-T and LTE, two important candidates for future DySPAN networks, as well as for very fast spectrum sweeping.

%X Since the introduction of the Opportunistic Spectrum Access paradigm, focus has been on the development of sensing algorithms. Many of those techniques have been verified only through simulations. A small set of the techniques has been verified using off-the-shelf hardware, with limited capabilities, and spectrum analyzers with very good performance, however not realistic for low-power handheld solutions. In this paper, we propose sensing functionality for sensing of LTE and DVB-T signals. This functionality is then verified using a prototype RF front-end that is a realistic candidate for future Software Defined Radio (SDR) handheld solutions. The performance achieved with this front-end is also compared with the spectrum analyzer performance, for the same functionality. We conclude that the prototype achieves a sensing performance within 12dB of the performance achieved by the test equipment when using simple energy detection functionality. In the case of feature based sensing both systems achieve similar performance. In terms of sensitivity, the considered DVB-T sensing functionality achieves the target detection performance up to -102dBm with the sensing prototype over a bandwidth of 8 MHz and averaging 9 OFDM symbols.

%X Recent advances in wireless communication theory and semiconductor technology had tremendous positive effect on the usability of wireless. As a result, wireless is embedded in virtually every aspect of our life, and this trend is expected to continue to increase in the future. Unfortunately, the electromagnetic spectrum is a scarce resource. As the number of wireless applications grows, the same spectrum is reused over and over again, resulting in increased interference, which jeopardizes the prospect of wireless meeting its high expectations.  Dynamic Spectrum Access is one class of mechanisms proposed to mitigate this problem. It uses various technologies to adapt the operational parameters of wireless networks, to protect them from varying interference or to avoid interfering other networks. However, it naturally increases the cost of equipment, thus potentially reducing the benefit of wireless in different environments.

%X Cognitive radio (CR) techniques and cognitive networks [1] aim at optimizing the use of the wireless spectrum, by observing the wireless environment and intelligently configuring radio settings and network parameters. The aim of the FP7 CREW project [2] is to establish an open federated test platform in order to facilitate experimental research on advanced spectrum sensing, CR and cognitive networking strategies. The main goal of this demonstration is to showcase the possibilities of the Belgian branch of the CREW federation. A first aspect is the demonstration of the IBBT w-ilab.t testbed [3] which will be incorporated in the CREW federation, through an example CR set-up where Wi-Fi interference is avoided by an IEEE 802.15.4 network using distributed channel selection. Secondly, a high-performance advanced spectrum sensing design [4] by imec, based on reconfigurable analog and digital building blocks is demonstrated, showing the feasibility of spectrum sensing using low-cost low-power handheld devices. Within the CREW project, the integration of the advanced spectrum sensing component and the testbed (i) generates advanced possibilities for executing and monitoring reproducible testbed experiments, and (ii) allows the optimization of horizontal resource sharing between heterogeneous networks.
