What is the eWINE Grand Challenge?
The eWINE Grand Challenge addresses problems that deal with elastic connectivity. It targets the research community and highly trained industry professionals that want to optimize network solutions through autonomous control algorithms rather than manual configuration of devices. Competitors are requested to demonstrate PHY, MAC, routing or localization solutions that can scale to a high number of users in a short timespan through the use of an agile infrastructure (intelligent software and flexible hardware). Competitors are allowed to design their own intelligence solutions, but can also build on the top of accessing facilities and software tools developed in two H2020 projects: CREW and WiSHFUL.

5G Flexible Transceiver for Physical Layer Evaluation - 5GFlexPHY
Title: 5G Flexible Transceiver for Physical Layer Evaluation – 5GFlexPHY
Contact person: Luciano Leonel Mendes
Affiliation: Instituto Nacional de Telecomunicações – Inatel, Brazil
Summary: 5G is being widely researched nowadays. Several waveforms show features to be employed in 5G
networks. However, performance analyses are based on theoretical or simulation results, with
simplified channel model. Non-linearities, phase noise, interferences and other impairments present
in a wireless channel are usually neglected. The eWINE flexible PHY component allows a first realtime
study, however only for SISO transceivers. The aim of this proposal is to extend the eWINE
infrastructure with MIMO capabilities to improve and evaluate the performance of the flexible PHY
system under real channel conditions. The MIMO processing blocks will be developed for the XILINX
Kintex 7 FPGA inside the USRP software-defined radio platform.

Enabling Agile Adaptation in Dense Heterogeneous Deployments of Commercial 802.11 Devices
Title: Enabling Agile Adaptation in Dense Heterogeneous Deployments of Commercial 802.11 Devices
Contact person: Efstratios Kerandis
Affiliation: GRIDNET S.A., Greece
Summary: In this demonstration, we will present the AGILE system providing for rapid deployment on top of
COTS 802.11 hardware to address elastic Wi-Fi connectivity issues. The key novelty of AGILE lies in
the adoption of an efficient cross-layer approach, combining the detail of information available at
low networking layers with the ability of implementing sophisticated algorithms at the application
layer. We will showcase three individual scenarios highlighting the advantages of applying
autonomous mechanisms to provide distributed spectrum adaptation, low-quality link mitigation and
centrally controlled traffic load distribution. The experiments will be deployed in NITOS testbed
featuring compatible 802.11ac hardware.
Intelligent Network Control for the Internet of Things INTER-IOT
Title: Intelligent Network Control for the Internet of Things INTER-IOT
Contact person: Lefteris Mamatas

Summary: The CORAL framework expands the Software-Defined Networks (SDNs) concept to the Internet of Things (IoT). This integration enables efficient end-to-end wireless communication based on dynamically optimized routing for heterogeneous mobility-aware networks. CORAL brings elastic network adaptations, such as SDN-based network discovery, topology maintenance and routing, over IoT devices to improve performance, reduce cost and resource utilization; a novel visualization platform based on Node-RED is used for illustration. Exploiting the WiSHFUL and eWINE infrastructures is double beneficial for our framework: CORAL is based on a real test-bed with innovative facilities, whilst it is enhanced with intelligence to support our controller decisions.

Network Access: Smart Detection And QoE-based selection - NASDAQ
Title: Network Access: Smart Detection And QoE-based selection – NASDAQ
Contact person: Maria-Gabriella Di Benedetto
Affiliation: Sapienza University of Rome, Italy
Summary: In the context of heterogeneous and coexisting networks, the introduction of context-aware and
cognitive mechanisms may allow the final user to optimize 1) the detection of surrounding access
networks, and 2) the selection of the best one, thus improving Quality of Experience (QoE). The
present proposal investigates this approach, by introducing the use of 1) MAC layer parameters for
the detection of surrounding networks, and 2) application layer QoE parameters, namely Key
Performance Indicators (KPIs), for optimizing the access network selection, respectively. MAC
parameters and KPIs will be defined for different traffic types, and then used to 1) detect and
recognize the access networks in the user surrounding area, 2) rank them, and select the one with
highest estimated QoE, for each considered traffic type.

Indoor Positioning by UWB Fingerprinting I-PUF
Title: Indoor Positioning by UWB Fingerprinting I-PUF
Contact person: Maria-Gabriella Di Benedetto
Affiliation: Sapienza University of Rome, Italy
Summary: This proposal explores the application of the fingerprinting approach to UWB positioning systems.
The system will use location-dependent UWB signal propagation features collected in specific points
of the area of interest, for obtaining an estimate of the position of the target node by comparing
offline data with online readings, via pattern matching and machine learning techniques. Locationdependent
features of the UWB Channel Impulse Response will be identified, that enhance
positioning accuracy of traditional ToA/TDoA ranging-based schemes in harsh indoor scenarios,
affected by non Line of Sight (NLoS) and imperfect time synchronization conditions between the
anchor nodes and the target node.

Design and Prototype of a Multi-Objective Environment Sensing Capability System for Shared Access With Rotating Radars
Title: Design and Prototype of a Multi-Objective Environment Sensing Capability System for Shared Access With Rotating Radars
Contact person: Zaheer Khan
Affiliation: University of Oulu, Finland and University of Liverpool, UK
Summary: Recent recommendations by regulatory bodies to use a distributed network of spectrum sensing/measurement devices, called environmental sensing capability (ESC) devices, which facilitates shared access (SA) between wireless communications and rotating radar systems has generated considerable research interest. We demonstrate a prototype of a multi-objective ESC system that facilitates a spectrum access system (SAS) to enable SA with ground-based fixed rotating radars. The implemented ESC device 1) detects radar signals; 2) measures interference from secondary users (Sus) for radar protection; and 3) also measures SUs’ airtime utilization (ATU) in a channel. The proposed ESC assisted SAS architecture can help in reducing the size of currently proposed large exclusion zones around the rotating radar systems. The prototype of the proposed ESC is implemented on Wireless Open Access Research Platform (WARP) nodes with Xilinx Field-programmable gate array (FPGAs).

Contact person: Zaheer Khan
Affiliation: University of Oulu, Finland and University of Liverpool, UK
Summary: To provide more frequency spectrum for smart wireless devices and new things in the IoT, there is an increasing research interest in systems that facilitate spectrum sharing between radars and wireless communications. We will demonstrate real implementation of a database assisted shared access (SA) system for rotating radars and wireless communications. Our implemented SA system includes: 1) a real-time rotating radar emulator which has been designed to generate real scanning patterns of three different rotating radar systems; 2) a real-time MySQL database which assigns rules for SA-based spectrum access; and 3) A real-time FPGA-based prototype of wireless users using frequency spectrum on SA-basis. The prototype is implemented on WARP (a scalable and extensible programmable wireless platform) nodes .
