Wireless visionaries for 2020

The WiVi-2020 project (H2020 MSCA-ITN, project no. 642743) brought together an academic/industrial consortium with complementary skills and views to address three objectives, as defined by joint discussions, considering mainly the needs, interests and activities of the involved industrial partners of WiVi-2020: (a) take advantage of the coexistence of different radio technologies via flexibility on the usage of spectrum and traffic over multiple radio devices, (b) investigate architectures and planning for optimized indoor heterogeneous radio access of software defined networks that support services with different QoS requirements, and (c) optimize resources scheduling and traffic flows for virtualized networks based on SDNs. To address these, WiVi-2020 engaged in a four-year research program centered on six industrial-oriented PhD projects, with each of the objectives above targeted by pair of Early-Stage Researchers under inter-sectoral guidance and supervision.

Smart Objects for Intelligent Building Management

SOrBet was a 48 month Marie Curie Industry-Academia Partnerships and Pathways (IAPP) project, which was funded by the European Union under Call FP7-PEOPLE-2013-IAPP in FP7 (project no. 612361). It aimed towards highly distributed, self-organizing, self-managing, wirelessly communicating Smart-Objects, enabling the robust management of energy efficient Smart Buildings. In doing so, drawbacks of current systems were used as starting points in developing a framework based on the concept of “reliability by design”. Drawing lessons from the Internet of Things (IoT) worked towards realizing the concept of “reliability” in intelligent buildings and mitigating the issues mentioned above. In addition to R&D, SOrBet contributed to competitiveness development in the European Research Area (ERA) by training researchers. A strong knowledge transfer program was designed on a mutual-benefit basis between the academics and industrial partner, to promote new career opportunities and development in the European Information and Communication technologies (ICT) arena, and thereby generated new types of expertise and human capital for ERA.

Self-organising MESH Networking with Heterogeneous Wireless Access

The MESH-WISE project (FP7, project no. 324515) mobilized a joint academic-industry task force on two complementary themes. First was the development of novel mechanisms for deployment and resource allocation of self-organising mesh networks. The second theme comprised the investigation of multipurpose and heterogeneous mesh networking and its emerging applications such as traffic offloading, emergency deployment and provisioning, and sensor integration. Designing future wireless mesh systems based on heterogeneous radio technologies with self-organizing capabilities necessitates original R&D actions. The MESH-WISE project took a holistic view in developing models, protocols, and algorithms in a wide spectrum, from theoretical analysis to proof-of-concept and prototyping. Towards these ends, the project followed the approach of intensive inter-sectoral exchange of knowledge and know-how between the consortium partners. In addition to R&D, MESH-WISE contributed to competitiveness development by training researchers. The knowledge transfer program was designed on a mutual-benefit basis between the academic and industrial partners, to promote new career opportunities and development in the European Information and Communication technologies (ICT) arena, and thereby generate new types of expertise and human capital for the European Research Area (ERA).

Reliable, resilient and secure IoT for smart city applications

The main goal of the project (FP7, project no. 609094) was to enhance the trustworthiness of IoT technologies by designing an IoT architecture that adopted the concepts of “security, privacy and reliability by design”. The functional architecture of RERUM was based on the Architectural Reference Model (ARM) of IoT-A. However, RERUM followed not only a service-oriented approach like IoT-A and most IERC projects, but assumed that the Devices play a very important role into ensuring the security and the privacy of the architecture. Thus, RERUM followed also a device-oriented approach, implementing many Security, Privacy and Trust, as well as networking functional components on the IoT devices. RERUM includeed components for integrity generation/verification, data encryption, policy handling mechanisms (PDP, PEP and PRP), as well as secure storage of data and credentials. Key innovations within the project were the mechanisms for device-to-device authentication (allowing the distributed authentication between devices, without the need for centralised control) and the secure credential bootstrapping, so that whenever there was a need for changing/assigning credentials to devices, this was performed using a secure channel.

OPerational Trustworthiness Enabling Technologies

The OPTET project (FP7, project no. 317631) planned through a multi-disciplinary and integrated approach to identify and address the drivers of trust and confidence also fight against its erosion (especially true on the Internet or Cloud). Focus of this project was on socio-technical systems connected to the Internet. The resulting technologies enabling trustworthiness were verified on two distinct existing execution platforms to demonstrate genericity of OPTET outcomes. Potential of OPTET results were demonstrated and evaluated in the context of two operational use cases one in the domain of Ambient Assisted Living (AAL) and second Cyber Crisis Management. Overall, the OPTET project significantly increased the trustworthiness of IT and Services and thus strengthened the competitiveness of the European software and service industry. In doing so OPTET provided a powerful foundation for designing and developing trustworthy system/services/apps stakeholders can trust (since provable also guaranteed) for the future internet realizing its promises.

Rapid Emergency Deployment Mobile Communication Infrastructure

The REDComm project (project no. HOME/2011/CIPS/AG/2107) built a mobile infrastructure able to handle emergency communications, without the need of standard telecom networks. Its architecture is based on: a command center for coordinating the emergency responders, and several mobile units that communicate with the command center. The mobile units form a backbone wireless mesh network able to cover a large area providing an independent network for ubiquitous heterogeneous services (i.e. WiFi, GSM). In this respect, the citizens are able to dial emergency numbers (i.e. 112) and communicate with the command center to seek or provide help. Moreover, the command center is equipped with a variety of radio equipment employed by the police / fire departments and other emergency response teams. In that way, it provides the needed infrastructure for emergency communication in crises.

Autonomous Control of Large-scale Water Treatment Plants based on Self-Organized Wireless BioMEM Sensor and Actuator Networks

The HYDROBIONETS project (FP7 ICT-1-1.1: The Network of the Future, project no. 215320) focused on the research and development of Self-Organized Wireless BioMEM Networks (WBNs) and their integration in a global system to monitor the complete water cycle in large-scale water treatment and desalination plants. The key feature was the integration of BioMEM sensors and actuators in motes and the adaptation of the network function to the specific requirements that this type of application imposed. The WBNs achieved a distributed monitoring of critical parameters, representing a novel instrument that could be successfully applied in a short term to the great challenge that represents the dense wireless networked control of microbiological parameters of water in the different stages of process in these plants.

EU-MESH: Enhanced, Ubiquitous, and Dependable Broadband Access using MESH Networks

EU-MESH's goal was to develop, evaluate, and trial a system of software modules for building dependable multi-radio multi-channel mesh networks with QoS support that provided ubiquitous and ultra-high speed broadband access. The system was based on a converged infrastructure that used a wireless mesh network to aggregate the capacity from both subscriber broadband access lines and provider fixed broadband links to form a virtual capacity pool, and provided access to this capacity pool for both stationary and mobile users.
