DEWI will provide key solutions for wireless seamless connectivity and interoperability in smart cities and infrastructures, by considering everyday physical environments of citizens in buildings, cars, trains and aeroplanes, thereby significantly contributing to the emerging smart home and smart public space.

DEWI, with its four industrial domains (Aeronautics, Automotive, Rail, Building) will add clear interoperability and cross-domain benefits in the area of wireless sensor networks and wireless communication, in terms of re-usability of technological building bricks and architecture, processes and methods.

Based on more than thirty clear business needs identified by DEWI industrial partners, the concept of the DEWI Bubble is being realized in twenty-one industry-driven use cases, aimed at tackling dependable, auto-configurable, optionally secure, short-range communication, local energy-management (efficiency, harvesting, storage), the localization of sensors and mobile devices, and the smart composability and integration of WSNs. These many and various use cases of DEWI will clearly highlight the ad-vantages of replacing wired by wireless solutions. Some of the benefits are lower weight in weightsensitive environments, more flexibility and re-configurability, easy, cost-effective feature updates, novel “bring your own device” applications, error elimination – caused by faulty wiring – by self-managed wireless networks, the reduction of installation costs by simplified deployment procedures, and easy switching of network topologies. The key results of DEWI will be shown in the attractive real-life demonstrators of the DEWI Bubble.

Furthermore, the project will contribute to emerging international standards, influence new regulations and lay the basis for efficient certification processes. In addition, DEWI will make a significant contribution to and benefit from existing ARTEMIS Tool Platforms, the ARTEMIS Repository and ARTEMIS sub-programs, providing not only concrete input through its well-defined technology items, but also strategic input to other fields of application.

Aeronautics

So far, aeronautics industry has been particularly reluctant to the adoption of wireless networks due to its highly critical operation standards. Therefore the development of the wireless DEWI Bubble for the aeronautics industry is a major challenge. Solutions provided have to comply with the high standards, low interference levels and harsh environmental conditions of the aeronautical industry, and have to enable flexible and competitive applications that foster business and revenue for all stakeholders of the aeronautics industry.

Automotive

In the Automotive Domain, the aforementioned DEWI Bubble typically covers one vehicle, for in-vehicle use in passenger cars as well as for heavy vehicles like trucks and offroad use in excavators. Another important aspect is the application of measurement systems based on WSNs for verification and validation during automotive development, for example in engine test beds or test vehicles.

Rail

So far, wireless technology is not widely used in the rail industry. However, it may provide the base to develop new functionalities, like the Train Integrity Management or to increase pre-existing functionalities like the Train Position Report.

Building

The Building Domain focuses on the development of the DEWI bubble for the building industry, maintenance and management of buildings. The building itself provides the most common ground for wireless technologies of all the domains. Wireless technologies were introduced in buildings since the very first solutions became available. Yet, there is still much room for improvement of the utilisation of wireless technologies in buildings. Especially the management and maintenance operators have only recently started exploiting the Internet of Things (IoT) technologies to improve their systems and services. In this systems and service innovation, wireless technologies such as sensor networks play a key role.

Interoperability

Interoperability is defined as the ability of diverse sensor networks or sensor nodes to exchange information and to make mutual use of the information that has been ex-changed. DEWI follows the official definitions coming from ISO/IEC 29182-2:2013(E) [Information technology – Sensor networks: Sensor Network Reference Architecture (SNRA) – Part 2: Vocabulary and terminology].
