  • 1. DEUS Deployment and Ease Use of wireless Services Deus: Design and Easy Use of wireless Services Main challenges In order to ensure the creation of real added value through wireless services, the DEUS project implements a multi disciplinary design process involving both user study groups and technology developers. Three potential application areas are studied in the project: Cultural events: Support of multiple events taking place at the same location, while settings may change from day-to-day. Location-aware and profile-based services in a dynamic wireless environment, such as: virtual museum (story and information based on location and profile of visitor) and tracking/guiding of persons. Guiding of persons in and around public areas: Cheap indoor wireless technology and applications for indoor guiding of persons in public areas (in combination with outdoor guiding based on GPS). Senior mobility support: Tracking and identification of persons (e.g. follow up of people with dementia); Portable device with emergency button and voice connectivity (identical low cost solution in and outside the house). To collect data and information, sensors are deployed in the DEUS solutions. These sensors can collect massive amount of data (such as information on location, temperature, movement etc) in a minimum of time. The challenge is to collect all these data in an efficient way and to combine it with other data from other resources (such as personal profile information). Fast and effective mechanisms in order to turn all these data into the appropriate actions for real service delivery are a major challenge. Intelligent software based on reasoning and subsequent notification actions and interfacing tasks are studied and developed in the project. The developed general software mechanisms result in solutions that are adaptive to new needs and situations.
  • 2. DEUS Deployment and Ease Use of wireless Services Several wireless building blocks (hardware and software) have been studied within the DEUS project. Both wireless sensor networks (ZigBee) and mesh (WLAN) networks have been envisaged. In order to design solutions with real market potential, “plug and play” methodologies for service and network deployment and management are essential. The DEUS solutions enable the service delivery in an intuitive user friendly way. To evaluate these concepts real life PoC (proof of concept) test platforms are developed for user tests and feedback. Deus approach The goal of this project is to make large progress in several wireless fields and related services, with a strong emphasis on ease of deployment and ease of use. The included fields are Wireless Sensor Networks (WSN), WSN-based Indoor Positioning, Wireless Mesh Networks (WMN) and Services which take advantage of these wireless technologies. We have divided this work accordingly in different work packages, each of them addressing specific aspects of the project. Network architecture: Current infrastructures in buildings and public areas are predominantly based on wired network technologies. Although wired infrastructures have proven to be very reliable, once they have been properly installed, wired solutions are not desired in dynamic environments, where the setting may change from day-to-day. These dynamic environments demand for a specific approach. Where wired networks can survive with a onetime install and a minimum of management, constantly changing networks could be an administrative nightmare. DEUS will prove the opposite by providing a easy configurable, self healing and easy manageable, flexible wireless network. Wireless Network architecture: One of the major research areas in the DEUS project is the development of new solutions for wireless sensor networks. Current state of the art solutions fail to meet all the objectives as stated in the DEUS project proposal. They are mostly optimized for a specific USE-CASE or are not able to meet QoS (Quality of Service) – requirements for any given service. Another major shortcoming is the lack of support for different device capabilities.
  • 3. DEUS Deployment and Ease Use of wireless Services The main challenge in the DEUS project is to include all advantages of previous developed architectures without including the drawbacks. This means that our focus lies on supporting heterogeneity and flexibility at any level. We want to support all kinds of devices. Therefore our solution has to work both on always powered high capable devices as on energy harvesting low capable devices. Propagation Prediction Tool: The characterization of path loss in indoor environments has been the subject of extensive research and many models have been proposed to make accurate predictions. The WHIPP (WiCa Heuristic Indoor Propagation Prediction) tool is developed for predicting the wireless coverage for a given set of access points on a certain floor level of a building, based on the building’s geometry and the used materials. The tool also allows to automatically position wireless access points in order to meet a given coverage requirement in the different rooms of the building. Wireless Mesh Networking: Wireless network are omnipresent in modern society, providing ubiquitous computing for everyone. Enterprises and communities wishing to provide these services typically lack the necessary expertise to deploy such networks. As a consequence, they are confronted with two main challenges. The first challenge is to deploy a wireless enterprise grade network. The second challenge is to maintain the network after deployment in order to cope with changing demands and requirements. Pervasive reasoning Platform for WSMN: Deus targets a service platform capable of dealing with geographically dispersed systems connected through a Wireless Sensor and Mesh Network. The platform uses a variety of devices and delivers services that cross device, platform and system administration boundaries. Efficient handling and quality-aware processing of the enormous amount of data coming from a wireless sensor network (WSN) is extremely difficult: data samples are often lost during transmission, many irregular and faulty measurements are produced, and sensor nodes are frequently unavailable. Given the unpredictable and unreliable nature of WSNs, the application must specify and enforce quality requirements: (1) the maximum period between consecutive samples, (2) the minimum coverage (#samples/#available nodes) per room, or (3) the maximum deviation from previous samples from the same sensor.
  • 4. DEUS Deployment and Ease Use of wireless Services Positioning: Knowledge of the current location of an object or moving person is very useful for several applications. In the use cases of DEUS, we want to guide a person through an exposition in a museum or in a historical building. The person receives some sort of PDA when he arrives at the museum, which then provides him with information based on his current location (e.g. information on a specific painting, historical background of a room). It could also guide someone to a specific part of the exposition, based on the interests of the user. The main challenge in DEUS is to provide an easy-to-use and easy-to-deploy indoor positioning solution which achieves room-level accuracy based on cheap, off-the- shelf wireless sensor nodes. User experience: A user-centred design philosophy was followed throughout the DEUS research project. This included several methods for designing, developing and evaluating user-friendly ICT- applications. The first step in this process was to research the generic user requirements for the different application domains. Therefore a user and task analysis was conducted. In a second phase, a conceptual model was developed. This was a translation of the user and task analysis into a specific design and corresponding information structure. In the third phase, storyboards and paper prototypes were developed and tested with end users in order to get feedback on the DEUS solutions’ concepts and user interfaces that were made. Proof-of-concept realization and use cases The results of the different work packages are combined in a Proof of Concept test and 2 use cases. Proof of concept testing: A White book describes the requirements of a generic test platform for the Proof-of- Concept demonstrations. A number of integration sessions are organised to build up the generic test platform, to test the integration of the different work packages and to test the performance issues. This test platform enables the emulation of different possible use cases of the developed technology, within a controlled environment (at the IBBT iLab-t testlab).
  • 5. DEUS Deployment and Ease Use of wireless Services Supporting senior Mobility: The specific use case studied by the DEUS project is the one of tracking and tracing of people based on location and identification of individuals, combined with an emergency call button. Although several solutions exist for partial support (GPS trackers on mobile phones for outdoor use, Personal Alarm Systems for indoor use), DEUS studied an integrated solution for the support of the senior who wants to stay mobile (in- and out- door) but needs augmented attention and follow-up. Guided tour in Arts Centre Vooruit: Arts Centre Vooruit is located in an historical complex monument with more than 300 different areas; in season, over 2000 activities are organised, spread throughout the entire building. Amongst these activities are a great deal of guided tours throughout the monument, and also a number of festivals which show different installations or performances in different areas spread all over the building. Because of security reasons and distribution of information, conducted tours are only possible in group, accompanied by a guide. The DEUS project provides a different solution: at the counter in the entrance hall, each visitor is provided with a wireless device. This will guide the visitor through the monument, and will, in several places, show text, pictures and film clips about the past. Since the device always knows its location within the building, the visitor can never get lost and location-based information can be provided where necessary.
