  4. Vision (1) • The Network of Excellence CRUISE(CReating Ubiquitous Intelligent Sensing Environments - FP6-IST-4-027738-NoE) intends to be a focal point in the planning and coordination of research on communication and application aspects of WSNs in Europe. • CRUISE aims at building an effective team based upon a pool of academic and independent R&D organizations, that each are excellent in in the field of WSNs, with the goal of : • effectively serving European society and industry, • putting the European WSN research community and industry in the position to successfully compete with the US. 12th MCM COST289 - Florence, October 30th – 31st, 2006

  5. Vision (2) • CRUISE consortium can achieve these objectives though: • Creation of a state-of-the-art Knowledge Base, available to the general public • Information collection, comparison, validation and dissemination • Solution of specific theoretical and technological problems • Establishment of a framework of common tools and methodologies to accelerate the research process and build sustainable collaboration links • Teaching and training, and novel techniques for knowledge management collaboration and dissemination (e-learning@CRUISE) • Collaboration with industry and European research initiatives active in this field • Stimulation of open discussion on the issues of standardization, international collaboration, and intellectual property • The CRUISE consortium will identify short-term and long-term benefit, beyond the 24-month period of project funding 12th MCM COST289 - Florence, October 30th – 31st, 2006

  6. Technical context (1) • The NoE CRUISE focuses on the communication and application aspects of WSNs, including all related and supportive technologies. • The field of WSN research has been attracting tremendous interest particularly since technological advancements make the matching of their requirements just a matter of time. • The potential for innovative user-centric applications is one of the most exciting aspects of WSNs, which creates a high motivation for working on the variety of challenging research topics. • At present WSNs are driven by two partially opposing trends: • Using the open software, or firmware, which can be freely customized in the application-specific way, • Standardizing general protocols. 12th MCM COST289 - Florence, October 30th – 31st, 2006

  7. Technical context (2) • CRUISE propose an alternative way by promoting discussion and strengthening research cooperation between industry and academia, within and beyond the boundaries of the consortium, while maintaining an academic nature. • CRUISE intends to act as a catalyst for the creation of an habitat for WSN community in Europe, yielding: • Close co-operation with industrially oriented fora and with other existing NoEs and Integrated Projects (IPs) • Long-term research and education co-operation between leading European universities and research institutes, beyond the initially funded period. • The CRUISE consortium is committed to serving the European research community, industry, and citizenship. 12th MCM COST289 - Florence, October 30th – 31st, 2006
