BUTLER’s concept is to develop a natively secure, pervasive, energy-efficient and optimized context-aware opened architecture, by bundling and integrating IoT technologies and services to transparently learn and infer the behaviours and needs of users, acting on their behalf of and protecting them so as to improve their quality-of-life.
BUTLER aims to design and demonstrate the first prototype of a comprehensive, pervasive and effective Context-Aware information system, which will operate transparently and seamlessly across various scenarios towards a unified smart urban environment.
BUTLER will focus on five different vertical domains: Smart Transport, Smart Health, Smart Shopping, Smart Home and Smart City.
3 challenges are addressed by the BUTLER project:
- - CHALLENGE 1: Personalized and Dynamic Demands: How to handle large and dynamically varying demands for personalized services, goods and information with vast heterogeneity of context?
- - CHALLENGE 2: Transparency, Privacy and Security in Heterogeneous Systems: how to maintaining transparency to end-users while ensuring the privacy of users and security of information in such heterogeneous environments, which in turn calls for universal mechanisms to provide secrecy over communication channels at lower layers such as the network and physical layers?
- - CHALLENGE 3: Collective Behaviour Modelling to Maximize Efficiency: How to optimize the impact that ICT systems have in influencing human behaviour towards best practices?
