Here we present the overall objectives and approach of the SAPERE (" Self-aware Pervasive Service Ecosystems ") project, focussed on the development of a highly-innovative nature-inspired framework, suited for the decentralized deployment, execution, and management, of self-aware and adaptive pervasive services in future network scenarios. © Selection and peer-review under responsibility of FET11 conference organizers and published by Elsevier B.V. 1. Motivations Pervasive computing technologies promise to notably change the future ICT landscape, letting us envision the emergence of an integrated and very dense socio-technical infrastructure for the provisioning of innovative general-purpose digital services. The infrastructure will be used to ubiquitously access services for better interacting with the surrounding physical world and with the social activities occurring in it. It is also expected that users will be able to deploy customized services, making the overall infrastructure as open as the Web currently is. To support the vision, a great deal of research activity in pervasive computing and service systems has been devoted to solve problems such as: increasing dependability; supporting self-* features; enforcing context-awareness and adaptability; tolerating evolution over time and eventually ensuring that service frameworks can be highly-adaptive and very long-lasting . Unfortunately, most of the solutions so far are proposed in terms of " add-ons " to be integrated in existing frameworks. The result is often an increased complexity of current frameworks and the emergence of contrasting trade-off between different solutions. In our opinion, there is need for tackling the problem at the foundation, answering the following ambitious question: is it possible to conceive a radically new way of modeling integrated pervasive services and their execution environments, such that the apparently diverse issues of context-awareness, dependability, openness, flexible and robust evolution, can all be uniformly addressed once and for all? 1877-0509/$ – see front matter © Selection and peer-review under responsibility of FET11 conference organizers and published by Elsevier B.V.
