Eviot

Over the last decade the number of devices connected to the Internet has grown exponentially and applications running on platforms using these devices are constantly evolving as user needs change. These phenomena impose stringent requirements on network and computing infrastructures to support Internet of Things (IoT) platforms, one of the most important of which is the ability to flexibly adapt to the needs of dissimilar and constantly evolving application scenarios. Therefore, there is a need for platforms that are “evolutionary-by-design”, which connect objects with cognitive capacity, so that their behavior adapts over time on the basis of the context in which they are located, in interaction with other objects, Internet services, the environment, the network, and the users who use them. Objects should therefore be able to detect and analyse the state of the outside world (through cooperation with other objects), process the data obtained, and update their knowledge of the context. Moreover, the platform can be defined as evolutionary thanks to the following features: Cooperativity between objects, allowing the execution of distributed applications that access the functionality of objects belonging to systems with different owners. In this way, new implementations can be performed without significant installations of additional physical devices and thus avoiding duplication of physical devices with the same or similar functionality; Interoperability, which entails the adoption of standard interfaces and semantic tools that allow data exchange between platforms in different administrative domains while fulfilling data ownership rights; The exploitation of smart grids, necessary to provide physical devices with the necessary processing and storage capacities in a flexible way, depending on their geographical location; The development of customised services through Quality of Experience (QoE) assessment, which decides on the success of applications. Based on these considerations, the project focuses on the definition and development of functionalities for an evolutionary IoT platform, which is able to better adapt to evolving needs and contexts. In particular, the project will allow the introduction of a set of open and standard APIs (Application Programming Interfaces) to foster interoperability between platforms, together with a set of rules and logic needed to stimulate the development of cognitive objects to support cooperation between systems managed by different administrations. The development of methodologies to monitor the quality of the experience lived by users, to continuously assess the value perceived by the user and to adapt applications with the aim of increasing their chances of success. The methodologies will be based on the definition of non-invasive but effective metrics for monitoring and at the same time able to guide the evolution of platforms and applications based on perception models.
