Article
Full-text available
Network management strategies depend on a timely and accurate knowledge of the network performance measures. Among these, one of the most relevant is the delay of the links, which unfortunately is not easy to measure with accuracy, especially when considering multi-hop paths. This is a classical networking problem, for which several solutions have...

Full-text available
Microservices is an emerging paradigm for developing distributed systems. With their widespread adoption, more and more work investigated the relation between microservices and security. Alas, the literature on this subject does not form a well-defined corpus : it is spread over many venues and composed of contributions mainly addressing specific s...

CFP - We would like to invite you to contribute an original paper—either a comprehensive literature review or a full research article—to the special issue on Microservices and Security of the Journal of Cybersecurity and Privacy (MDPI). https://www.mdpi.com/journal/jcp/special_issues/Microservices_Security For submission: http://susy.mdpi.com/use...
Article
Full-text available
Passwords should be easy to remember, yet expiration policies mandate their frequent change. Caught in the crossfire between these conflicting requirements, users often adopt creative methods to perform slight variations over time. While easily fooling the most basic checks for similarity, these schemes lead to a substantial decrease in actual secu...
Article
In this manuscript we present an original implementation of network management functions in the context of Software Defined Networking. We demonstrate a full integration of an artificial intelligence driven management, an SDN control plane, and a programmable data plane. Constraint Programming is used to implement a management operating system that...

Article
Full-text available
New media and devices are offering huge possibilities for the enhancement and the enrichment of heritage experiences, improving the users’ involvement. In particular, tourists equipped with their mobile devices are invading cultural attractions, sharing pictures and comments (together with hashtags and geo-localized positions) on social networks. T...
Article
Full-text available
Mobility is a crucial sector for the livability of urban spaces, both in terms of accessibility for people with disabilities, and in terms of enjoyability by people with different interests. The deep transformation mobility is undergoing, heading towards commoditization of the full spectrum of transportation services, can lead to efficient solution...
Article
Full-text available
Mobility-as-a-Service (MaaS) applies the everything-as-a-service paradigm of Cloud Computing to transportation: a MaaS provider offers to its users the dynamic composition of solutions of different travel agencies into a single, consistent interface. Traditionally, transits and data on mobility belong to a scattered plethora of operators. Thus, we...

Conference Paper
Full-text available
Applications supporting the independent living of people with disabilities are usually built in a monolithic fashion for a specific purpose. On the other hand, a crucial sector for the livability of urban spaces such as mobility is undergoing a deep transformation, heading towards flexible composition of standardized services. This paper shows how...
Conference Paper
Crowdsensing is a powerful approach to collab-oratively build representations of specific aspects of reality which are of great interest for people with special needs. In this paper, we present an evolution of the classical, vertical approach to detect urban barriers and other features to later exploit this knowledge in accessible route planning. B...

The technological compound known as Internet of Things is enabling massive transformations in many fields. In this paper, we deal with one emerging scenario, Mobility as a Service, where the interplay between technical, regulatory and social aspects is intense. We advocate the need for interdisciplinary research, taking into account the different f...

Crowdsensing is a powerful approach to build representations of specific aspects of reality which are of interest for citizens in smart cities, and in particular for people with special needs. In this work, we present an application of the microservice paradigm to create a mobility services platform. By exposing each part of the process as a micros...
Conference Paper
Mobility as a Service takes the concept of XaaS to transportation: a MaaS provider shall merge transport options from different mobility providers, seamlessly handling the whole experience of traveling, from providing information, to travel planning, and payments handling. To effectively support the creation of a market of MaaS providers, we envisi...
Article
Full-text available
This work presents an architecture to help designing and deploying smart mobility applications. The proposed solution builds on the experience already matured by the authors in different fields: crowdsourcing and sensing done by users to gather data related to urban barriers and facilities, computation of personalized paths for users with special n...

The SMAll architecture revolves around the concept of service. SMAll is not simply a collection of services and it is rather an enabler for their deployment. The aim of this class of services is to standardize the data and the interfaces of legacy software to make them available to other services. Other, more complex services, found in the upper layers, orchestrate these basic ones to implement their behaviors, up to the very refined policies of MaaS operators and similar applications.
