Air pollution is an important issue due to its direct impact on human health. To cope with this problem, in urban areas a “monitor and react” approach, based on measurements provided use of static monitoring stations, is commonly adopted introducing constrains to the amount of areas that can be monitored within the city. With the rise of the Internet of Things paradigm, new air monitoring models based...
Today more, more Web services are exposed to developers through public APIs (API-fication), enabling the spread of new services which create value for end users. The number of these services is expected to grow in the coming years. This will complicate the user experience due to the complexity required to figure out which of the available services are the most relevant and, also, the need for a user...
Some support is needed in order to shun the possibility that sensitive data handled by applications are sent to improper destinations. Although apps running on Android OS declare the accessed services, once the user accepts, the application receives complete permissions and may use sensitive data improperly. Some tools have emerged to check data access and flow, however such tools are either based...
The emergent wireless Network-on-Chip (WiNoC) design paradigm has been proposed as a viable solution for addressing the scalability issues affecting the on-chip communication system in future manycores architectures. Within this scenario, the energy contribution of the buffers (both of the routers and radio-hubs) and the transceivers of the radio-hubs, account for a significant fraction of the total...
Finding a parking slot is a process very stressful for a person who would like to reach a specific place. It could be considered also expensive since it often causes an increasing of traffic with a consequent increase of pollution. In this paper, we present a smart parking system that helps users to reach a free parking slot, in a small area or a city, using context-aware information to help in the...
The wireless Network-on-Chip (WiNoC) design paradigm represents an emergent and viable solution for addressing the scalability limitations of future manycores architectures. Unfortunately, components such as the buffers and the transceiver of the radio-hubs in a WiNoC, account for a significant fraction of the total communication energy budget. In this paper, we present WIRXSleep, a mechanism aimed...
The rapid evolution of mobile computing, together with the spread of social networks is increasingly moving the role of users from simple information and services consumers to actual producers. Currently, while most of the critical aspects related to User-Generated Contents (UGC) have been addressed, many issues related to service generation still must be faced and represent the next challenge. In...
Emerging on-chip communication technologies like wireless Networks-on-Chip (WiNoCs) have been proposed as candidate solutions for addressing the scalability limitations of conventional multi-hop NoC architectures. In a WiNoC, a subset of network nodes are equipped with a wireless interface which allows them long-range communication in a single hop. This paper presents Noxim, an open, configurable,...
In the last years, a lot of attention has been paid to Internet of Things (IoT): everyday life objects, thanks to the advanced technological features added to them, are becoming “smarter”. Regarding this new and potentially disruptive field, it is important to take into account the primary role that the user has in these ecosystems. IoT applications will be used by different kinds of people, with...
Mobile devices became the main repository of personal data and source of user-generated contents as well as the principal controller of our social networked life. In this scenario, malicious applications try to take advantage of all the possibilities left open by users and operating systems. In this paper, we propose SecureDroid: an extension of the Android security framework able to enforce flexible...
M2M represents a future where billions to trillions of everyday objects and the surrounding environment are connected and managed through a range of devices, communication networks, and cloud-based servers. In particular, the Web of Things (WoT) approach exploits some common standard web technologies to address the problem of access and connectivity of such devices. In this paper the usage of the...
Web browsers are a common platform for delivering cross-platform applications. However, they currently fail to provide consistent access control for security and privacy sensitive JavaScript APIs, such as geolocation and local storage. This problem is exacerbated by new HTML5 APIs and the increasing number of personal devices people own and use. In this paper we present the webinos platform which...
The widespread use of OPC UA specification in client/server data exchange in industrial environment introduces many benefits as it allows to keep open the market of the industrial applications, due to the presence of a standard, worldwide and vendor-independent specification. On the other hand, the use of a software infrastructures (complex in the case of OPC UA) between industrial applications and...
