Article
Runtime monitoring tools have become fundamental to assess the correct operation of complex systems and applications. Unfortunately, the more precise is the monitoring (sampling rate, information granularity, and so on), the higher is the overhead introduced in the system itself. In this paper, we propose a new load shedding framework that enables...
Article
Virtualization allows simultaneous execution of multi-tenant workloads on the same platform, either a server or an embedded system. Unfortunately, it is non-trivial to attribute hardware events to multiple virtual tenants, as some system's metrics relate to the whole system (e.g., RAPL energy counters). Virtualized environments have then a rather i...
Article
In the last few years, multi-core processors entered into the domain of embedded systems: this, together with virtualization techniques, allows multiple applications to easily run on the same System-on-Chip (SoC). As power consumption remains one of the most impacting costs on any digital system, several approaches have been explored in literature...

Multi-tenant virtualized infrastructures allow cloud providers to minimize costs through workload consolidation. One of the largest costs is power consumption, which is challenging to understand in heterogeneous environments. We propose a power modeling methodology that tackles this complexity using a divide-and-conquer approach. Our results outper...
Article
Autonomicity is a golden feature when dealing with a high level of complexity. This complexity can be tackled partitioning huge systems in small autonomous modules, i.e., agents. Each agent then needs to be capable of extracting knowledge from its environment and to learn from it, in order to fulfill its goals: this could not be achieved without pr...
Conference Paper
Internet of Things (IoT) is experiencing a huge hype these days, thanks to the increasing capabilities of embedded devices that enable their adoption in new fields of application (e.g. Wireless Sensor Networks, Connected Cars, Health Care, etc.). On the one hand, this is leading to an increasing adoption of multi-tenancy solutions for Cloud and Fog...
Conference Paper
In the last decade we have witnessed the birth and dramatic growth of mobile devices, from cellular- to smart- phones. Despite the huge amount of information achievable from an always-connected reality, researchers that work in the mobile devices field fight against the impossibility to explore, inspect and test their work on such a vast set of pos...
Conference Paper
Full-text available
Resources such as quantities of transistors and memory, the level of integration and the speed of components have increased dramatically over the years. Even though the technologies have improved, we continue to apply outdated approaches to our use of these resources. Key computer science abstractions have not changed since the 1960’s. Therefore th...

In the context of mobile devices, the thermal prob- lem is an emerging one, as it affects the user experience and involves factors that are both internal and external with respect to the device. In this paper, we present an evaluation of these factors, that consists of two parts. The first one is the analysis of thermal interactions between the int...
Article
In nowadays life, mobile phones are becoming a cheaper and smaller alternative to laptops for simple, everyday tasks. They experienced an astonishing growth in functionalities and, because of their constant presence in our life, mobile phones became fundamental for the interaction with information coming from the environment. Nevertheless, their re...
Conference Paper

Mobile devices take an important part in everyday life. They are now cheaper and widespread, but still a lot of time is spent by the users to configure them: users adapt to their own device, not vice versa. Can our smartphones do something smarter? In this work, we propose a framework to support the development of context aware applications for And...
Article
Full-text available
Mobile devices have become the main interaction mean between users and the surrounding environment. An indirect measure of this trend is the increasing amount of security threats against mobile devices, which in turn created a demand for protection tools. Protection tools, unfortunately, add an additional burden for the smartphone's battery power,...
Conference Paper
Full-text available
Nowadays, mobile devices are becoming more flexible and rich in functionalities. As already presented in [6] those devices are highly influenced by constraints, mainly regarding power management. In fact, mobile batteries are limited in time and there are no efficient methods able to manage power consumption. Even knowing the device Time To Live (T...
Conference Paper
Full-text available
Due to their wide distribution and their growth in functionalities, mobile devices are the interaction point between users and the surrounding environment. Nevertheless, their resources are limited and variable over time, both in terms of performance and power. Especially when dealing with power consumption, mobile devices cannot disregard the envi...
