The availability of interoperability standards allows using a uniform model for integrating technologies and designing collaborating applications with a shared understanding of the exchanged information. In this perspective, we propose here the design and development of an agent-based platform that uses an interoperability framework to build a diffused museum in a cyber-physical system, where inte...Show More
Archaeological research that uncovers ancient artifacts is of critical importance, since ruins and objects are the only way to deal with the history of a city. Artificial intelligence techniques can support the archaeologists to discover remains which are difficult to be identified manually as they must be sought on a vast territory or because they are hidden from direct observation. Here we prese...Show More

Internet of Things and Big Data are characterizing more and more application scenarios and research fields such as Smart Cities, Smart Energies representing information. In fact smart objects represent a kind of producers and consumers of huge amount of heterogeneous data which increase at higher rate. In order to let them play the role of new actors in Cyber Physical Systems it need to enable the...Show More
Cloud computing is probably the simplest and best fitted way for improving scalability and flexibility ofa smart-grid, however, migrating such critical data-intensive applications to the cloud is not a trivial challenge. For such applications, high security, resilience, and performance are non-negotiable. Therefore, in order to successfully host critical smart-grid applications and workloads, new ...Show More
In the last years, the Cloud services market experienced an extremely rapid growth, which may lead to severe scalability problems. Therefore, in order to cope with the resource capacity limits of a single Cloud provider, as well as to address the vendor lock-in problem associated to the choice of a single proprietary Cloud solution, the concept of federating multiple heterogeneous organizations is...Show More
The monitoring of the resources is one among the major challenges that the virtualization brings with it within the Cloud environments. In order to ensure scalability and dependability, the user's applications are often distributed on several computational resources, such as Virtual Machines, storages and so on. For this reason, the customer is able to retrieve information about the Cloud infrastr...Show More
In the last years, the cloud services market has experienced an extremely rapid growth, as reported in several market research reports, which may lead to severe scalability problems. Therefore, federating multiple clouds is enjoying a lot of attention from the academic and commercial point of views. In this context, publish-subscribe is a widely used paradigm to support the interoperability of fed...Show More
Monitoring of resources is one among the major challenges that the virtualization brings with it within the Cloud environment since the user applications are often distributed on several nodes whose location is unknown a priori and can dynamically change. Consumers need to monitor their resources for checking that service levels are continuously compliant with the agreed SLA and for detecting unde...Show More
The business sector is exploring the locations and movements information of mobile users with the purpose to improve the business operations and increase the sales volume. In this scenario, the location systems should be able of tracking the mobile users in any place they move to, both indoor and outdoor scenarios. In this paper, we propose a hybrid location approach designed to support the choice...Show More
This paper investigates agent-based modelling and design of a real time mission planning module for an Unmanned Aerial Vehicle (UAV). Agents can act on behalf of remote human operators, who impose mission objectives, performing autonomous or supervised behaviours. The planning module is in charge to deliberate the strategic tasks to achieve mission objectives and to satisfy environment constraints...Show More

Cloud Computing represents both a technology for using computing infrastructures in a more efficient way, and a business model for selling computing resources and services. On the other hand, such complex and distributed architectures become an attractive target for intruders. Cyber-attacks represent a serious danger, which can compromise the quality of service delivered to the customers. In this ...Show More
In the Cloud context, the monitoring of service levels becomes critical because of the conflicts of interest that might occur between provider and customer in case of outage. Here we focus on Cloud monitoring at infrastructure level (IaaS), but with the perspective of a Cloud customer. Cloud customers cannot check the compliance of the Service Level Agreement (SLA) trusting the monitoring service ...Show More
Many contexts of every-day life are characterized by pervasiveness and ubiquity of embedded systems. These features can be exploited to support people in different scenarios, such as emergency situations and post disaster management. In this paper, we propose an agent-based approach to assist and simulate human critical activities in such scenarios. We propose a rule-based solution, which is imple...Show More
The increasing complexity of services required by users in Cloud Environments usually needs the definition of composite, value added services (VAS). Usage patterns and Use Cases definitions help in defining VAS, but a way to assure that new services reach the required goals with proper qualitative and quantitative properties has to be provided in order to validate design and implementation of comp...Show More
Cloud Computing is a new computing paradigm. Among the incredible number of challenges in this field two of them are considered of great relevance: SLA management and Security management. The level of trust in such context is very hard to define and is strictly related to the problem of management of SLA in cloud applications and providers. In this paper we will try to show how it is possible, usi...Show More
The easiness of managing and configuring resources and the low cost needed for setup and maintaining Cloud services have made Cloud Computing widespread. Several commercial vendors now offer solutions based on Cloud architectures. More and more providers offer new different services every month, following their customers needs. Anyway, it is very hard to find a single provider which offers all ser...Show More
Pervasiveness of electronic devices and networks allows to design ubiquitous services, which use distributed sensors as their extensions. Localization of mobile objects using standard protocols and infrastructures is an open issue. Standard protocols that allow an integrated use of heterogeneous technologies have been defined, but it is necessary to use terminals, which are enabled to exploit a mi...Show More
The cloud paradigm appeared on the computing scene in 2005 with the Amazon Elastic Compute Cloud (EC2). After this date, a large set of related technologies has been developed. In the academic world, and especially in the HPC area, cloud computing is in some way in competition with the GRID model, which offers a middleware based approach. One of the solutions proposed is the integration of the two...Show More
Many application contexts noways are characterized by pervasiveness of embedded systems in crowded environments of everyday life. To accomplish common requirements ubiquitous computing must address many issues such as communication among users, services and sensors, security, interoperability, collection of information and context representation. Here we present a distributed solutions based on au...Show More
According to SOA model (Service Oriented Architecture), services can be used or can use other services. Participation is not supported. A service cannot collaborate with other partners being aware of this collaboration. As Grid services are developed according to the SOA model, we investigate how the integration of mobile agent technology in Grid architectures can help to overcome this limitation....Show More
The resource allocation problem is a classical problem in the scientific literature. Here, authors present an architectural model to allow optimum resource allocation in a grid environment. They are investigating a decentralized approach to address this problem into an inter--grid nodes context; instead they argue in favor of a centralized approach in an intra--grid node context (i.e., a cluster a...Show More
Advanced grid functionalities and applications can be developed exploiting mobile agents technology. State-full migration can help to distribute computation where data reside and among new available and less busy machines. However when mobile agent technology is used new kinds of interaction facilities, such as cloning and migration, require execution of agent platforms, which represent an additio...Show More
