We investigate the consequence of failures, occurring on the electrical grid, on a telecommunication network. We have focused on the Italian electrical transmission network and the backbone of the internet network for research (GARR). Electrical network has been simulated using the DC power flow method; data traffic on GARR by a model of the TCP/IP basic(More)
Modeling and analyzing critical infrastructures and their interdepen-dencies are essential to discovering hidden vulnerabilities and threats. Several current approaches engage a holistic perspective and rely on abstract models; others incorporate a reductionistic perspective and focus on inter-domain and intra-domain interactions among elementary(More)
— This paper investigates the implementation of a wireless mobile ad-hoc network to guarantee that an autonomously driven mobile vehicle remains connected to a limited-coverage base antenna during its motion. To the purpose, the use of a platoon of mobile robots is proposed to carry a number of repeater antennas; these must be suitably moved to dynamically(More)
Performing the requirements engineering process for software-intensive systems, characterized by a high organizational impact, requires the analysts to handle a large amount of information, related to desires, needs, and constraints of a vast number of completely different stakeholders. The paper presents an <i>organization modeling-based requirements(More)
This paper investigates the implementation of a wireless mobile ad-hoc network to guarantee that an autonomous agent, i.e., an autonomously driven mobile vehicle or a human, remains connected to a fixed base station while performing its own mission. To the purpose, the use of a platoon of mobile robots is proposed to carry a number of repeater antennas;(More)
