The main reference of SCNL research activity has been and is Quality of Service (QoS) management over heterogeneous networks, including satellite and wireless network portions, and network and critical infrastructure security issues. The main research topics currently addressed by the SCNL Lab are:
Satellite Communication Networks
Satellite Communication (SatCom) networks have always had a main role in allowing communicate people located in areas not covered by other communication technologies. However, recently, their involvement in worldwide data communications is becoming more and more pivotal. With the born and growth of the fifth generation of mobile communications (5G), a higher number of people and industries are envisioning SatCom networks as an additional mean to extend Internet coverage throughout the Earth and as a backup solution to increase the reliability of the terrestrial Internet.
Routing in Nanosatellite Networks
Industries and companies such as SpaceX, Google, and Facebook, are designing constellations made of thousands of small satellite (called micro- and nano-satellites) to be deployed in the next few years in order to build a universal “Space Internet” able to support the classical and legacy terrestrial Internet. However, a lot of challenges from several viewpoints are still open, such as how to route the information throughout this network considering the strict hardware constraints of these space nodes.

5G satellite/terrestrial integrated networks
SatCom networks became a viable solution to improve the current Internet connectivity in the vision of the upcoming 5G technologies. Satellites can offer higher coverage (they do not suffer from geographical limitations), reliability (they cannot be damaged by harmful events such as natural disaster or wars), and extend Internet connection to rural and remote areas where there is no other kind of telecommunication infrastructure (and the cost to build a terrestrial network from scratch would be prohibitive). However, the employment of networking solutions designed and developed for terrestrial networks is not straightforward.

Internet of Thing (IoT)
A lot of different IoT communication protocols are available on the market. However, their communication capabilities and coverage areas are limited. We are developing a solution based on a flying IoT gateway equipped onboard an UAV, which allows users to collect data from IoT sensors and forward them towards the Internet exploiting cellular communications (if available) or satellite connectivity (when needed).

Cyber-security
Nowadays a lot of important applications such as public services, Internet banking, and also systems devoted to defend are dependent on networks and computers. For this reason, they are often the target of malicious software (malware, spyware, etc...) attacks. Malware is software specifically designed to insert itself in a computer system without the approval of the owner using techniques such as trojans, backdoors, keylogger, and worms. To prevent these type of attack it is necessary to accurately detect malware and other types of intrusions.
Network Security
In particular, the integration of intrusion detection algorithms in a Software-Defined Networking (SDN) environment and in future 5G. We are developing an SDN-based Intrusion Detection System (IDS) where SDN switches extract and send all packet flow statistics to an SDN Controller which catalogs the incoming flows as normal or malware by using Machine Learning (ML) algorithms and instructs the SDN switches to drop the malicious flows.

Cyber-Physical security for Critical Infrastructures
The integration of Information Technology in the control systems of critical infrastructures (CI) brings totally new security threats. The "security by obscurity" paradigm that was generally accepted especially in the energy sector is no more efficient: the smart grid, and in general the smart city concept, requires strong communication between all the elements involved, which lead to many security risks; in this case however not only data are threatened, but also the safety of industrial processes, environment and human lives. The research activity focuses on the correlation between the cyber and the physical domain, in order to detect anomalies and improve the resilience of CI, and on attack injection and penetration strategies employing a Machine Learning (ML) approach for Smart Grids and Distributed Energy Resources application scenarios.
