The research team belonging to the Telematics Laboratory deals with the design, the investigation, and the optimization of ICT solutions for emerging and pioneering applications domains. Several activities are financed by research projects and carried out in cooperation of other Italian and/or foreign research teams. Currently, the main research interests include:
- Secure Internet of Things and Industry 4.0. Billions of objects are being to be shattered almost everywhere to enable smart services in different application domains, such as health care, logistics, energy management, military, environmental monitoring, and industryautomation (just to name a few). Thus, it is important to design effective, flexible, energy-efficient, lightweight, distributed, and secure communication architectures. In this context, research activities of Telematics Lab mainly focus on wireless sensor networks, channel access protocols, routing protocols, energyharvesting architectures, well as realtime communication architectures in industrial environments and middlewares for machine-to-machine systems. Security is also a vital in both Internet of Things and Industrial Internet of Things. Here, several research efforts are devoted to the definition and the implementation of distributed security architectures offering, also in federated and multi-authority scenarios, decoupled authentication and privacy-oriented authorization (i.e., Attribute-Based Access Control with ephemeral user identities) services, lightweight key agreement mechanisms, blockchain-enabled solutions, and flexible architectures providing dynamic and adaptable confidentiality requirements. In addition, Telematics Lab is also involved in standardization activities in the IETF 6tisch Working Group.
- 5G systems. The 5th Generation of mobile networks is being developed with the ambitious goal to support a very heterogeneous mixture of services, each with its own specific requirements. To this end, it should integrate and properly harmonize heterogeneous technical components and communication strategies. By leveraging the large experience on mobile networks matured in the past, the Telematics Laboratory is involved in several research activities related to the investigation of advanced transmission techniques based on Massive MIMO and Non Orthogonal Multiple Access, the design and the optimization of flexible radio resource allocation mechanisms fulfilling the quality of service requirements related to a mixture of heterogeneous services (including enhanced Mobile BroadBand, UltraReliable Low Latency and Massive Internet of Things), the integration of standardized technologies for broadcast and multicast services and NB-IoT, the definition of elastic and flexible 5G architectures based on machine learning, network slicing, Software Defined Networking, Network Function Virtualization, and Mobile Edge Computing paradigms, and the development of both analytical models and simulation tools supporting the performance analysis of 5G protocols and architectures.
- Datacentric and programmable architectures for the Future Internet. The emerging InformationCentric Networking paradigm recently gained worldwide the attention of academia and industrial research communities, thanks to its inherent ability to support upcoming technologies and services beyond the current host-centric Internet rationale. Research activities in this context include the design of innovative methodologies and communication architectures for multimedia, transportation, smart city, and Internet of Things services, the investigation of publish-subscribe communication strategies supporting the mobility of both consumers and producers, the design and the optimization of routing protocols, and the development of analytical models for the analysis of performance of datacentric communication protocols and architectures. In addition, Telematics Lab is also involved in standardization activities in the IRTF ICNRG Working Group. Future Internet is also going to be flexibly configurable, while hosting virtualized components and functions. Telematics Laboratory recently started important research activities related to Software Defined Networking and Network Function Virtualization, as well as their integration with Information Centric Networking, Internet of Things, and optical networks.
- Nanonetworks. The innovation process triggered by nanotechnologies is fostering the development of integrated devices with size ranging from one to few hundred of nanometers, very well suited for ICT, biomedical, industrial, and military applications. Here, the research activities include the characterization of different communication techniques for the nanoscale (including the exchange of electromagnetic waves in the Terahertz band and molecular diffusion), the design of energyharvesting and low-complex communication protocols and network architectures, and the development of both analytical models and simulation tools to be used for evaluating the performance of nanoscale communication systems, based on reference standards (like IEEE 1906.1).
- Internet models and network measurements. The characterization of complex and interconnected systems, such as the Internet, is essential to obtain precious insights on the network behavior. In this case, Telematics Laboratory is carrying out interesting research activities aiming at formulating analytical models for key aspects of Internet topology (for instance, diameter and shortest path). Network measurements are also fundamental for deeply understanding network behavior, type of traffic managed by an operator, thus being able to conceive innovative solutions improving system performance. Research activities related to network measurements include packet sampling techniques for scalable measurement systems in the Internet network, active and passive measurements for the analysis of mobile networks, and machine learning techniques for traffic classification and optimal resource management.
