ARGOMENTI: Seminari

Mercoledì 11 Aprile 2018 alle ore 13:30 in Sala Riunioni VII Piano, Roberto Petroccia (NATO STO Centre for Maritime Research and Experimentation (CMRE)) terrà un seminario dal titolo “Underwater Communications and Networking”.

Abstract
Underwater networks are an enabling technology in a wide spectrum of different collaborative scenarios that find application to science, security, and industry. In the underwater domain, acoustics is the main technology used so far for communications, since radio and optical signals are greatly attenuated. Nonetheless acoustic communications in water are characterised by many challenges that are specific for the considered underwater environment: Long propagation delays, low bandwidth, sound speed variability, slow power signal attenuation, and many other environmental impairments. The wireless nature of the communications makes underwater acoustic networks vulnerable to various malicious attacks, yet, limited consideration has been given to the security of such networks. This talk presents the main challenges of underwater communication and networking, addressing also the current state of the art of security solutions in the underwater domain. Future steps towards software-defined strategies and collaborative approaches are introduced.
