A Novel Distributed Context-Aware Radio Access Technology Selection Scheme For C-ITS Networks

Improving network performances to better support Cooperative Intelligent Transport Systems (C-ITS) services has been the subject of renewed efforts by academia and industry. To this end, the availability of multiple in-vehicle radio access technologies (RATs) has been exploited. In this paper, we propose a DIstributed and Context Aware Radio access Technology selection (DICART) framework for vehicular networks, formulated as Multi-Criteria Decision-Making (MCDM) problem. A validation methodology is then conducted based on OMNET++ full-stack network simulator to prove the effectiveness of DICART. Results show the benefits of our proposal under low and high density network configurations, in enhancing network performance perceived by end-users while considering the needs and constraints of used services.
