Abstract

A switched-beam based multiple-input-multiple output (MIMO) vehicle-to-infrastructure (V2I) system can grant better system reliability as the signal-to-interference-plus-noise ratio (SINR) can be significantly optimized. In order to maximize the number of served vehicles by the simple switched-beam based V2I system, it is crucial to additionally introduce vehicle-to-vehicle (V2V) communication because (i) more than one vehicle might occupy a beam coverage, and (ii) vehicles may be out of the coverage region of a beam. In this paper, we proposed a cooperative infrastructure-beam allocation (IBA) and location-estimation (LE) scheme to optimize system coverage and reliability. IBA is an SINR optimization algorithm, and LE is a location-based proximity service for V2I and V2V communications respectively. Our simulation results show that a reliable beam coverage region in switched-beam V2I can be achieved with flexible value of SINR threshold. Also, the outage probability and average rates are directly dependent on set SINR thresholds. Finally, cooperation between V2I and V2V communication significantly improves the utility ratio which is further used as a metric for reliability.
