| Abstract(in English) | Reliability of Vehicle-to-vehicle (V2V) broadcast communication with CSMA/CA suffers from propagation issues such as fading and shadowing. In particular, communications around crossroads severely suffer from large propagation loss and Hidden Terminal (HT) problem, which are due to Non-Line-of-Sight (NLOS) propagation caused by buildings at the corners. V2V broadcast relay scheme with a relay station (RS) at intersection has been proposed and its improvement on the reliability has been shown. However, the performance of the scheme still suffers from HT problem. In this report, the RS is sectorized with directional antennas and receivers to alleviate the impact of packet collision. Both the theoretical and simulation results show that the packet delivery rate is remarkably improved by the sectorization, especially in dense networks. |
