Abstract :
Vehicle to vehicle (V2V) communication is regarded as an essential means for enabling vehicle safety communications (VSC) to avoid traffic accidents. However, reliability of the communications severely suffers from wireless propagation on the road, such as deep fading due to multi-path and shadowing by surrounding buildings and vehicles. In this paper, a new vehicle-roadside-vehicle relay communication network employing multiple frequency bands is proposed to achieve more reliable V2V communications. By assigning lower frequencies such as 700 MHz for relay transmission, and higher frequencies of 5.8 GHz for direct communication, remarkable improvement can be obtained. In order to confirm the performance of the proposed relay network, computer simulations using QualNet network simulator assuming 200 vehicles at an intersection were conducted. The simulation results show that the packet delivery rate is remarkably improved by the proposed relay network.
