| Abstract(in English) | In realistic road environments, reflecting objects are able to degrade signal quality, preventing vehicles from being able to have direct communications. In this case, packet forwarding can be used to expand the communication range. Although a number of previous works target packet forwarding in CSMA/CA networks, to the best of our knowledge, there is not much work that address packet forwarding in CDMA networks. This paper analyzes and compares impacts of CSMA/CA and CDMA channel access methods on message delivery performance in inter-vehicle communications. The simulation results show that, in CSMA/CA, to achieve a sufficient delivery performance, it tends to require a complex forwarding approach that is able to efficiently suppress redundant forwarding. On the other hand, in CDMA, thank to near far effect, a simple packet forwarding scheme can provide a sufficient delivery performance. |
