| Abstract(in English) | The availability of global position system technology, rapid evolution of wireless data communication technologies and advances in mobile ad hoc networking create ample opportunities for supporting delay critical vehicular safety applications. Recently, delay critical nature of vehicular safety applications spurred interest in CDMA-based vehicular communications where the focus has been on mitigating interference induced by concurrent channel access. Although, the previous work takes into account the effect of the frequency channel and code assignment on SINR of a received packet, it neglects another factor, which is the relative distance of the transmitting, interfering, and receiving terminals. In this paper, we focus on a typical car accident scenario and argue on the need for multihop packet forwarding, a topology-aware channel assignment scheme, and an area-based packet forwarding scheme in the context of MMSA inter-vehicle communication system. We then propose a packet transmission scheduling scheme which largely alleviates near-far problem. Simulation results are presented to confirm performance improvements achieved by the proposed scheme. |
