Stateful Scheduling with Network Coding for Roadside-to-Vehicle Communication
In urban areas such as street blocks, media-rich services are delivering to moving vehicles through Access Points (APs) deployed on the roadside. To increase the capacity of wireless links for these services, a roadside-to-vehicle communication system based on a novel Stateful Scheduling with Network Coding (SSNC) strategy is proposed. A major innovation of SSNC is that it enables the scheduling on the roadside AP to fully utilize the states of received data from vehicles for an enhanced performance. Furthermore, a set of mechanisms are proposed to ensure reliable transmission in such highly dynamic and error-prone wireless channels. Extensive simulations show that SSNC achieves an increased throughput gain between 1.2 and 2.0 at various conditions.
