Vehicular Delay-Tolerant Networks (VDTNs) encounter a great challenge with mobile data traffic, due to vehicles\' high mobility and complex wireless environment. Based on high-throughput mmWave communication, the roadside unit (RSU) plays a significant role in offloading the vehicle\'s data from cellular infrastructure to adjacent RSU. This paper formulate the selection of number and locations to deploy RSU in urban area as an optimization problem. A data-driven RSU deployment algorithm is proposed to maximize RSU utilization and reduce service waiting time. Real trajectory dataset is adopted to evaluate the proposed algorithm. The results show that the proposed algorithm reduces the average service waiting time and achieves a higher RSU utilization.
Keywords:data-driven; data offloading; roadside unit (RSU); Vehicular Delay-Tolerant Networks(VDTNs)
