Towards Efficient Data Services in Vehicular Networks via Cooperative Infrastructure-to-Vehicle and Vehicle-to-Vehicle Communications
This paper investigates information services in vehicular networks via cooperative infrastructure-to-vehicle (I2V) and vehicle-to-vehicle (V2V) communications. In particular, we consider the cooperation among multiple roadside units (RSUs) in a bidirectional roadway scenario in providing data services. The primary objective is to best explore the channel efficiency for I2V/V2V communications to maximize the system performance. Specifically, we formulate the problem and propose a Maximum Service (MS) algorithm which combines the following three approaches. First, a hybrid I2V/V2V data dissemination scheduling policy is proposed to enable data services in the RSU’s coverage. Second, a cooperative V2V data sharing mechanism out of the RSUs’ coverage is proposed by assigning server-vehicles (SVs) to offload RSUs’ workload. Third, a data dissemination policy for SVs is proposed to further enhance overall system performance. Finally, we build the simulation model and give a comprehensive performance evaluation to demonstrate the superiority of the proposed solutions.
