A vehicular network multipath management algorithm based on vehicular traffic

Abstract

Internet of Vehicles (IoV) uses a variety of communication technologies to connect vehicles, road infrastructure, and the cloud to achieve real-time information exchange and intelligent interaction between vehicles, vehicles and infrastructure, vehicles and service providers so as to improve traffic safety, traffic efficiency, and ride experience. Some scholars have proposed the use of Multipath Transmission Control Protocol (MPTCP) in IoV to improve its performance. However, researchers ignore the factors that influence it, such as user preferences, business characteristics, and actual needs, when constructing the transmission algorithm of IoV. In order to solve the above problems, this paper proposes a vehicular Network path management algorithm based on vehicular traffic, which includes two algorithms: the vehicular Network path management algorithm based on path characteristics and signal characteristics (PCSC) and the vehicular Network path management algorithm based on path characteristics and traffic service (PCTS). To verify the performance of the proposed algorithm, we designed a simulation experiment of vehicle movement in Mininet-WiFi software. The results show that the PCSC algorithm has higher path selection flexibility than the traditional MPTCP algorithm and the existing path transmission algorithms. The performance of the PCTS algorithm is more precise than the PCSC algorithm, which improves the efficiency and throughput of the network and solves the communication needs of users in different periods.
