Abstract

Vehicle-to-cloud is a network access model that aims to share computing resources for vehicles. In vehicle-to-cloud communication, reliable links are critical. Through multipath transmission, comprehensive utilization of heterogeneous wireless networks between the vehicle and the cloud server can effectively improve the reliability and efficiency of transmission. A large number of studies have pointed out that a receive butter can greatly improve the performance of multipath transmission in vehicle-to-cloud communication. However, most of these studies, which use receive buffers to improve multipath transmission performance, do not explicitly specify the design details of the receive butter. A classic design idea is to use a fixed length receive butter. However, this idea makes it difficult to determine the appropriate butter length in a complex vehicle-to-cloud communication scenario. This paper proposes a Dynamic Time-Threshold (DTT) receive buffer. The DTT receive buffer takes into account the instability of vehicular wireless networks, and dynamically adjusts the time-threshold so that the packets in the receive butter do not affect the overall communication performance due to premature departure or excessive waiting. We verified the performance of the DTT receive butter through a large number of simulations and real tests. By comparison, the performance of DTT receive butter is significantly better than the fixed length receive butter.
