Recent developments in the automotive and communication sectors enabled vehicles to operate as a highly mobile sensor platform. As the connected car concept continues to gain traction, Car-to-Cloud communication can support the transmission of collected data to the cloud, e.g., dynamic collection of new map information or localized weather forecasts. In addition to low latency and reliability, the data transmission requires a stable connection between a mobile vehicle and the cloud resources. Compared with only a single LTE connection such as regular TCP, leveraging multiple LTE interfaces (e.g. multipath protocols) can dramatically improve the transmission speed. However, MPTCP lacks the support to prioritize one path over another.
