Joint Task Management in Connected Vehicle Networks by Software-Defined Networking, Computing and Caching

As the rapid development of mobile communication technologies and the on-road information and entertainment demands, a growing number of vehicles equipped with communication, computing, caching and positioning devices will enable a huge network of connect vehicles, or vehicular network, with advanced capabilities to deliver not only the packets for the vehicle networks themselves, but also delay-tolerant data to increase the utilization efficiency of the vehicular network resource. In this paper, we introduce the concept of software-defined networking, computing and caching into vehicular networks to manage the delay-tolerant data deliver tasks from the Internet. We formulate this task management as an optimization problem and solve it by exploiting the optimal actions. Extensive simulation results are also presented to demonstrate the significant performance improvement of the proposed management.
