Demo: Vehicle-to-everything middleware supporting multiple access technologies for improving network coverage

Multiple access technologies such as IEEE 802.11p (11p) and long term evolution vehicle-to-everything (LTE-V2X) are expected to be used for vehicle-to-everything (V2X) communication. To improve the network coverage, terminals using different access technologies should be involved in the same V2X communication. To achieve this, we extended middleware designed for 11p to support multiple access technologies. In the middleware, access to hardware employing the 11p or other access technologies is abstracted, and bridging function among the abstracted hardware is implemented while keeping the same interface to the upper layers. Using the middleware, V2X communication among terminals employing different access technologies has been successfully demonstrated.
