Directory Service for Connected Vehicles

Vehicles are considered to constitute a large portion of new devices getting connected to 5G or beyond networks. Connected vehicles should be enabled to communicate with each other and roadside infrastructure securely, reliably, and in ultra-low latency. Vehicles should be able to discover and identify other vehicles in their surrounding very quickly. For this purpose, we propose a directory service that can store a huge number of vehicle's records and provide the records to querying vehicles in a very short latency (mostly less than 10 milliseconds). Similarly, it can dynamically update the records within a few seconds, while fully complying with record owner-centric privacy policy. The preliminary experiment results obtained from a simple testbed implementation with computers demonstrate the feasibility of the proposed system to meet the target lookup and update performance of connected vehicles.
