Internet of Vehicles Interoperability using CoAP Protocol for Streaming Applications

Abstract

The Internet of Vehicles is widely applied in the context of connected systems nowadays. A vehicular network, a structure that provides vehicle-to-everything communication, can solve many issues in IoV. However, it deals with connectivity restrictions such as volatility, latency, bandwidth, and interoperability. To deal with these issues, applications can use lightweight IoT protocols such as the Constrained Application Protocol (CoAP). This paper presents a practical use case implemented using the CoAP protocol, considering a Multi-access Edge Computing (MEC) scenario, which runs cloud services at the network's edge and performs specific interoperable tasks. The evaluated scenario considers a V2X Streaming Service application that uses the V2X Information Service, an API to facilitate the interoperability between V2X communications and external applications. The study concludes that CoAP can fulfill the scenario's connectivity requirements and facilitate interoperability between IoT services.
