Smart city services over a global interoperable Internet-of-Things system: the smart parking case

Abstract

This paper presents the implementation of a global smart parking use case that employs data streams coming from two different cities: Santander, in Spain, and Busan, in South Korea. In addition to the geographical distance, what is more important is that the platforms used in each of the cities for exposing their data are different. Santander's data is available through FIWARE-based interfaces while Busan's exposes oneM2M endpoints. The underlying Wise-IoT system used for the field trial, which is briefly described in this paper, addresses the challenge of fragmentation within IoT ecosystems by developing a novel framework to achieve global interoperability and mobility of IoT applications and devices. In this sense, the proof-of-concept implementation presented in this paper serves as a validator of Global IoT Services, enabling transparent user, and applications, roaming between the two cities involved in the pilot.
