HERMES: GS1-based Smart City Service Intercommunity

Abstract

The goal of Smart City is to improve the quality of civil life with the aid of efficient city operation and smart services built upon the ICT technology. In order for Smart City to operate successfully, citizens should actively create service, and also globally discover, access, and utilize them. However, existing Smart City platforms usually just pass services to the citizens unilaterally, and also have difficulty in sharing services globally due to the different operation of each platforms. In this paper, we propose a HERMES, a Smart City service intercommunity platform based on GS1 international standard. The HERMES consists of a HERMES ONS and a HERMES Client. The HERMES ONS enables the registration, discovery, access and utilization of Smart City services linked to urban resources, leveraging the GS1 ONS(Object Name Service), a service discovery standard associated with things. The HERMES Client enables members of cities to discover Smart City services which is optimized by location and language of citizen. For this purpose, the GS1 ID, international identification standard, is applied to physical and virtual urban resources for global identification. In addition, we defined Service Point as a medium for connecting citizen and service in the shape of barcode, data matrix, QR code, Bluetooth beacon and WiFi AP. We also modeled Life Cycle of services and Service Points using GS1 Core Business Vocabulary (CBV) and EPCIS standard to systematically manage creation, operation and disposal events. Finally, we implemented six use case scenarios such as traffic and administration, and verified the effectiveness of the HERMES in global Smart Cities.
