Augmented Reality Based Smart City Services Using Secure IoT Infrastructure

Abstract

This paper presents an application of Augmented Reality (AR) within a smart city service to be deployed in the domain of public transport in the city of Novi Sad in Serbia. The described solution is focused on providing a simple and efficient method to citizens for accessing important information such as bus arrival times, bus routes and tourist landmarks using smart phones and AR technology. The AR information is triggered by image and geo-location markers and the data is provided via secure IoT infrastructure. The IoT infrastructure is based on bus-mounted IoT devices which utilize secure CoAP software protocol to transmit the data to the associated cloud servers. Description of the complete end-to-end solution is presented, providing the overall system set-up, user experience aspects and the security of the overall system, focusing on the lightweight encryption used within the low-powered IoT devices.
