Transmission of Augmented Reality Contents Based on BLE 5.0 Mesh Network

In recent years, Augmented Reality (AR) applications have appeared on smart devices (smartphones, smart glasses, etc.) that have expanded the visual perception of users. With the appearance of new technologies, a huge number of new services are created and the quality of service provision for them also plays a really important role. Thus, the task of Quality of Experience (QoE) introduces interest to suppliers, service developers and users. This article discusses the issues of QoE in the implementation of AR services in big cities with a high density of users but not all users have the Internet access. To solve this problem, we propose to use Bluetooth 5.0 technology (BLE 5.0) to access the network. The interaction between the client and the server can be carried out by using D2D communication on BLE 5.0 through smartphones of other users, which are described by the queuing system model. The proposed model of providing augmented reality services was simulated. The simulation results show delays in the delivery of data, which depends on the number of BLE 5.0 nodes through which data is exchanged between the AR client and AR server, and also on the load factor. © Springer Nature Switzerland AG 2018.
