Abstract

5G-based hyper-connected Internet of Things environment is emerging, where various connectivities such as BlueTooth, WiFi, and 3/4/5G are provided. Since they have different communication characteristics, it is difficult to provide the user quality of experience when the handoff takes place according to the movement of the mobile devices between wireless access networks. For solving this problem, we propose a seamless video streaming protocol to satisfy the user quality of experience regardless of handoff. The proposed protocol can dynamically adjust streaming bit rate according to the network condition and also maintain fixed quantity of buffered audio–video data for the stable quality of experience level. The proposed protocol is designed independently of OS versions and CPU performance of terminals, which makes it easy to be implanted in various types of Internet of Things devices. Real-world experimental results show that seamless video streaming service can be guaranteed by carefully predicting the network dynamics over the heterogeneous wireless access networks. The protocol is now commercially deployed for over 5 million Long-Term Evolution subscribers of a South Korea telco, LG U+.

Highlights

Rapid increase in mobile and Internet of Things (IoT) devices and increased traffic accelerate the adoption of 5G networks. 5G network technology is being developed and standardized with the following three features: (1) high data rate, (2) low latency, and (3) massive connectivity.[11,12,13,14] Requirement for the high data rates should ensure peak transmission rates at 20 Gbps and guarantee user-experienced data rate at 100 Mbps.[11]
We have developed the proposed protocol over the upto-date Google Android mobile phone, which is equipped with Long-Term Evolution (LTE), WiFi, and 3G network interfaces
We focused on quality of experience (QoE) issue when multimediabased IoT devices are moved over the heterogeneous wireless network environment

Introduction

Rapid increase in mobile and Internet of Things (IoT) devices and increased traffic accelerate the adoption of 5G networks. 5G network technology is being developed and standardized with the following three features: (1) high data rate, (2) low latency, and (3) massive connectivity.[11,12,13,14] Requirement for the high data rates should ensure peak transmission rates at 20 Gbps and guarantee user-experienced data rate at 100 Mbps.[11]. 5G network technology is being developed and standardized with the following three features: (1) high data rate, (2) low latency, and (3) massive connectivity.[11,12,13,14] Requirement for the high data rates should ensure peak transmission rates at 20 Gbps and guarantee user-experienced data rate at 100 Mbps.[11] Requirement for the low latency is to reduce one-way transmission delay in the air section to 1 ms. It makes it possible to support mission critical services such as autonomous car and tele-medicine.[11,13].
